Best security scanner for Cursor

Cursor doesn't host for you, so there's no single platform with one typical hole — there's your repository and your deploy. The most common mistake isn't in the code Cursor wrote, it's in the ignore list: .cursorrules, .specstory/ and .env slip into the production build.

Ranking: 1. Grove Vibe Check (targets public /.cursorrules and /.specstory/, checks bundle and source maps), 2. Semgrep (custom rules for the antipattern your AI keeps repeating), 3. Snyk (findings right in the editor), 4. Aikido Security (secrets in git history), 5. CheckVibe. For an editor the right answer is a combination of two layers, not one winner.
