RustaBase vs Convex
Convex is a reactive backend where you write TypeScript queries and mutations that run inside its database. RustaBase gives you PostgreSQL, standard APIs, and hosting for your app.
In one sentence
Choose Convex if you want an all-TypeScript, reactive programming model; choose RustaBase if you want SQL, standard PostgreSQL, and clients in more languages.
Side by side
| RustaBase | Convex | |
|---|---|---|
Data model | PostgreSQL tables with SQL | Document-relational database accessed through TypeScript functions |
How you query | SQL, REST API, and client SDKs | TypeScript query and mutation functions |
Realtime | Realtime subscriptions on records | Every query is reactive by default |
Languages | JavaScript, Go, and Dart clients | TypeScript-first; other clients available |
Application hosting | Built in with previews and rollback | Backend only; host the frontend separately |
Portability | Standard PostgreSQL | Convex-specific data and function model |
Open source | RustaBase OSS (Rust) | Open-source backend available |
Competing products change often. Check their current documentation for exact features, limits, regions, and pricing before deciding.
Where RustaBase is stronger
- Any tool that speaks PostgreSQL works with your data: BI tools, migrations, SQL clients.
- Clients for Go and Dart, not only TypeScript.
- Frontend hosting and previews included.
Honest trade-offs
- Convex's reactive model removes a lot of cache and sync code for TypeScript apps.
- Convex gives end-to-end type safety from database to UI.
- Convex has strong developer experience for rapid TypeScript prototyping.
When Convex may be the better choice
- Your whole stack is TypeScript and you want reactivity without writing subscriptions.
- You prefer writing backend logic as functions instead of SQL.
Moving from Convex
- Design PostgreSQL tables from your Convex schema.
- Export data and import it with the RustaBase API.
- Turn queries and mutations into SQL, API calls, or RustaBase functions.
- Use realtime subscriptions where you relied on reactive queries.
