About Hezo – Self-hosted teams of AI agents that never see your real secrets
Hezo is a self-hosted platform for creating teams of AI agents that coordinate to complete tasks. It features a meta-harness with roles like CEO, captain, and worker agents that plan, edit, and review work. Agents never see real secrets due to a proxy system with AES-256-GCM encryption and Docker isolation. Users can set budgets per model, review work in real-time chat, and reuse skills. It works with providers like Anthropic, OpenAI, Google, and more. Setup is via a single curl command.

FAQ
Do I need to host my own models?
No — bring API keys or subscriptions for the providers you want. Hezo runs the agents; the models stay with them.
Can agents see my API keys?
No. Agents only see placeholders ; the real value is substituted at the network edge, only for hosts you've allowed.
How is Hezo secured?
Secrets are encrypted at rest (AES-256-GCM) behind a master key only you hold, every agent runs in an isolated Docker container, and all agent traffic passes through the egress proxy.
Is my data sent anywhere?
Hezo is self-hosted. Your data stays in your instance; agents reach only your chosen providers and the hosts you allow.
Can I run multiple projects?
Yes — each gets its own team and isolated container. Up and running in one command.
