What's Good
Apache-2.0 sync engine. Logical replication in, Shape partial replication out, CDN-friendly HTTP. Writes stay on your existing API. Self-host Docker; Cloud PAYG waives bills under $5/mo (~5M writes).
The Catch
Read-path sync — not a full offline-write CRDT stack or a replacement for your mutation API. Vs PowerSync/Replicache: Postgres-native shapes + free reads on Cloud, not mobile SQLite product packaging. Pro Cloud starts $249/mo.
Verdict
Apache-2.0 Postgres sync. Self-host free; Cloud hobby under $5 waived.
