If you'd be open to trying something else, my startup is open core: https://github.com/gofixpoint/amika

The definition for your cloud sandboxes is just a TOML config in your repo

We also have an API and CLI to let users message the agent from outside or across sandboxes

We're still building a lot, so if you have any time to try it out (amika.dev) and give feedback, that is worth gold to us!
