Best alternatives to KeyLeak Detector in 2026
It's surprisingly common for a secret key — for OpenAI, Stripe, AWS, a database — to end up exposed in a website's public JavaScript files, HTTP headers, or API responses, usually by accident during development. KeyLeak Detector scans a live site the way an attacker would: it crawls pages, inspects JS bundles, network traffic, and headers, and checks whether any exposed key is actually still active, rather than just pattern-matching text and guessing. It supports live validation across 14+ providers (OpenAI, Anthropic, Gemini, Stripe, GitHub, AWS, and more), checks Supabase and Firebase projects specifically for missing Row-Level Security, analyzes JWT tokens for risky permissions and expiry issues, and can discover and scan an entire site's subdomains at once. It ships as a Chrome extension, a Python CLI, and a GitHub Action, keeps false positives down with a 200+ domain allowlist, and — notably — runs entirely locally with zero data sent anywhere.
