Every developer who’s started a SaaS has been here:
You open a blank doc.
You start listing tools.
You spend 3 days reading comparison articles.
You ask Twitter. You get 40 different opinions.
You still don’t know what to pick.
I’ve been there three times. So I built something to fix it.
What I Built
appstackbuilder.com — an AI-powered tool that takes your:
- Budget
- App type
- Team size
- Skill level
…and generates a complete recommended stack in seconds.
It covers every layer:
- Authentication
- Database
- Hosting / Deployment
- Payments
- Analytics
- Error Monitoring
- And more
Completely free. No account required.
The Problem With Existing Advice
When you Google "best tech stack for SaaS 2026", most articles:
❌ Recommend the same tools regardless of budget
❌ Ignore per-seat pricing (which kills small teams)
❌ Assume you’re a senior full-stack developer
❌ Are written by people who haven’t shipped in years
The real answer to “What stack should I use?” is:
It depends on your budget, team size, and skill level.
That’s exactly what this tool accounts for.
🚀 What Makes It Different
1. Pricing That Actually Reflects Team Size
Most stack guides say things like:
“Use Clerk for auth — it has a free tier.”
What they often don’t mention:
- Clerk’s free tier caps at 10,000 MAU
- Paid plans are per-user
For a 5-person internal tool with heavy usage, that pricing model can completely change your cost assumptions.
👉 This tool factors team size directly into every cost calculation, keeping estimates realistic.
2. No-Code Mode for Non-Technical Founders
Not everyone building a product is a developer.
Toggle “No-Code Only”, and recommendations are filtered to platforms you can actually ship with:
- Bubble
- Glide
- Webflow
No backend engineering required.
3. Real Alternatives — Not Just One Pick
Instead of prescribing a single tool per category, each section shows:
✅ Up to 10 alternatives
✅ Clear pros & cons
✅ Room for informed decisions
Because stack choices are never one-size-fits-all.
4. Shareable Stack Links
Generated a stack?
Share it instantly via a link.
Perfect for:
- Co-founder discussions
- Team feedback
- Community validation
The Stack I Used to Build It
Since this is Dev.to and you’ll ask anyway:
- Framework: Next.js 16 (App Router)
- Database: Supabase
- AI: Multiple LLMs (OpenAI / Claude / Gemini)
- Auth: Custom JWT
- Hosting: Vercel
- Styling: Tailwind CSS + shadcn/ui
Yes — I used the tool to help validate my own stack choices.
Meta, I know.
What I Learned Building This
Pricing Data Is a Nightmare
Tools change pricing constantly.
Supabase updated their free-tier limits twice while I was building this.
Right now, I handle this via:
- Manual verification
- Scheduled checks
Not elegant, but it works.
No-Code Recommendations Are Hard
As a developer, my instinct is always:
“Just code it.”
Getting no-code suggestions right required significant feedback from non-technical founders. Still improving this area.
People Care More About Cost Than Features
The most-used feature is the monthly cost calculator.
More than tool names.
More than explanations.
Budget anxiety is very real for early-stage founders.

Free. No signup. Takes ~60 seconds.
