Cursor Bugbot is an AI code review service from the makers of the Cursor editor. Once enabled, it runs automatically in the background on new GitHub pull requests, comments on likely bugs and proposes fixes that can be applied in Cursor or handed to a Background Agent. It focuses on hard logic bugs and aims for a low false-positive rate. Bugbot is included in Cursor's Teams plan at $40 per user per month, and the Pro plan at $20 per month offers it on usage-based billing.
Engineering teams that make pull request review a required step before merging are the main audience, from small startups to larger organizations with many contributors. Reviewers who face long diffs get summaries that describe the actual code changes, which helps with large merge requests. Teams that ship a lot of AI-generated code can add an automated second check, and engineering leaders can write Bugbot Rules to enforce coding standards and project-specific guidelines across repositories. A 14-day free trial covers all plans.
A typical flow starts when a developer opens a pull request: Bugbot reviews it, posts inline comments such as a shared default options object being mutated or a timestamp unit mismatch in token validation, and the author applies the fix. Because it looks beyond the touched lines, it can catch problems in how a change interacts with existing components and assumptions elsewhere in the codebase. It works as a pre-merge check alongside integration and smoke tests in CI, and testimonials describe it catching implementation errors after human approval. More than 70 percent of its flags are resolved before merge.
