What is Archon?

Archon addresses a common problem with coding agents: the result depends on the run, and an agent may skip the plan or forget the tests. You describe how work should be done as YAML workflows that combine AI agents, scripts and decision points for you, and Archon runs them, with queues to keep work moving. A bundled pack for the software lifecycle takes an issue all the way to a merged pull request, and the same engine can run any process you can describe.

Good fit if

  • You want repeatable, reviewable agent runs instead of one-off chats.
  • You want to step in only when a decision is yours to make.

Look elsewhere if

  • You want an interactive agent in your terminal: OpenCode.
  • You want to run many agents in parallel on one task: Orca.

Before you adopt it

Archon moved from a proprietary community license to MIT in April 2026, so it is now open source. Its creator, Cole Medin, writes nearly all of the code.
