Kanjin and Bugbot: your own agent, or Cursor’s.

Bugbot is Cursor’s reviewer for pull requests, and its fixes go to Cursor’s agents. Kanjin runs the agent that you already use on a Jira ticket, has it review and fix its change first, and makes the change shorter for you to read.

Bugbot Kanjin
When it reads the change On pull requests. In Cursor, /review-bugbot also reviews the changes of a branch before you push, uncommitted ones included. In the ticket’s worktrees, before the pull request exists, and again in the pull request review.
Who writes the review Bugbot, Cursor’s reviewer, with your team’s rules and BUGBOT.md files. Your own coding agent runs Review, Overengineer and Fix, signed in with your own plan. Then you review the change.
Where the result goes Comments that explain each issue and suggest a fix, a summary, and a CI status. The ticket session and the review in Kanjin. Kanjin never comments on a pull request.
How you read the change On the Git host, with its comments, or in Cursor. In Kanjin’s review: the blocks that preserve behavior fold, and every other change stays on screen, in the original code with its line numbers.
Fixes Autofix has a Cursor Cloud Agent push the fixes, and Fix in Cursor opens a finding in Cursor. Fix runs on your agent in the worktrees and checks each finding first. After a push, Fix Failures sends the failed GitHub checks and the open review threads to your agent.
Approval and merge Its CI check is neutral by default. With fail on unresolved issues, a required check can block the merge. Kanjin never approves a pull request, never merges one, and never labels a change safe to merge.
Git hosts GitHub, GitLab, Bitbucket and Azure DevOps. GitHub, GitLab and Bitbucket, and local folders on your Mac.

What Bugbot does

Bugbot reviews pull requests for bugs, security issues and code quality problems. It runs on GitHub, GitLab, Bitbucket and Azure DevOps, and comments on each issue with a suggested fix.

Its fixes go to Cursor: Autofix starts a Cursor Cloud Agent, and Fix in Cursor opens the finding in the editor. In Cursor 3.7 and later, /review-bugbot reviews a branch before you push.

What Kanjin does instead

Bugbot is Cursor’s reviewer, and its fixes go to Cursor’s agents. Kanjin runs the agent that you already use in a terminal, such as Claude Code, Codex or opencode, on a Jira ticket on your Mac.

Kanjin never comments on the pull request and never blocks it. Its own review folds the blocks that the classifier judges behavior-preserving.

Using both

Bugbot can review the pull request that Kanjin’s Commit & Push opens. On GitHub, the ticket in Kanjin shows the checks of the pull request, and Fix Failures sends the failed checks and the open review threads to your agent.

Questions

Is Kanjin a Bugbot alternative?

For a part of the work. Bugbot reviews pull requests and hands its fixes to Cursor. Kanjin has the agent that you already use review and fix its change before the pull request, and gives you a shorter diff to read.

Do I need Cursor?

No. Kanjin runs Claude Code, Codex, opencode or Gemini CLI, found through your login shell.
