Questions, answered

MIT licensed — commercial use allowed with attribution.

What server do I need?

Check the README for requirements — sandboxing needs a capable host.

Which AI models does the agent use?

See the repo docs for the supported providers.

Are the apps production-ready?

They are real apps, but review generated code before shipping.

How isolated are the sandboxes?

Isolation is the core design — verify against your security needs.
