Ok, really feels like I’ve crossed a milestone with Bartab 2.0 out.
• Firebase -> Supabase (so NoSQL to SQL AND moved auth)
• Synced local SQLite DB via PowerSync (everything feels so fast 🤩)
• Moved Vapor backend to free Render instance (and lessened dependency)

Our October & November product update is here! The feature story is our new TanStack DB Integration – you can now use TanStack DB collections on top of a PowerSync-backed SQLite store www.powersync.com/blog/powers...
PowerSync Changelog: November 2025
You might’ve noticed we skipped the October update – we were heads-down shipping a lot of stuff and a bunch of us attended Sync Conf in San Francisco. Feels like a good problem to have, but we also want to keep you in the loop, so here’s a stacked October+November edition to make up for it!

Facilitron is the "Airbnb for public spaces".
Their app needed a replacement sync solution when Atlas Device Sync + Realm was deprecated.
They turned to PowerSync and successfully migrated in a few months! 🔥

Local SQLite w/ PowerSync can speed up performance and improve UX of Electron apps.
But should PowerSync live in Electron's main or renderer process?
With both Node.js and web SDKs available, it's up to you!

Sync opens novel ways to use AI in apps.
E.g. not blocking UX with a "thinking..." state but instead asynchronously passing data to AI + RAG processes on the server & syncing the response when it's ready.
Loper uses this for its student-college matching app:
