triplit
Triplit is an open-source, full-stack database that syncs data between server and browser in real-time. It handles client-side caching, server-side storage, and automatic conflict resolution using CRDTs, with support for offline mode and optimistic updates across React, Vue, Svelte, and other frameworks.

What triplit is
Triplit is a TypeScript monorepo providing a CRDT-based syncing database with pluggable storage backends (SQLite, IndexedDB, LevelDB), WebSocket-based sync protocol, relational querying, schema validation, server-side authorization enforcement, and framework-specific bindings. It runs on both client (browser, React Native, Deno) and server (Node.js, Cloudflare Workers, Durable Objects).

Best use cases
Implementation considerations
- Schema definition and TypeScript autocompletion are core; invest time upfront in schema design and migrations (CLI tooling available).
- Requires running a Triplit sync server (Node.js or Cloudflare Workers/Durable Objects); DevOps effort depends on chosen deployment target and HA requirements.
- CRDT-based conflict resolution works at property level; understand merge semantics for your domain to avoid unexpected data outcomes.
- Client-side storage is pluggable (IndexedDB, SQLite, etc.); choose backend based on target platform (browser vs. React Native) and storage quota constraints.
- Authorization rules are server-enforced; incorrect rule configuration can expose data; manual security review strongly advised.
When to avoid it — and what to weigh
- Strict proprietary/closed-source requirement — AGPL-3.0 license requires source disclosure for any networked service; closed-source commercial deployments need explicit legal review or commercial license (if available).
- High-security/compliance-first environment — No evidence of formal security audit, penetration testing, or compliance certifications (SOC2, HIPAA, etc.) documented in the data. Authorization is enforced server-side, but overall security posture requires review.
- Simple CRUD with minimal sync needs — Over-engineered for read-heavy or loosely-coupled systems; standard REST APIs or traditional databases may be simpler and have lower operational overhead.
- Mature enterprise support contracts expected — Community-driven project with no evidence of commercial SLA, guaranteed response times, or dedicated support tiers; best for teams comfortable with async Discord support.
License & commercial use
AGPL-3.0 (GNU Affero General Public License v3.0). This is a copyleft license requiring source code disclosure for any networked service using Triplit. Internal use and modifications for private deployment do not trigger disclosure, but offering Triplit-powered services over a network (SaaS) requires making all source (including custom code) publicly available under AGPL-3.0.
AGPL-3.0 is not a permissive OSI license for commercial networked services without disclosure. Private, internal use (e.g., enterprise desktop app, private API) is permitted. Commercial SaaS or cloud offerings built on Triplit require either: (1) releasing all source code under AGPL-3.0, or (2) obtaining a separate commercial license from Aspen Cloud (if available—not documented in provided data). Legal review strongly recommended before commercial deployment.

Server-side authorization enforcement is present; rules must be carefully configured to prevent data leaks. No mention of formal security audit, penetration testing, or vulnerability disclosure program in provided data. CRDT-based conflict resolution means understanding edge cases in merge behavior is important for data integrity. WebSocket communication should use TLS/WSS in production. Requires security review before handling sensitive or compliance-regulated data.
Alternatives to consider
Firebase Realtime Database / Firestore
Proprietary, fully managed, battle-tested at scale; no self-hosting or AGPL licensing concerns, but higher cost, vendor lock-in, and less control over sync logic.
Supabase (PostgreSQL + Realtime)
Open-source alternative with PostgreSQL backend; simpler schema, mature ecosystem, but less first-class support for offline-first and CRDTs; better fit for server-centric architectures.
RxDB
JavaScript-native CRDT-like syncing library; lighter-weight, no separate server required, but requires more manual sync logic configuration and less framework integration than Triplit.
