Verdict: The backend every solo builder should start with. Generous free tier, real Postgres underneath, and you can self-host if you outgrow the cloud.

What is Supabase?

An open-source platform that gives you a full backend in minutes: Postgres database, user authentication, file storage, real-time subscriptions, edge functions, and a dashboard to manage it all. Think Firebase but with a real database and no Google lock-in. You can self-host it.

Who is it for?

What does it cost?

Plan Price What You Get
Free $0 2 projects, 500MB DB, 1GB storage, 50K auth users
Pro $25/mo 8GB DB, 100GB storage, daily backups
Team $599/mo SOC2, priority support

Hidden costs: Database size is the thing that’ll push you to Pro. If you’re storing user-generated content, 500MB fills up.

Free tier reality check: Genuinely enough to launch and operate a small SaaS. Many solo products run on free tier.

How we’d actually use it

Building the backend for your tool directory:

  1. Create a Supabase project → instant Postgres database
  2. Define tables: tools, categories, reviews, users
  3. Enable Auth → user signup/login done
  4. Set up Row Level Security → users can only edit their own reviews
  5. Connect from your Next.js frontend → full CRUD in an hour

Time saved: Setting up auth + database + API manually: 2-3 days → 1 hour

FAQ

Q: Supabase or Firebase? A: Supabase. Real database, open source, self-hostable. Firebase locks you into Google’s NoSQL. The only reason to pick Firebase is if you need its specific real-time features or are deep in Google Cloud.

Q: Can Supabase handle production traffic? A: Yes. Many production apps run on Supabase. The Pro tier ($25/mo) handles most solo builder needs comfortably.

Q: Is self-hosting Supabase practical? A: Yes, via Docker. It’s well-documented. Do it when you need more control or want to cut costs at scale.
