Stop wasting time on half-baked bug reports.
Built by a former LangChain maintainer who got tired of spending hours triaging bug reports instead of shipping code.
Issue Envoy handles the repetitive, boring parts of triaging bug reports, so your team can spend more time building and less time asking for more information.
- No more asking for repros — automatically writes and runs reproduction code, so you know the bug is real
- Fewer abandoned issues — asks reporters for missing details quickly, while the problem is still fresh in their minds
- Better support for less engineering time — answers questions using your issue history and codebase
- One minute setup — just install the GitHub app and you're done

How it works
Issue opened
Someone files a bug on your repo.
Classified & triaged
Reads the issue, checks past issues for context, and asks the reporter for anything missing.
Reproduced in a sandbox
Clones your repo, writes a reproduction, and runs it in an isolated environment. Every action it takes is visible, so you can see exactly what happened.
Findings posted
Replies on the issue with its results and labels the bug as confirmed or not reproducible.
Pricing
per sandboxed investigation
Unlimited users. Unlimited repos. No additional fees. Cancel any time.
Issue classification, issue labeling, and issue search are all completely free. Your balance is only consumed when Issue Envoy spins up a sandbox to investigate an issue.
