Common reasons people leave Checkmarx: no published pricing or free tier, and heavier to roll out and tune than developer-first scanners. We ranked 7 alternatives by how directly each one replaces Checkmarx, then by reviews, real visits and how recently each app's facts were checked against its own website. SonarQube currently ranks first.
