PowerSync is built for offline use. Users can read synced data and make changes without a connection. The mutations wait in the upload queue, which survives app restarts, and upload when the client reconnects. See [Client Architecture](/architecture/client-architecture) for details.

With Neon Realtime, live query results stay available while the app is open, even if the connection drops. For offline persistence, Neon's documentation points to [TanStack DB](https://tanstack.com/db), which has its own persistence and offline write packages.

@Chriztiaan I can't find these docs. Do you know what the reference for this is?

| Client SDKs | Open source (Apache 2.0) | Open source (Apache 2.0) |
| Sync service | Source-available under FSL-1.1-ALv2. Each release becomes Apache 2.0 after two years. | Not open source. Neon has not published the source code of the live query engine or the Live SQL API. |

This feels like a massive differentiator and should probably be above the table
