10 Best PaaS Providers for Web Apps in 2026

rising_segun — Sat, 18 Jul 2026 00:00:00 +0000

Platform-as-a-service (PaaS) lets you deploy a web app without provisioning servers, patching OSes, or wiring CI/CD from scratch. You push code (usually from GitHub or GitLab) and the platform handles builds, SSL, routing, and scaling.

That is different from static hosting. A real web app needs a process that stays up, talks to a database, runs background jobs, and often keeps WebSockets or long-lived connections open. The best PaaS for that job is not always the same one that wins for a marketing site or a Next.js frontend.

This guide ranks 10 PaaS providers for web apps in 2026 , with seenode first: predictable fixed pricing, always-on services, managed databases, and a deploy-from-Git workflow that still feels like classic Heroku, without the surprise invoices.

Pricing and features below are based on publicly available docs as of July 2026 and can change by region and plan.

Key takeaways

Pick always-on PaaS (seenode, Railway, Render, Fly.io, Heroku) when you need persistent processes, WebSockets, or workers, not only serverless functions.
Pick frontend / edge PaaS (Vercel, Netlify, Cloudflare Pages) when the app is mostly static or serverless and you want global CDN performance.
Billing model matters as much as features. Fixed tiers (seenode, Render) beat usage metering if you hate surprise bills; usage-based (Railway, Fly.io) can win for bursty traffic.
For a full stack under ~$15/month with a database, seenode is usually the cheapest always-on option in this list.
Hyperscaler-adjacent tools (DigitalOcean App Platform, AWS Amplify) shine when you already live in that ecosystem.

How we evaluated

We scored platforms the way a small team actually chooses:

Stack fit: Can you run Python, Node.js, Go, or similar backends, not only static sites?
Developer experience: Git deploys, logs, previews, dashboards without a dedicated DevOps person.
Pricing predictability: Fixed tiers vs metered CPU/egress vs per-seat plans.
Databases & workers: Managed Postgres/MySQL, background workers, private networking.
Runtime model: Always-on processes vs serverless/edge (cold starts, WebSockets, timeouts).
Support: Docs quality and whether a human will help when a deploy breaks at 6pm.

For a deeper look at billing models specifically, see our Heroku alternatives decision framework.

1. seenode: best for predictable, always-on web apps

seenode is a developer PaaS built for shipping web services, workers, and managed databases without becoming an infrastructure team. Connect GitHub or GitLab, pick a repo, and get a public URL with SSL. You can even start a deploy before creating an account, claim it when you are ready, with a 7-day free trial.

seenode targets the gap left after Heroku’s free tier disappeared: always-on apps with Heroku-like simplicity and fixed monthly pricing. No cold starts, no per-request metering, no per-seat fees. That makes it a strong default for side projects, MVPs, and small SaaS products that need a real backend plus Postgres or MySQL.

Native runtimes include Python, Node.js, Go, and Elixir. You get centralized logs (7 days), private networking between services, zero-downtime deploys, horizontal or vertical scaling, and unlimited team members. Support is live chat with platform engineers, not a ticket black hole.

seenode key features

Git-based deploys from GitHub/GitLab with automatic builds and SSL URLs
Zero cold starts: always-on processes for WebSockets, SSE, and persistent connections
Managed PostgreSQL and MySQL in the same project as your apps and workers
Fixed monthly pricing , charged daily, with no per-seat or per-request surprises
Unlimited team seats and pair-debugging support from the people who build the platform

seenode pricing (as of July 2026)

Pricing starts at $3/month for a basic web service. A common starter stack with web + Postgres is often around $7 to $11/month , depending on tier. Larger setups stay fixed-tier; seenode’s public comparison shows a 3-app + Postgres + storage stack at roughly $15.50/month vs much higher on Render for a similar footprint. Explore current numbers on seenode pricing.

Best for: Solo developers and small teams who want always-on apps, a database, and a bill they can predict.

Skip if: You need multi-region edge by default or a huge add-on marketplace on day one.

2. Railway: best for Heroku-like workflows with usage billing

Railway is the platform many teams tried first after leaving Heroku. Deploy from Git, Docker, or the CLI; attach managed databases; use private networking between services. The DX is fast, and the product feels built for full-stack apps rather than marketing sites.

The tradeoff is usage-based pricing. Quiet apps can stay cheap; sustained traffic or chatty services can push the bill up quickly. That is fine if you watch usage, painful if you do not.

Railway key features

Git, Docker, and local deploy paths with rollbacks and observability
Managed databases and persistent volumes
Private networking and TCP proxies
Unlimited preview environments on higher plans
Usage-based Hobby and Pro tiers

Railway pricing

Hobby includes a small usage credit; Pro is commonly around $20/month with included credit, and real production apps often land in the $20-30+/month range depending on CPU, memory, and egress.

Best for: Variable traffic and teams that like Railway’s project model.

Skip if: You need a fixed invoice every month.

3. Render: best for production-ready defaults

Render is a unified cloud for web services, static sites, background workers, cron jobs, and managed Postgres/Redis. Git auto-deploys, zero-downtime releases, and private networking make it a common “boring production” choice for agencies and startups.

Pricing is more expensive than seenode for comparable always-on stacks, especially once you add Postgres with production features and a paid workspace. You pay for stability and a mature feature set.

Render key features

Automatic Git deploys and Docker support
Native workers, cron jobs, and preview environments
Managed PostgreSQL and Redis with private networking
Infrastructure as Code via render.yaml
DDoS protection and zero-downtime deploys

Render pricing

Free tiers exist for experiments; production web + Postgres setups often start in the tens of dollars per month and climb with PITR, larger DBs, and team plans.

Best for: Client work and teams that want opinionated production defaults.

Skip if: Budget is under ~$15/month for web + database.

4. Vercel: best for Next.js and frontend-centric apps

Vercel owns the Next.js deployment experience: Git integration, preview deployments per PR, and a global edge network. Serverless and edge functions cover APIs, but the platform is optimized for frontend and JAMstack patterns, not long-running backends.

If your “web app” is mostly React/Next with serverless APIs, Vercel is excellent. If you need always-on workers, WebSockets, or a traditional app server, look at seenode, Railway, Render, or Fly.io instead.

Vercel key features

First-class Next.js and modern frontend frameworks
Preview deployments and team collaboration controls
Edge network, serverless functions, and AI SDK tooling
Integrated storage options (Blob and related services)

Vercel pricing

Generous free hobby tier; Pro from about $20/month per seat, plus usage for functions and bandwidth on heavier apps.

Best for: Next.js products and frontend teams.

Skip if: You need persistent servers, workers, or cheap always-on Postgres next to the app.

5. DigitalOcean App Platform: best for hybrid PaaS + cloud

DigitalOcean App Platform sits on top of DigitalOcean’s broader cloud: deploy from Git or containers, mix services/workers/static sites, and grow into Droplets, managed databases, or GPU/AI products when you need them.

It is a solid middle ground when you want PaaS simplicity with an escape hatch into classic cloud infrastructure, without jumping straight to AWS complexity.

DigitalOcean App Platform key features

Git-based deploys with component architecture (services, workers, static sites)
Built-in HTTPS, CDN, and app-level logs
Vertical and component-level scaling
Path into Droplets, managed DBs, and AI/GPU products

DigitalOcean pricing

Static/free tiers for light apps; paid App Platform plans commonly start around $5/month , with costs rising as you add dedicated CPU and databases.

Best for: Teams that want managed deploys plus optional DO infrastructure.

Skip if: You only need a tiny always-on API and want the absolute lowest fixed bill.

6. Fly.io: best for multi-region and proximity to users

Fly.io runs full containers close to users across many regions. That is powerful for latency-sensitive apps and global products. Machines can scale to zero, which helps cost, but managed Postgres and always-on capacity change the economics fast.

Expect a steeper learning curve than seenode or Railway. The payoff is control over where your app runs.

Fly.io key features

Global regions and Anycast networking
Full Docker/OCI workloads with scaling options
Optional managed Postgres (watch the price jump)
Strong fit for latency-sensitive APIs

Fly.io pricing

Usage-based compute can look cheap for idle hobby apps ( often under $15/month without managed Postgres). Adding managed Postgres frequently pushes totals toward ~$45-50/month , a cliff many comparison posts underplay.

Best for: Multi-region and performance-sensitive workloads.

Skip if: You want the simplest dashboard and a flat invoice.

7. Heroku: best for mature, classic PaaS

Heroku invented the dyno mental model many of us still use. Buildpacks, add-ons, review apps, and a huge ecosystem remain useful. The platform is stable and familiar, but innovation is slower, and pricing is rarely the cheapest option for a small always-on stack.

Still a valid choice if your team already knows Heroku or depends on specific add-ons.

Heroku key features

Dyno-based scaling and Cloud Native Buildpacks
Large add-on marketplace (data, monitoring, messaging)
Private Spaces and compliance-oriented offerings
Mature CLI and developer workflow

Heroku pricing

Basic dynos often start around $7/month , with Postgres and add-ons stacking quickly for production.

Best for: Teams standardized on Heroku’s ecosystem.

Skip if: You are cost-sensitive or want the newest PaaS DX.

8. Netlify: best for JAMstack and Deploy Previews

Netlify popularized Deploy Previews and a polished JAMstack workflow. Global CDN, serverless/edge functions, forms, and identity features make it strong for content sites and frontend apps, not a replacement for a classic always-on API host.

Netlify key features

Deploy Previews tied to pull requests
Serverless and edge functions
Global CDN and build tooling
Identity and forms on higher plans

Netlify pricing

Free personal tier; paid plans commonly from about $9-20/user/month plus usage.

Best for: Marketing sites, docs, and frontend-heavy products.

Skip if: Your core product is a long-running backend.

9. AWS Amplify: best for AWS-centric frontends

AWS Amplify helps frontend teams deploy apps and wire into Cognito, AppSync, S3, and the rest of AWS. Pull request previews and Amplify Hosting are convenient if you already live in Amazon’s ecosystem.

The downside is classic AWS: powerful, but complexity and cost visibility can grow quickly once you leave the happy path.

AWS Amplify key features

Hosting with PR previews
Auth, storage, and API integrations with AWS services
Amplify Studio and CLI for backend wiring
Fits teams already standardized on AWS

AWS Amplify pricing

Pay for Amplify Hosting and underlying AWS resources. Entry can look cheap; production AWS bills need monitoring.

Best for: Frontend apps that must plug into AWS deeply.

Skip if: You want a simple Heroku-style PaaS with one predictable invoice.

10. Cloudflare Pages: best for edge speed and static-first apps

Cloudflare Pages deploys sites and JAMstack apps onto Cloudflare’s global network, with Pages Functions (Workers) for dynamic behavior at the edge. Unlimited bandwidth on Pages plans is a real advantage for traffic spikes.

Like Vercel and Netlify, it is not the first pick for traditional always-on app servers, but for edge-first architectures it is hard to beat on latency and CDN reach.

Cloudflare Pages key features

Git-integrated continuous deployment
Pages Functions on the edge network
Global CDN performance and DDoS posture
Unmetered bandwidth on Pages plans

Cloudflare pricing

Generous free tier; paid Workers/Pages plans for heavier compute and team features.

Best for: Static and edge-rendered apps that need global speed.

Skip if: You need a classic always-on Node/Python process next to managed Postgres in one dashboard.

How to choose the right PaaS

Use this shortcut:

Side project or MVP under $15/month with a database → seenode
Heroku-like DX and you accept usage bills → Railway
Agency / client production defaults → Render
Next.js-first product → Vercel (pair a backend PaaS if you outgrow serverless)
Already on DigitalOcean → App Platform
Need many regions → Fly.io
Frontend/edge only → Netlify or Cloudflare Pages
Deep AWS integration → Amplify

FAQ

What is the best PaaS for a large-scale web app?

For large scale, prioritize autoscaling, observability, and operational maturity. Render , Fly.io , and hyperscaler-adjacent platforms (DigitalOcean, AWS) are common choices. Many teams still start on a simpler always-on PaaS like seenode or Railway , then split services or move parts of the stack when traffic justifies it. Pure VPS/IaaS wins only when you need OS-level control that PaaS will not give you.

Is PaaS better than VPS hosting for web apps?

For most product teams, yes. PaaS is faster to ship and cheaper in engineering time. Choose a VPS when you need custom kernels, unusual networking, or specialized software that no PaaS supports. Do not pick a VPS just to “save money” unless you enjoy being on-call for patching and SSL renewals.

Which PaaS is best if I am leaving Heroku?

Closest workflow: Railway. Closest economics for a small always-on app + database: seenode. Closest “enterprise boring”: Render. Details and cost tables: Heroku alternatives decision framework.

Can I host a full-stack app with a database on these platforms?

Yes on seenode , Railway , Render , DigitalOcean , Fly.io , and Heroku. On Vercel , Netlify , Amplify , and Cloudflare Pages , you typically attach an external database (Neon, PlanetScale, Supabase, RDS, etc.) and keep the host focused on frontend/serverless.

How do I migrate to seenode?

Point a GitHub or GitLab repo at seenode, set build/start commands and env vars, provision Postgres or MySQL if needed, and deploy. Start from the seenode docs or just deploy from GitHub.

Ship your web app without the infrastructure tax

If you want always-on web services, workers, and managed databases with fixed pricing and no per-seat fees , seenode is built for that: predictable invoices, no per-seat fees, and a deploy loop that gets out of your way.

Heroku Alternatives Decision Framework: What Actually Matters When Picking a PaaS

rising_segun — Fri, 30 Jan 2026 10:43:00 +0000

TL;DR: After Heroku killed their free tier, everyone rushed to Railway, Render, and Fly. Three years later, here is the framework that actually matters for picking between them based on billing model, not feature lists.

When Heroku discontinued their free tier in November 2022, hundreds of thousands of projects had to migrate. Most comparison posts you will find today are just feature lists. This guide focuses on what matters in practice after using all of these platforms in production: how they bill you and how that interacts with your traffic pattern and your tolerance for surprise invoices.

Quick Decision Helper

Need predictable costs? → Fixed tiers (Seenode, Render)
Traffic varies wildly? → Usage-based (Railway, Fly.io)
Just a static site? → Serverless (Vercel, Netlify)
Need enterprise features? → Render
Budget under $15/month? → Seenode or self-hosted

The One Thing Everyone Gets Wrong

People compare features. They should compare billing models.

Your choice is almost never about:

"Which has the best dashboard?"
"Which supports my framework?"
"Which has the nicest CLI?"

Most modern PaaS providers have reasonable dashboards, support the common languages and frameworks, and give you some batteries-included tooling. The real question is:

Which billing model matches your traffic pattern and your budget anxiety tolerance?

If you choose the wrong model, the platform can be technically great and still feel terrible to use, because every deploy becomes a question of, "What will the bill look like next month?"

Migrating from Heroku?

If you're coming from Heroku's free tier, the biggest shock is usually the cost. Heroku's free tier spoiled us—most alternatives start at $4–20/month. The good news: you're getting better performance, more predictable uptime, and actual support.

The closest "drop-in" replacements are Railway (similar workflow) and Seenode (similar economics). Render feels more "enterprise" but costs more.

The Three Billing Models That Emerged

Over the last few years, three dominant billing models have crystallized.

Model 1: Fixed Per-Node Tiers (Seenode, Render)

You pay a flat monthly rate for provisioned capacity. Whether your app is slammed 24/7 or idle for half the month, the bill barely moves.

Predictable: You know roughly what next month’s invoice will be.
Simple: You pay for the size and count of services and databases, not for each individual CPU cycle.
Wasteful at low usage: You still pay even when your app is mostly idle.

Best for: Steady traffic, budget-conscious teams, and people who hate billing surprises.

Example costs (Jan 2026):

Seenode: $4/month (Basic web + Tier 1 Postgres)
Seenode: $11/month (Standard web + Tier 2 Postgres)
Render: $13/month (Starter web + Basic Postgres)

If your app is always on and has relatively consistent traffic, fixed tiers tend to win. You trade theoretical efficiency for billing sanity.

Model 2: Usage-Based Metering (Railway, Fly.io)

You pay for what you actually use: per-minute compute, per-second CPU, per-request, per-GB of storage and bandwidth.

Efficient at low/variable usage: Quiet apps can be very cheap.
Scales smoothly with traffic: Spikes cost more, but you do not need to resize instances manually.
Unpredictable: If you do not monitor usage, bills can drift or spike.

Best for: Variable traffic, developers who monitor usage, or apps that must be 24/7 online but receive low or bursty traffic.

Example costs (Jan 2026):

Railway: $20–30/month typical (Pro plan with $20 included credit), can spike to $50+ with sustained traffic.
Fly.io: $0–15/month for hobby apps without managed Postgres, $43–50/month once you add managed Postgres.

Usage-based systems reward teams that:

Instrument and monitor their apps.
Understand their baseline traffic profile.
Are willing to occasionally dig through billing dashboards.

If that doesn't describe you, this model can feel like a tax audit every month.

Model 3: Serverless (Vercel, Netlify)

You pay per function invocation. There is no persistent application process; instead, your code runs on demand in short-lived serverless functions.

Amazing for JAMstack: Static-first sites, Next.js, Astro, Remix, etc.
Great for spiky traffic: You only pay when people actually hit your endpoints.
Awkward for stateful backends: Long-lived connections, background jobs, or session-heavy apps do not fit naturally.

Best for: JAMstack apps, modern React frameworks, marketing sites, and dashboards with lightweight APIs.

Not suitable for: Traditional backend frameworks like Django, Rails, or Express apps that rely on in-memory state, sticky sessions, or complex background processing.

If your mental model of “backend” is a long-running process with queues, WebSockets, and custom workers, serverless can feel like fighting the platform instead of using it.

What It Actually Costs (Real Numbers, Jan 2026)

To make this concrete, consider a typical full-stack app:

Web service with roughly 1 GB RAM
Managed Postgres with 1 GB storage (plus sensible defaults)

Here is what that looks like across platforms today:

Platform	Monthly Cost	Billing Model	What You Get
Seenode	$11	Fixed tier	Standard web + Tier 2 Postgres, always-on
Fly.io	$12–15	Usage-based	Self-managed Postgres (or $43–50/month with managed Postgres)
Railway	$20–30	Usage-based	Pro plan with $20 credit, can spike with traffic
Render	$57+	Fixed tier	Web service + Postgres with PITR and zero-downtime deploys

The cliff nobody mentions: Fly.io looks cheap ($0–15) for hobby apps without managed Postgres, but once you turn on managed Postgres, the bill often jumps up rather fast ($45-50). The platform is still good—but the mental model of it being "cheap" quietly disappears.

The Decision Framework

Stop comparing dashboards and feature checklists. Walk through these questions instead.

Question 1: Can you tolerate variable billing?

Yes, I monitor usage and I am okay with variance

Choose Railway or Fly.io. You get flexible scaling and can squeeze out cost efficiencies if you understand your workload.
No, I need predictable monthly costs

Choose Seenode or Render. Fixed tiers mean you know the number before the invoice arrives.

If you feel stress every time a cloud bill arrives, treat predictability as a core feature—not a nice-to-have.

Question 2: What is your budget ceiling?

Use this as a rough mapping for a single production app with a database:

$5–15/month
- Seenode (Basic or Standard tiers: $4–11/month)
- Self-hosted on a low-cost VPS (Hetzner, Contabo, etc.), if you are willing to manage infra.
$20–50/month
- Railway (Pro plan, potentially higher with sustained traffic)
- Seenode higher tiers if you need more resources but want fixed pricing.
$50–100/month
- Render (app + managed Postgres with PITR)
- Fly.io with managed Postgres and multi-region setups.
$100+/month
- Render with enterprise-style features (SSO, high availability, advanced backups).

These numbers change over time, but the shape of the tradeoffs does not.

Question 3: Do you need enterprise features?

Yes – compliance, SOC2, SSO, PITR, zero-downtime deploys are non-negotiable

Lean toward Render. It is opinionated, boring in the best way, and designed for teams that want stability and support more than they want to save $20/month.
No – I mostly need HTTPS, logs, deploys, and a Postgres database

Seenode or Railway are usually a better fit. They give you the essentials without pushing you up into enterprise pricing.

If legal and compliance teams are involved, the cheapest platform is rarely the right one.

Question 4: Is global distribution critical?

Yes – my users are spread across regions and latency matters

Fly.io shines here, with multi-region deployments as a first-class concept.
No – most users are in one region and latency is fine

Seenode, Railway, or Render will do the job. Focus on simplicity and billing, not on global replicas you may never need.

What I Actually Use (and Why)

Disclosure: I work on Seenode, so understand the bias. That said, here is the honest breakdown of what I reach for in different scenarios.

For hobby projects

Choice: Seenode Basic ($4/month)
Why: It is the cheapest always-on option with a database included that still feels like Heroku. I can git push, get HTTPS and logs, and forget about it. At $4/month, it is psychologically close to “free” but without the randomness of free-tier shutdowns.

For client projects

Choice: Render
Why: Clients pay for peace of mind. Render gives you:
- Managed Postgres with point-in-time recovery (PITR)
- Zero-downtime deploys
- A mature, predictable environment

The extra cost (often $57+/month for a typical setup) is easy to justify compared to the cost of a single outage for a paying client.

For high-traffic production on a coffee-priced budget

Choice: Self-hosted on Hetzner (or similar low-cost VPS) with Coolify or Dokploy.

If you need:

Many services
Heavy background workers
Higher traffic

…and still want to stay under $50/month, managed PaaS platforms become harder to justify. Self-hosting:

Compresses all infra cost into a single VPS bill.
Gives you full control over resource allocation.
Moves all responsibility for uptime onto you.

Downtime in this model is almost always your fault—bad deploys, poor monitoring, slow incident response. You save money but pay in operations time and cognitive load.

The Missing Costs Nobody Mentions

Looking only at base instance prices hides a lot of real-world cost. Four common gotchas:

Common mistake: Picking a platform based on the cheapest headline price, then getting surprised by egress fees, backup costs, or usage spikes. Always factor in the hidden costs.

1. Egress fees

Railway: $0.05/GB outbound
Fly.io: $0.02/GB outbound

If you run a webhook-heavy app, file-serving API, or anything data-intensive, egress can quietly add $50–200/month on top of your compute bill.

2. Railway’s credit system

Hobby: $1/month subscription with $5 usage credit
Pro: $20/month subscription with $20 usage credit

Once your actual usage exceeds that credit, metered charges apply. For small apps this is fine; for growing usage it can turn into an invisible ratchet until you look closely at the billing breakdown.

3. Stopped machines and storage

Fly.io continues billing storage even when machines are stopped: around $0.15/GB/month.

Stopping everything in a panic does not always reset the bill to zero. Persistent volumes, snapshots, and images keep ticking along until you explicitly delete them.

4. Database backups and safety nets

Render: Includes PITR on paid database plans. This is a genuine safety feature.
Railway / Fly.io: You usually need to:
- Configure backups yourself, or
- Rely on third-party tools, or
- Accept a more limited restore story.

This is invisible until something goes wrong—and then it is the only line item that matters.

The Closest Alternatives to OG Heroku

If what you really want is “git push and boom, we are live”, here is how the modern landscape looks:

Railway – Captures a lot of the Heroku magic. Simple, fast to onboard. The tradeoff is billing unpredictability if you are not watching usage.
Seenode – Leans into Heroku-style simplicity with Heroku-free-tier-style economics. At $4/month, it is psychologically very close to the old “free dyno” experience.
Render – The most production-ready choice, especially for serious projects and client work. More expensive, but you get strong defaults and guardrails.

Everything else in the ecosystem is either:

More serverless and front-end centric (Vercel, Netlify), or
More infra-heavy and DIY (Cloud providers, raw Kubernetes, self-hosting).

They can be great—but they are no longer "Heroku for everyone."

Quick Comparison Summary

Platform	Best For	Monthly Cost	Billing Model	Key Differentiator
Seenode	Hobby projects, predictable costs	$4–11	Fixed	Cheapest always-on with DB
Railway	Variable traffic, Heroku-like workflow	$20–30+	Usage-based	Simplicity + flexibility
Render	Client work, enterprise needs	$57+	Fixed	Production-ready defaults
Fly.io	Global distribution, bursty traffic	$0–50+	Usage-based	Multi-region by default

Key Takeaways

Billing model matters more than features — Match it to your traffic pattern
Hidden costs add up — Egress, storage, backups can double your bill
Predictability vs. flexibility — Choose based on your tolerance for billing surprises
Enterprise features cost money — Only pay for them if you actually need them
Self-hosting saves money — But you pay in operational overhead

So… What Should You Actually Do?

When choosing a PaaS in 2026, ask yourself one question first:

Is predictable billing or pay-as-you-go flexibility more important for this project?

Then layer on:

How much operational burden am I willing to accept?
Do I actually need global distribution, or does a single region work?
Is this a hobby app, client app, or revenue-critical system?

Once you answer those honestly, the "Heroku alternatives" list narrows itself down very quickly.

Use this checklist as you evaluate providers:

Your stack (language, framework, database)
Rough traffic pattern (requests/day or month)
Maximum monthly budget
Whether you need enterprise features (compliance, SSO, etc.)

With clear answers to those questions, you can quickly narrow down to one or two platforms whose billing models actually fit how your app is used.
