Comparison
Vezraa vs Semgrep
Semgrep is a fast, open-source static analyzer — it reads your source code and flags patterns that look insecure. Vezraa works from the other end: it never sees your code. It scans the live deployed app by URL, attacks it the way a real user or attacker would, and shows you the exact request that got through. Static analysis tells you what might be exploitable; Vezraa proves what is.
Static vs dynamic
Semgrep reasons about code paths that could be reached. It can't know if your Supabase RLS is actually open, if your webhook signature is really being verified in production, or if a secret made it into the shipped JS bundle. Vezraa checks the running app, so those answers are facts, not guesses.
Zero setup
Semgrep needs your repo, a config, and often custom rules to catch app-specific issues. Vezraa needs only the URL you already deployed — and it ships the vibe-coding checks (RLS, payments, AI cost) out of the box, with no rules to write.
When to use which
Use Semgrep when you want to catch insecure patterns in code review and block them in CI across many repos — especially with custom rules for your own conventions.
Use Vezraa when you've shipped an AI-built app and need proof of what's actually exploitable in production — live exploit replay, Supabase and payment checks, and paste-ready fixes for Cursor or Claude. Many teams run both: Semgrep in CI, Vezraa on the deploy.
