The Verdict
These tools are fundamentally different. Claude Code Security uses AI reasoning to understand your code contextually. It can catch logic errors and explain why they're dangerous. VibeCheck uses pattern matching to catch the specific, known vulnerabilities that plague vibe-coded apps: hardcoded keys, missing RLS, exposed configs. They're complementary. Use Claude Code for deep reasoning about complex code logic. Use VibeCheck for a fast, deterministic check of the common security mistakes AI code generators make. If you don't have a Claude Code subscription, VibeCheck gives you security coverage at zero cost.
