Frequently Asked Questions

Is SyncForge a free Firebase alternative?

Yes, SyncForge is an elite local-first free alternative to Firebase and Supabase. By shifting compute and storage to the client, you save drastically on cloud costs while providing a superior, instant UI experience.

How does conflict resolution work?

SyncForge utilizes state-of-the-art CRDTs (Conflict-free Replicated Data Types). When two clients modify the same data offline, the mathematical properties of CRDTs ensure that once they sync, both clients will converge to the exact same state without arbitrary "last-write-wins" data loss.
