The fix layer for production apps.

What we do

Most engineering teams already have a tool that tells them production is broken — Sentry, Datadog, Rollbar, the on-call page at 2am. bugstack is the tool that makes the broken thing stop being broken. Same capture pipeline, but the artifact at the end of the loop is a merged fix, not a Slack notification.

Our SDKs sit alongside your Express, Next.js, Flask, FastAPI, Django, Rails, or Go service. When an unhandled error lands, we read the stack trace, fetch the offending file from your GitHub repository, draft a surgical patch with frontier AI models, run it through your existing CI, and open a pull request. You review and merge — or, if you trust the CI signal, you let it auto-merge.

Why we built it

Developers spend roughly 30% of their time debugging — chasing a stack trace, opening the file, recreating local state, writing the same kind of fix they've written a hundred times before. Most of those fixes are mechanical. Null check here. Missing await there. Off-by-one. Misconfigured CORS header. The pattern of "human notices error, human writes one-line fix, human waits for CI" is the cheapest possible work to automate.

So we did. We didn't build another error-monitoring product. We built the layer that closes the loop.

How we operate

bugstack is built in public. We don't pretend to have customers we don't have, awards we didn't win, or social proof we haven't earned. Every claim on this site links to a source. Every benchmark is reproducible. Every fix that goes through our system is a real diff your team can review before it merges.
