Xano vs Supabase: Choosing the Right Backend for Your No-Code App

The most common backend question in the no-code ecosystem: Xano or Supabase? Both are production-grade, both work with WeWeb and FlutterFlow, and both are used by thousands of SaaS companies. After building on both, here is when to use each — and when to use them together.

What They Actually Are

Supabase is a managed PostgreSQL database with built-in auth, realtime subscriptions, file storage, and edge functions. It's an infrastructure product — you get database primitives and connect your own API layer.

Xano is a no-code API builder with a built-in PostgreSQL database. It's an application-layer product — you build REST API endpoints with visual business logic (function stacks), and the database is managed underneath.

The key difference: Supabase gives you the database layer. Xano gives you the API + database layer. You can use them together (Xano connecting to Supabase), separately, or combine them.

When to Use Supabase Alone

Use Supabase alone when your business logic is simple. The Supabase REST API auto-generates endpoints for every table, and Row-Level Security handles access control.

For a WeWeb or FlutterFlow app with straightforward CRUD operations (create a task, read tasks for user, update task status, delete task) — Supabase's auto-generated API is sufficient. No need for Xano.

Also use Supabase alone when you want realtime subscriptions. Xano doesn't support Supabase Realtime — WeWeb and FlutterFlow connect directly to Supabase for realtime features.

When to Use Xano

Add Xano when your business logic is complex:
- Multi-step workflows (create order → update inventory → send notification → create invoice)
- External API integrations (Stripe webhook processing, Twilio SMS, SendGrid emails)
- Computed fields (pricing calculators, score algorithms, data transformations)
- Complex authorization (check workspace membership, verify subscription tier, rate limiting)

Xano's function stack makes this logic visual and maintainable. Doing the same thing in Supabase Edge Functions requires writing TypeScript.

Using Xano + Supabase Together

The combination we use most often: Xano as the API layer, Supabase as the database.

Setup: Xano connects to your Supabase PostgreSQL database directly (via the external database connection). Xano handles business logic and API endpoints. Supabase handles storage, auth (optionally), and direct realtime subscriptions for the frontend.

The benefit: you get Xano's visual function stack for complex logic AND Supabase's realtime and file storage. The downside: it's more infrastructure to manage.

Pricing Comparison

Supabase free tier: generous (500MB database, 2GB bandwidth, 50K monthly active users). Pro plan: $25/month for 8GB database. Scales predictably.

Xano free tier: limited (500 API requests/hour, limited database). Base plan: $85/month for 10K requests/hour. Launch plan: $175/month.

For low-traffic MVPs: Supabase alone is free and sufficient. For production apps with complex business logic: Xano + Supabase costs ~$110/month — still far cheaper than a custom backend developer.

Our Recommendation

Start with Supabase alone. If your logic fits in Supabase's auto-generated REST API + Edge Functions, there's no need to add Xano.

Add Xano when: (1) you have multi-step business logic that's becoming hard to manage in Edge Functions, (2) you need to integrate with multiple external APIs, or (3) your team is non-technical and Supabase's Edge Functions require TypeScript they can't maintain.

For most of our client projects, we use Xano + Supabase together — Xano for business logic, Supabase for PostgreSQL, realtime, and storage.
