Triplit is an open-source database that syncs data between server and browser in real-time.

Triplit provides a real-time syncing datastore that you can drop into your app as a Typescript package. Triplit handles storing your data on the server and intelligently syncs your queries to your clients. We call this type of system a “full stack database”—you can watch our presentation to the Local First community on this new paradigm here.

Triplit brings together:

🔄 Real-time sync with incremental updates and conflict resolution at the property level

🏠 Local caching powered by a full-fledged client-side database

💽 Durable server-side storage with an admin dashboard

🔌 Pluggable storage providers like SQLite, IndexedDB, LevelDB, Memory, etc

😃 Optimistic updates to make every interaction feel fast

🔗 Relational querying for complex data models

🛫 Offline-mode with automatic reconnection and consistency guarantees

🔙 Rollback and retry management on failed updates

🗂️ Schemas for data safety and Typescript autocompletion

🔐 Authorization that's enforced on the server for both read and writes

🤝 Collaboration/Multiplayer powered by CRDTs

🏎️ Low latency with minimal network traffic using delta patches

📝 Simple API for querying and mutating data in both vanilla Javascript and React

✅ Fully open-source!
