Clang Static Analyzer vs CodeChecker
Both stand on c and c++ static analysis tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacWindows
Clang Static Analyzer offers free, self-hosted analysis for three languages, with command-line and potential IDE integration. Its limited detection scope, runtime, and possible false positives matter when interpreting results.

- May report false positives
- Detects only bugs it was engineered to find
CodeChecker: what it does well
- Supports analyzers for eight listed language groups.
- Reports can be filtered, compared, and reviewed in a web interface.
- Can limit reanalysis to changed files and dependencies.
- Local server or Docker deployment is available.
What to know first
