New: CheckVibe MCP server — scan from Claude Code and Cursor nativelyRead the docs
Detect exposed API keys, tokens, and secrets in your frontend code and responses.
Overview
Exposed API keys in client-side code are one of the most common and dangerous security mistakes in modern web applications. Our scanner analyzes JavaScript bundles, HTML source, and HTTP responses for leaked credentials including AWS keys, Stripe secret keys, database connection strings, and dozens of other secret patterns.
What this scanner does
Scans HTML source code, JavaScript bundles, and HTTP responses for patterns matching known API key formats. Detects AWS access keys, Stripe secret keys, GitHub tokens, database URIs, JWT secrets, and 30+ other credential patterns.
Why it matters
Exposed API keys give attackers direct access to your services — they can rack up cloud bills, access user data, send emails as your domain, or compromise your entire infrastructure. Vibe-coded apps are especially prone to this because AI assistants sometimes embed secrets directly in client-side code.
