Archon vs sdk-go
Archon has 23,505 GitHub stars, 3,474 forks, 321 open issues and last shipped 2 days ago. sdk-go has 970 stars, 351 forks, 229 open issues and last shipped 2 days ago. Archon leads on adoption by 2,323% (23,505 vs 970 stars). Archon is written in TypeScript under MIT; sdk-go is written in Go under MIT. Archon has attracted 15% as many forks as stars, sdk-go 36%. sdk-go was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (workflow-engine), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

About Archon
Archon is an open source workflow engine for AI coding agents, written in TypeScript and released under the MIT license. It lives in the AI coding ecosystem, alongside tools such as Claude Code, and is distributed through the Bun runtime and the GitHub CLI. The project describes itself as a harness builder: it lets a developer encode a development process as a YAML workflow and then run that workflow reliably across projects. Workflows are stored in a .archon/workflows/ directory and committed to the repository, so the same definition can be invoked from the CLI, a web UI, Slack, Telegram, or GitHub.…
