Your rules, not general ones
No general rule set knows that the shares of a bill must add up to the bill. Breakspec checks the rules you approved for your function.

Breakspec vs SonarQube
SonarQube reads your code without running it, and checks it against a large set of general rules for bugs, messy code and security problems. Its AI Code Assurance adds stricter checks for projects that contain AI-written code. What it can’t know is what your function is supposed to do.
What SonarQube does
- Checks code in many languages, and can pass or fail a pull request.
- AI Code Assurance labels projects that contain AI-generated code and applies stricter checks to them.
How Breakspec is different
It runs the code
SonarQube reads your code. Breakspec runs it, and shows you an input that gives the wrong answer.
| SonarQube | Breakspec | |
|---|---|---|
| How it checks | Reads your code against general rules | Runs your code against your rules |
| Knows what your function should do | No | Yes, from the rules you approved |
| What a finding looks like | A warning on a line of code | An input, and the wrong answer your code gave |
| Can fail a pull request | Yes | Yes |
What SonarQube does better
- It covers security, maintainability and duplicated code across your whole codebase.
- It’s mature, widely used, and familiar to security teams.
Can I use both?
Yes. Keep SonarQube for code quality and security, and add Breakspec to check the logic is right.
