Breakspec vs Cursor Bugbot
Bugbot is Cursor’s pull request reviewer. It looks for bugs, can fix them, and learns rules from how your team reacts to its comments. Breakspec’s rules work differently: a person approves each one, and Breakspec checks it by running your code.
What Cursor Bugbot does
- Since May 2026, Bugbot is billed per run. Cursor says an average run costs $1.00 to $1.50.
- It learns rules from reactions and replies to its comments, and from your reviewers’ comments. Rules that prove useful switch on automatically.
- Autofix suggests fixes for the serious problems it finds.
How Breakspec is different
Nothing switches on by itself
Your agent can suggest rules, but they wait for a person to approve them. Until then they can warn you, but never block a merge.
Not tied to Cursor
Breakspec checks code from Claude Code, Codex, Cursor or a person.
| Cursor Bugbot | Breakspec | |
|---|---|---|
| How it finds bugs | An AI reads the change | Runs your code on hundreds of examples |
| What you get back | A comment about what might be wrong | An example that breaks your code, which you can run yourself |
| Who decides what “correct” means | The AI, guided by your instructions | You, by approving rules |
| Cost of checking every pull request | About $1.00 to $1.50 per run, by Cursor’s figures | No AI cost. Rechecking doesn’t use AI |
| After a fix | Reviews the new code again | Reruns the example that failed, and notices if the fix cheats |
What Cursor Bugbot does better
- If your team works in Cursor, it’s right there, and it fixes things in the same place.
- It reviews the whole change, including code no rule covers.
Can I use both?
Yes. Bugbot catches what looks wrong. Breakspec checks what your rules say must always be true, and then checks the fix.
