Is it production-ready?

Two founders are running their own company on it (us). Design partners are using it in production. It is not v1.0 in the "five years of polish" sense. It is in the "we ship every day and you can read the changes on GitHub" sense.

Where are the agent autonomy bounds — can an agent act without my approval?

You choose. Agents are scoped to the objects, tools, and workspaces you grant them. Every read and write is a logged event you can inspect. Skills (the layer that defines agent behaviour) can require an explicit human @mention before high-stakes actions that's how our own setup works. Pause or stop any agent session from the UI at any time.

What about security and data privacy?

Self-hosted: your infrastructure, your rules, no data leaves your network. Managed cloud: EU-resident, no training on your data, retention only as you configure. Auth via standard OAuth providers. Every agent action is logged as an event on the object it touched fully auditable.
