About Archon
Archon is an open-source workflow engine for AI coding agents that lets you define your development processes as YAML workflows — planning, implementation, validation, code review, and PR creation — and run them reliably across all your projects. Like what Dockerfiles did for infrastructure and GitHub Actions did for CI/CD, Archon brings structure and repeatability to AI-assisted software development. It ships with 17 built-in workflows and supports custom workflows, making AI coding deterministic rather than dependent on model behavior.
- YAML Workflow Definitions — Define development phases, validation gates, and artifacts in
.archon/workflows/YAML files committed to your repo so the whole team runs the same process. - Isolated Git Worktrees — Every workflow run gets its own git worktree, enabling 5+ parallel fixes with no conflicts.
- Composable Nodes — Mix deterministic nodes (bash scripts, tests, git ops) with AI nodes (planning, code generation, review) so AI only runs where it adds value.
- Human-in-the-Loop Gates — Interactive loop nodes pause and wait for human approval before proceeding to the next phase.
- 17 Built-in Workflows — Includes
archon-fix-github-issue,archon-idea-to-pr,archon-smart-pr-review,archon-refactor-safely, and more out of the box. - Web Dashboard — A full web UI with chat interface, real-time workflow monitoring, drag-and-drop workflow builder, and unified inbox for all platform messages.
- Multi-Platform Adapters — Connect via CLI, Web UI, Slack, Telegram, Discord, or GitHub Webhooks; all conversations appear in one monitoring hub.
- Fire-and-Forget Execution — Kick off a workflow, go do other work, and come back to a finished PR with review comments.
- SQLite / PostgreSQL Backend — Stores codebases, conversations, sessions, workflow runs, isolation environments, messages, and workflow events across 7 tables.
- Quick Install — Install via
curl -fsSL https://archon.diy/install | bash(macOS/Linux), PowerShell script (Windows), or Homebrew; full setup wizard available viabun install+ Claude Code.
