SQLSync is a collaborative offline-first wrapper around SQLite designed to synchronize web application state between users, devices, and the edge.

Example use cases

• A web app with a structured file oriented data model like Figma. Each file could be a SQLSync database, enabling real-time local first collaboration and presence
• Running SQLSync on the edge with high tolerance for unreliable network conditions
• Enabling optimistic mutations on SQLite read replicas

SQLSync Demo

The best way to get a feel for how SQLSync behaves is to play with the Todo list demo. Clicking this link will create a unique to-do list and redirect you to its unique URL. You can then share that URL with friends or open it on multiple devices (or browsers) to see the power of offline-first collaborative SQLite.

You can also learn more about SQLSync and it's goals by watching Carl's WasmCon 2023 talk. The recording can be found here.
