SemgrepvsSonarQube

Semgrep focuses on static code and supply-chain security. Semgrep is especially attractive when a team wants to encode its own secure coding rules. That flexibility makes it useful for catching organization-specific mistakes that generic scanners may overlook. Poorly tuned rules can produce a stream of low-value findings. Someone needs to maintain the ruleset as frameworks and internal coding conventions change.

SonarQube focuses on code quality and security analysis. SonarQube gives teams a shared definition of code health through quality gates, duplication metrics and maintainability findings. It is useful when pull requests need consistent standards. A passing quality gate does not guarantee secure or well-designed software. Overly strict defaults can also encourage teams to chase metrics rather than fix meaningful problems.
