OpenHermit

Agents, but operable.

Open-source platform for deploying fleets of AI agents as production services — durable state, sandboxed execution, managed at scale, and the channels you already use.

Built by Amiko — an agent-agnostic infrastructure platform for the AI era.

Why OpenHermit

Most CLI-based agents (Claude Code, OpenClaw, Hermes, …) keep their state in files: memories as markdown, sessions as JSONL, skills as folders, secrets as dotfiles. That's perfect for one human at one machine — but it falls apart the moment you stop being one human. Running an internal agent platform for your team, a SaaS where every customer gets their own agent, or a swarm of specialized roles? Files scatter, secrets leak, fleet operations turn into SSH-and-pray.

OpenHermit makes one core design choice: separate internal state from external state.

• Internal state — sessions, memories, instructions, skills, MCP servers, schedules, secrets, users — lives in shared PostgreSQL, scoped by agent_id.
• External state — the workspace files an agent is currently working on — lives in a per-agent sandbox. Pick the backend that fits your deployment: a self-hosted Docker container, or a cloud sandbox provider like E2B or Daytona.

Once internal state is centralized, fleet operations become trivial:

hermit skills enable standup-digest --all                       # roll a skill out to every agent
hermit mcp enable mcp_github --all                              # add an MCP server to every agent
hermit instructions append rules "Never share PII." --all       # push a rule to every agent
hermit config secrets set OPENROUTER_API_KEY sk-... --agent main  # rotate a secret
