Replicate App-Embedded DuckDBs into PostgreSQL with SyncLite OSS▲73
Hi HN, We have been building SyncLite, an open-source platform to simplify offline-first application development. If your application uses SQLite or DuckDB, SyncLite lets it continue using the local database as usual while synchronization happens in the background. For SQL-based applications, SyncLite records transactions into transactionally consistent .sqlog files using SQLite as an open replication format. A background consolidator replays those transactions, derives row-level CDC and schema changes, and applies them transactionally to destination databases like PostgreSQL. The same…

Sortabase, a collaborative, visual database builder for communities▲116
We built Sortabase to let communities collaborate on visual databases of the things they know and care about. The fields of each database are defined by its moderators using a no-code drag-n-drop interface, and the resulting database is easy to search, filter, sort, and contribute to. The platform is 100% free to use - take a look, and feedback is appreciated!
