StreetJS vs Firebase
In one line: Another self-host vs managed decision. Firebase is Google’s Backend-as-a-Service (auth, Firestore, realtime, hosting, functions) that gets you to market fast; StreetJS is a backend framework you self-host, giving you owned data, a relational database, and no per-usage vendor lock-in.
Not a like-for-like comparison. Firebase is a managed platform; StreetJS is a framework you run on your own infrastructure.
At a glance
| StreetJS | Firebase | |
|---|---|---|
| Model | Self-hosted framework | Managed BaaS (Google Cloud) |
| Database | Relational: native PG driver, MySQL, SQLite + ORM | Firestore / Realtime Database (NoSQL) |
| Auth | Built in (JWT, sessions, RBAC, MFA) | Firebase Auth (managed, broad providers) |
| Realtime | Built-in WebSockets + channels | Realtime DB / Firestore listeners |
| Functions / compute | Your server / containers | Cloud Functions (serverless) |
| Where data lives | Your database | Google Cloud |
| Cost model | Your infra cost (predictable) | Pay-per-use (can scale unpredictably) |
| Offline / mobile SDKs | DIY / typed client SDK | Excellent first-party mobile SDKs |
| Vendor lock-in | None | Significant (data model + APIs) |
Where Firebase wins
- Time to market. Auth, database, hosting, and realtime in minutes with no servers to manage.
- First-class mobile SDKs with offline sync — hard to match for mobile apps.
- Serverless scaling handled for you, plus an integrated console and analytics.
Where StreetJS wins
- Relational data you own. SQL with a real schema and a first-party ORM rather than NoSQL document modeling, stored in your own database.
- Predictable cost and no lock-in. No pay-per-read pricing surprises; move hosts freely.
- Full control of the runtime, security model, and compliance posture — useful for regulated or cost-sensitive workloads.
Honest tradeoffs
Firebase is excellent for getting a product — especially a mobile app — live
quickly with minimal ops, and its offline-capable SDKs are best-in-class. StreetJS
fits teams that want relational data, predictable self-hosted costs, no vendor
lock-in, and control over the backend — at the price of running your own
infrastructure. For some stacks you can also integrate Firebase via the
@streetjs/plugin-firebase integration.
FAQ
Is StreetJS a Firebase replacement? For server-driven, relational apps, StreetJS covers auth, database, and realtime in one self-hosted framework. For mobile-first apps that rely on Firebase’s offline SDKs and serverless scaling, Firebase remains hard to replace.
Does StreetJS use NoSQL like Firestore? No. StreetJS is relational-first (PostgreSQL, MySQL, SQLite) with a typed ORM, which suits structured data and complex queries better than document stores.
