DiffSentry

DiffSentry is a developer tool that reviews code changes at the diff level and flags high-risk edits before they merge. Instead of generic “AI code review,” it focuses on the stuff that actually causes incidents: auth/permission changes, query shape changes, missing migrations, config toggles, logging/PII leaks, and silent behavior changes in edge cases. It runs as a GitHub/GitLab app plus a small web dashboard, producing a short “risk report” on every PR with a clear rationale and links to the exact hunks. Teams can define policies (e.g., any change touching billing requires two approvals; any new endpoint must include rate limiting notes) and enforce them in CI. It also learns from your postmortems by letting you tag past incidents and mapping them to patterns in future diffs. The goal is fewer regressions, not prettier code.
