About Vaicoa

Vaicoa runs production on servers you own and makes twins of it, where people and coding agents work instead. One hub, one Go binary with one SQLite file, runs in your own cloud project; an agent on each server keeps it on the release and settings the hub holds. It is in a closed alpha today and open source under Apache-2.0 from the launch, planned for February 2027.

Own your platform: the servers, the cloud account, the tokens and the data are yours, and from the launch so is the source code.
