Appwrite vs Supabase vs PocketBase 2026: The Open-Source Backend Showdown
A practical 2026 comparison of the three open-source, self-hostable backends worth building on — Supabase (the Postgres-based Firebase alternative with Auth, Realtime, Storage, Edge Functions and pgvector, and the biggest Next.js ecosystem), Appwrite (the batteries-included BaaS with a document data model, functions in many runtimes, built-in messaging, first-class mobile and Flutter SDKs, and Appwrite Sites hosting), and PocketBase (a single Go binary with embedded SQLite, a built-in admin UI, realtime and auth that you deploy in minutes). Data model, auth, realtime, functions, self-hosting, scaling, licenses, pricing and which one to build — or sell — your next app or template on.
