Free, Open Source

Realtime Collaboration

Users see each others’ changes live, as they happen. No refreshes, no locking.

Instant UI

The UI responds instantly, with no server roundtrips. All reads and writes are “optimistic” by default.

Robust Offline Support

Applications can go offline for hours or days and sync up smoothly when they come back online.

Bring Your Own Backend

Your data stays on your servers. Replicache is client-side technology and works with many backend stacks.

Transactional conflict resolution

Replicache uses server-authoritative rollback netcode to resolve conflicts. It's an intuitive and powerful technique used for decades in the game industry.

It Just Works

Conflicts, tabs, schema migrations – Replicache handles all the hard parts. You'll find it's even more productive than traditional web frameworks.

Replicache is free to use for non-commercial projects, and for companies with < $200k annual revenue and < $500k in funding.

For other commercial projects, the first two months are free, and then we charge based on the number of monthly active profiles.
