Cursor Bugbot
Cursor’s production reviewer: bug-first, not style-first, and wired back into the Cursor editor the team already switched to.
Best for
- Teams already on Cursor who want a PR gate without a second vendor
- Repos where logic bugs matter more than nits
Watch out
Not a substitute for choosing Cursor the editor — that comparison lives under /ai-harnesses. Usage billing means a busy repo can outrun a flat-seat mental model; size spend from cursor.com/pricing#bugbot, not from a third-party $/run table. Requiring the Bugbot check without fail-on-unresolved-issues still allows merge when findings are posted.
GitHub Copilot code review
The default if the team already pays for Copilot: no second GitHub App, no second vendor review.
Best for
- Teams standardised on GitHub Copilot
- Orgs that want review coverage on every PR without a seat for every author
Watch out
Shares credit pools with the rest of Copilot. Unlicensed-author coverage is policy-gated and bills AI Credits plus Actions minutes. Azure DevOps support is public preview. Buying a dedicated reviewer only pays if Copilot’s native review is too shallow for the repo.
