Why we picked it Before you pay anyone for a full review, point SonarQube at the repository for a cheap, automated first read. It scans over 40 languages for bugs, security holes, duplicated code, and a technical debt estimate, so you get a rough health signal in an afternoon. It will not replace a human reviewer's judgment on architecture, but it is a solid starting point to see whether the inherited build is roughly clean or clearly rushed.
SonarQube
From SonarSource by Sonar (SonarSource) Tool, setup in an afternoon
- Automated static analysis flags bugs, security issues, and code smells without anyone running the code.
- It produces a technical debt estimate that gives a quick sense of how much cleanup the build needs.
- A free IDE version and self-hosted server option mean you can try it before spending on a paid review.
