Cursor BugBot
AI PR Review · #13 of 20 in category · #19 of 27 overall
Cursor's PR reviewer scoped to bugs, security issues, and rule violations, billed per run (avg $1.00-1.50) since June 2026.
[ Where it fits ]
On the documented evidence, Cursor BugBot suits teams already standardised on GitHub and GitLab.
[ Documented strengths ]
- Rule-Centric & Default Quiet. Path-scoped .cursor/BUGBOT.md rules plus org-wide team rules; deliberately quiet, bug-only scope.
[ Documented gaps ]
- Dual-Workflow: Local vs. PR. PR-only reviewer; 'Fix in Cursor' hands findings to the editor, but there is no local review mode.
- Business Logic Validation. No ticket or process integrations - deliberately out of scope.
- Sandbox Validation. No documented sandbox execution or test generation; static diff analysis with effort levels.
- Economic Transparency. No BYOK or model pinning; per-run cost (~$1.00-1.50) is visible but models are Cursor-selected.
