Source: https://altcatalog.com/alternatives/supabase/ Category: Backend-as-a-service ## Overview - **Who it's for**: Developers building web, mobile, or AI applications who want a Postgres-backed backend without standing up separate services for auth, storage, and realtime — from solo/indie builders on the free tier up to production teams needing SOC2/HIPAA compliance on the Team and Enterprise plans. - **What you get**: A dedicated Postgres database with instant auto-generated REST and realtime APIs, built-in authentication and Row Level Security, S3-compatible object storage, globally-deployed Deno-based Edge Functions, and pgvector support for AI/vector search — all managed from one dashboard or self-hosted via Docker. - **How it works**: Every project provisions a dedicated Postgres instance that Supabase introspects to auto-generate a RESTful API (via PostgREST) and realtime websocket channels, while Postgres Row Level Security policies (integrated with Supabase Auth's JWTs) enforce per-row access control without a separate authorization server. ## Profile - **License**: Apache License 2.0 (verified 2026-07-13) - **Pricing model**: OSS + paid hosting (verified 2026-07-13) - **Starts at**: $25/mo (Pro) (verified 2026-07-13) - **Platforms**: Web - **Status**: active (verified 2026-07-13) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Appwrite](https://altcatalog.com/alternatives/appwrite.md) | 96 | BSD-3-Clause | Windows, macOS, Linux, Web | | 2 | [AWS Amplify](https://altcatalog.com/alternatives/aws-amplify.md) | 93 | Apache-2.0 | Web, iOS, Android | | 3 | [Convex](https://altcatalog.com/alternatives/convex.md) | 89 | FSL-1.1-Apache-2.0 | Web, Linux | | 4 | [InstantDB](https://altcatalog.com/alternatives/instantdb.md) | 85 | Apache-2.0 | Web, iOS, Android | | 5 | [Back4app](https://altcatalog.com/alternatives/back4app.md) | 81 | ? | Web, iOS, Android | | 6 | [Firebase](https://altcatalog.com/alternatives/firebase.md) | 81 | Proprietary | Web, iOS, Android | | 7 | [Parse Platform](https://altcatalog.com/alternatives/parse-platform.md) | 81 | Apache-2.0 | iOS, macOS, Android, Web | | 8 | [Xano](https://altcatalog.com/alternatives/xano.md) | 81 | Proprietary | ? | | 9 | [PocketBase](https://altcatalog.com/alternatives/pocketbase.md) | 78 | MIT License | Linux, Windows, macOS, Web | Alt Score = Verified coverage (90%) + Visibility (10%).
