Triplit
Local-first database with built-in sync. Triplit stores data locally in the browser (IndexedDB) and syncs it to a Triplit server in real-time. Applications work offline by default — sync happens when connected. TypeScript-first schema with React hooks. Positioned between Replicache (complex) and ElectricSQL (Postgres-centric) — Triplit is a standalone local-first database with its own query engine.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Token-based access control. Local data stored in browser IndexedDB — consider encryption for sensitive data. Apache 2.0 licensed.
⚡ Reliability
Best When
You're building a collaborative or offline-capable web app where local-first architecture eliminates loading spinners and enables offline use.
Avoid When
You need complex SQL analytics, large data volumes, or don't need offline/real-time sync — a traditional server-side database is simpler.
Use Cases
- • Build collaborative applications (shared documents, kanban boards) that work offline and sync in real-time when connected
- • Create React applications with local-first data that requires no loading states — data is always available locally
- • Build multi-user applications where all users see changes in real-time without custom WebSocket sync logic
- • Implement offline-capable agent frontends that queue actions locally and sync to server when connectivity returns
- • Build instant-responsive UIs where reads are from local store and sync is eventual
Not For
- • Applications requiring PostgreSQL-compatible queries — Triplit has its own query engine, not SQL
- • Large datasets (millions of rows per user) — local-first databases are optimized for user-scale data, not analytics-scale
- • Server-only backends — Triplit's value is the local-first sync architecture
Interface
Authentication
Token-based auth. JWT tokens passed to TriplitClient for user identity. Self-hosted Triplit server or Triplit Cloud.
Pricing
Apache 2.0 licensed open source core. Triplit Cloud is the managed service.
Agent Metadata
Known Gotchas
- ⚠ Triplit is 0.x semver — API changes between minor versions; pin versions and read changelog before upgrading
- ⚠ Schema changes require migration strategy — Triplit doesn't have automatic schema migrations; changing entity definitions may require data migration
- ⚠ Local-first means data is on the client — for server-side agent processing, use Triplit's server-side client, not the browser SDK
- ⚠ Auth tokens must encode user permissions — Triplit's access control is token-based; server validates tokens to scope data access
- ⚠ Triplit queries are reactive by default — data changes update subscriptions automatically; understand subscription lifecycle to avoid memory leaks
- ⚠ Offline mutations queue locally — if conflict resolution isn't implemented carefully, conflicting offline edits may overwrite each other on sync
