Replicache

Client-side sync framework for realtime, local-first web apps, now in maintenance mode

Aboutreplicache.dev

Replicache is a client-side datastore and sync framework for realtime, collaborative web apps with instant interfaces. It works with most backend stacks. Rocicorp moved it to maintenance mode, made the code open source, and stopped charging for it. The team now focuses on Zero.

For an agent

Use it to learn local-first sync, or for an app that already runs on it. For new projects, check Zero first.

Why it is here. It shaped the local-first approach to instant interfaces.
