Vibe-code Security Checker alternatives

Vibe-code Security Checker is a free prompt. A review prompt for vibe-coded diffs. It hunts secrets, missing auth, injection, and insecure defaults, then names the fix.

It is not always the right tool. Here is when something else wins, and when it does not.

  1. Dedicated tool

    Snyk, Semgrep, or GitHub code scanning

    Pick it if
    You want automated scanning on every commit.
    Pick Vibe-code Security Checker if
    You want a readable review of one diff in your editor, free, with the fix written out.

  2. By hand

    OWASP checklist by hand

    Pick it if
    You know security well and have time.
    Pick Vibe-code Security Checker if
    You do not, and the feature ships today.

Where it falls short

It is not a penetration test and it refuses to write exploits. It names the risk and the fix.
