About bugzero
An AI agent that analyzes production errors from Sentry and opens GitHub pull requests with fixes, automatically. Connect GitHub and Sentry in about two minutes, OAuth and a GitHub App, no webhook wrangling. The agent analyzes the error and shows the fix it would make, but opens no PR until you approve it.
