I don't really understand what this is offering beyond Cloudflare's recent release of running SQLite in durable objects: https://blog.cloudflare.com/sqlite-in-durable-objects/. Is it about providing an external interface to Cloudflare's SQLite databases?
If that's the case there's libsql (https://github.com/tursodatabase/libsql) which already provides HTTP clients, embedded replicas (essentially good old SQLite but with replication support), self-hosted SQLite server and is maintained by a company using it for their own product.
iirc they are both powered by the same engine to stream and replicate the WAL. I believe R2 is now implemented as a Durable Object backed by SQLite now.
Still think there is a lot we can add to StarbaseDB to make the developer experience on SQLite databases better, and personally I think it starts with a better external interface. Provide a frictionless way to get started. Then figuring out how to improve developer experiences on how they interface with databases.
Is it auto-accessible REST endpoints? Easy to implement websocket support for the database? Data replication for scaling reads? Offline data syncing? A lot of potential wins for a layer like this to build on.
