Common questions
Is the SDK really free?
Yes. The TypeScript, Python, Go, and Java SDKs are MIT-licensed and free forever. You only pay if you want Aroha-managed cloud infrastructure.
What counts as a 'hosted agent'?
An agent deployed through Aroha Studio and served from our managed infrastructure. Agents you self-host on your own servers don't count against any limit.
Can I self-host everything?
Yes. The registry server, identity service, and audit log are all open-source. Enterprise customers can run the full stack on their own infrastructure.
