About Kenji Watanabe
Local-first software is mostly a sync problem wearing a UX costume.
Driftwood
Driftwood is a sync engine you can drop into an existing app without rewriting your data model. It handles the boring, load-bearing parts: offline queues, conflict resolution, schema migration across versions that are live simultaneously.
Why open source
Sync is infrastructure. Infrastructure that you cannot read is infrastructure you cannot trust, and I would not adopt this if someone else had built it as a closed service.
