WeWeb + Supabase Integration Guide
WeWeb and Supabase are the most powerful frontend-backend pair in the no-code ecosystem. WeWeb gives you pixel-perfect UI with full CSS control, while Supabase provides a production-grade PostgreSQL backend with auth, real-time subscriptions, and file storage — all without writing a server.
Why WeWeb + Supabase?
WeWeb is a frontend-only builder that needs a backend — and Supabase is the best backend for it. Unlike all-in-one tools, this stack keeps your data portable in a real PostgreSQL database, scales to millions of rows without cost spikes, and lets you use the full power of SQL. Together they cover the complete SaaS architecture: auth, data, storage, real-time updates, and edge functions.
Setting up the integration
In WeWeb, go to Plugins → Supabase and paste your Supabase project URL and anon key. WeWeb's native Supabase plugin auto-generates collections from your tables. Enable row-level security on every table in Supabase before connecting — this ensures users only access their own data even through the public anon key. For write operations, use WeWeb's built-in action system to call Supabase insert, update, and delete methods.
Authentication flow
WeWeb's Supabase plugin handles the full auth lifecycle: sign-up, email confirmation, magic links, OAuth (Google, GitHub, etc.), and session persistence. On login, Supabase returns a JWT that WeWeb stores in local storage and sends with every API request. Your RLS policies evaluate this JWT to enforce per-user data isolation. For role-based access, add a profiles table with a role column and reference it in your RLS policies.
Real-world use cases
This stack powers SaaS dashboards, client portals, internal tools, and marketplaces. A typical pattern: Supabase handles the data model and auth, WeWeb renders dynamic lists and forms, and Supabase edge functions handle backend logic like sending emails or processing payments. Teams at App Studio have shipped production apps for 10K+ users on this stack in under 6 weeks.
Common pitfalls
Never expose your service_role key in WeWeb — use the anon key and rely on RLS. Always enable RLS before connecting; forgetting it means any authenticated user can read all rows. Watch out for N+1 queries when loading related records: use Supabase's foreign table syntax (select *, profiles(*)) to fetch related data in a single request. Also enable realtime only on the tables that need it — broadcasting every table wastes bandwidth.
