Baasix vs Firebase
Open-source PostgreSQL vs Google’s proprietary cloud
Firebase is Google’s proprietary app platform built around Firestore, a NoSQL document store. Baasix takes the opposite stance: open-source, self-hosted, and relational. You keep your data in your own PostgreSQL with real relations, joins, and SQL power — while still getting the instant APIs, auth, and realtime that made Firebase popular, plus an App Builder and visual workflows Firebase never had.
The short version
Choose Firebase for mobile-first apps that lean on offline sync and Google’s managed ecosystem. Choose Baasix when you want relational data, no vendor lock-in, predictable costs, and a backend your team fully controls.
Feature by feature
| Feature | Baasix | Firebase |
|---|---|---|
| License & pricing | MIT backend · $9.99/yr per domain for the UI | Proprietary · pay-as-you-go (Blaze) after free tier |
| Self-hosting | Runs on your servers, your rules | Google Cloud only |
| Database model | Relational PostgreSQL: joins, constraints, SQL | NoSQL documents (Firestore / RTDB) |
| Complex queries | 50+ operators, relation traversal, aggregation | Limited queries, no server-side joins |
| Realtime | Socket.IO subscriptions with Redis scaling | Excellent realtime & offline sync |
| Authentication | 35+ OAuth providers, passkeys, 2FA | Firebase Auth, many providers |
| Built-in App Builder | Admin panels & internal tools from 27 blocks | Console manages services only |
| Visual workflows | 17+ node types, form-to-workflow webhooks | Cloud Functions require code |
| Full-text search | PostgreSQL FTS with auto GIN indexes | Requires Algolia/Typesense integration |
| Geospatial queries | PostGIS: radius, distance, polygons | Geohash workarounds |
| Vendor lock-in | Standard Postgres — take your data anywhere | Deeply tied to Google Cloud APIs |
| Cost predictability | Flat license + your hosting bill | Per-read/write billing can spike |
| Mobile SDKs & offline | TypeScript SDK (web, Node.js, React Native) | Mature native SDKs with offline-first sync |

- You need to self-host for compliance, cost, or data ownership
- You want admin panels, workflows, and search without extra services
- Surprise usage bills are unacceptable
Choose Firebase if…
- You are building a mobile app that depends on offline-first sync
- You want Google to run everything for you
- Your app fits comfortably in Firestore’s document model
Common questions
Is Baasix an open-source Firebase alternative?
Yes. Baasix covers the core Firebase use cases — instant APIs, authentication, realtime updates, and file storage — but is MIT-licensed, self-hosted, and built on relational PostgreSQL instead of a proprietary NoSQL store.
How do costs compare between Baasix and Firebase?
Firebase bills per operation on the Blaze plan, which can grow unpredictably with traffic. Baasix costs are flat: the open-source backend is free, the Admin UI license is $9.99/year (or $49 lifetime) per production domain, and you pay only for your own hosting.
Does Baasix support realtime like Firebase?
Baasix provides realtime subscriptions over Socket.IO with Redis-backed horizontal scaling. Firebase still leads for offline-first mobile sync; for web dashboards, live collections, and notifications, Baasix realtime covers the same ground.
