Hi everyone!!! I'm qmxcu, the maintainer of ghost-hunter, an AI-powered bug reproduction tool

Hey everyone! I'm qxmcu, a solo developer and student just shipped my first real open-source project: Ghost Hunter, an AI-powered bug reproduction tool for GitHub.

The problem: someone files a bug report, and half the time is spent just trying to reproduce it before you can even start fixing anything. Ghost Hunter automates that comment bot/reproduce on an issue, and it parses the report with an LLM, spins up an isolated Docker sandbox, actually runs the repro steps, and posts the crash logs back automatically.

It's fully open-source, self-hosted, and I've been genuinely grateful for the security feedback the community already gave me pre-launch fixed what came up rather than shipping around it. Would love for you to check it out, break it, or just tell me what you think: Link to the repo!

Launching on Product Hunt today if you want to follow along!

Ghost Hunter - Turn bug reports into reproduced crashes, automatically.

Ghost Hunter isn't the first AI bug-reproduction tool, similar internal systems exist at companies like Metabase, who deliberately gate them behind human review to prevent prompt injection from public issues. What's different here: Ghost Hunter is fully open-source and self-hosted rather than a proprietary internal tool, works with any GitHub repo with no custom infra, and has had real security measures implemented based on community feedback, not hidden limitations, but ones actively addressed.
