Bring your own Claude Code
Your Claude Code subscription becomes the agent's brain, with the full JackHamr tool surface. Codex followed on July 6. In September it became fully managed.
A lot of the people who use JackHamr already pay for Claude Code. They like it. They have muscle memory for it. What they do not have is a way to run it on a real cloud machine, in parallel, with a review loop, without building a rack of mini PCs in a closet. Today they do.
Runtimes
A runtime lets your own Claude Code subscription drive a JackHamr agent. Install a small daemon on a machine you control, and JackHamr streams tasks to it. Your Claude Code operates the agent's container through an MCP bridge: the full tool surface, the agent's persona and skills, its memory, its browser. Output streams token by token back into the chat, exactly as it would in your terminal.
- Runtimes appear in the model picker with online and offline status and Opus or Sonnet variants
- Sub-agents and board cards can run on the runtime too, so a whole pipeline can use your subscription
- The daemon updates itself, and by July it handled twenty concurrent tasks
- OpenAI Codex support arrived on July 6 through the same mechanism
Why this matters
We are not precious about whose model does the thinking. What JackHamr provides is everything around the model: the machine, the tools, the memory, the parallelism, the reviewers, the board. If your favourite brain is Claude Code, bring it. You get the fleet infrastructure on top of the subscription you already have.
What came next
In September we removed the last bit of friction. Managed runtimes mean there is no daemon to host at all: the platform provisions the runtime host for you, you sign in from the browser, and it just works. But the idea started here, in June, with a small daemon and a big unlock.
More releases
Claude Code and Codex, no daemon
The platform now hosts the runtime for your Claude Code or Codex subscription. Nothing to keep awake. And you can steer a running turn mid-flight, like the terminal.
