CodeQL alternatives: 3 apps ranked by verified data

Facts checked Nov 1, 2026AppBreakup editorialHow we rank

Common reasons people leave CodeQL: private, commercial use requires a paid GitHub Code Security licence, and QL query language takes real effort to learn. We ranked 3 alternatives by how directly each one replaces CodeQL, then by reviews, real visits and how recently each app's facts were checked against its own website. Semgrep currently ranks first.

    • Open-source CLI runs anywhere, including locally
    • Free edition covers small teams on the hosted platform
    • SAST, dependency and secrets scanning in one product

    • Free edition is capped at 10 contributors
    • Paid products are billed separately per contributor
