Fly.io vs Railway vs Render: Deploying Node.js Apps Without DevOps Overhead
Vercel is great for Next.js but not everything runs on Vercel.
Here's a comparison of the best platforms for deploying Node.js APIs, workers, and full-stack apps.
What We're Comparing
All three handle: Docker deployments, auto-scaling, managed databases, private networking.
The differences are in pricing, DX, and control.
Fly.io
Deploys Docker containers globally. Most infrastructure control of the three.
# Install flyctl
brew install flyctl
# Launch app
fly launch
# Deploy
fly deploy
# Scale
fly scale count 3 # 3 instances
fly scale vm shared-cpu-2x # upgrade VM
# fly.toml
app = 'my-api'
primary_region = 'lax'
[build]
dockerfile = 'Dockerfile'
[http_service]
internal_port = 3000
force_https = true
auto_stop_machines = true
auto_start_machines = true
min_machines_running = 1
[[vm]]
cpu_kind = 'shared'
cpus = 1
memory_mb = 512
Pricing: ~$5/mo for a 256MB VM. Generous free tier (3 VMs free).
Best for: Teams that want cloud control without full AWS complexity.
Railway
Connects to GitHub, detects your stack, deploys automatically. Zero config.
# Install CLI
npm install -g @railway/cli
# Login and deploy
railway login
railway init
railway up
Railway auto-detects Node.js, installs deps, and starts your app.
No Dockerfile required (though it supports one).
# railway.json (optional)
{
"build": {
"builder": "NIXPACKS"
},
"deploy": {
"startCommand": "npm start",
"healthcheckPath": "/health",
"restartPolicyType": "ON_FAILURE"
}
}
Pricing: $5/mo hobby plan with $5 credit. Usage-based above that.
Best for: Solo devs who want maximum DX, minimum configuration.
Render
Similar to Railway but with more focus on traditional web services.
# render.yaml (infrastructure as code)
services:
- type: web
name: my-api
runtime: node
buildCommand: npm install && npm run build
startCommand: npm start
envVars:
- key: NODE_ENV
value: production
- key: DATABASE_URL
fromDatabase:
name: my-db
property: connectionString
databases:
- name: my-db
plan: free
Pricing: Free tier (with spin-down after 15min inactivity). $7/mo for always-on.
Best for: Apps that need free tier for staging, or teams comfortable with IaC.
Managed Databases
All three offer PostgreSQL:
# Fly.io
fly postgres create --name my-db --region lax
fly postgres attach my-db --app my-api
# Railway
# Add PostgreSQL via dashboard — auto-injects DATABASE_URL
# Render
# Defined in render.yaml or dashboard
Choosing
| Fly.io | Railway | Render | |
|---|---|---|---|
| Setup speed | Medium | Fast | Medium |
| Control | High | Low | Medium |
| Free tier | 3 VMs | $5 credit | Yes (spin-down) |
| Best use case | Production APIs | Side projects | Teams |
My stack: Railway for side projects and prototypes. Fly.io when I need global regions
or more control. Render for teams that like YAML infrastructure config.
The Ship Fast Skill Pack includes a /deploy skill that generates Dockerfiles and deployment configs for Fly.io, Railway, and Render. $49 one-time.
