Open source XBOW alternative: self hosted, local, auditable

XBOW made autonomous AI pentesting famous, but it is closed, cloud hosted and enterprise priced. Here is the open source, self hosted, local-LLM path, with a reproducible OWASP Juice Shop benchmark.

XBOW made autonomous AI pentesting famous by topping a public bug-bounty leaderboard. It is also closed, cloud-hosted and priced for enterprises. If you want the same idea but open source, self-hosted and local, here is the honest path.

Why teams look past XBOW

  • Data sovereignty. XBOW is a vendor cloud; your targets and traffic transit it. Darkmoon runs on your infrastructure and can use a local LLM, so nothing leaves.
  • Auditability. XBOW is a black box. Darkmoon is GPL-3.0, read and modify the methodology.
  • Cost. No enterprise contract; clone and run.

Does open source actually find things?

Yes, measurably: Darkmoon found 57 real vulnerabilities on OWASP Juice Shop in 28 minutes, black-box, local model, exploit-proven per finding, published and reproducible in the open AI-pentester benchmark. The point is not to claim a number nobody can check; it is to publish one anyone can.

Full disclosure: Darkmoon is our project. github.com/ASCIT31/Dark-Moon.

Run it against your own lab

Darkmoon is open source (GPL-3.0) and self hosted. Clone it, point it at a target you own, and read every line.
