Best alternatives to KeySentry in 2026
Committing a secret to a public GitHub repo happens more often than teams like to admit — a stray .env file, a hardcoded AWS key, an SSH private key copied in by mistake. KeySentry scans a GitHub repo or a local folder for over 25 common API key formats (AWS, Slack, Stripe, OpenAI, and others), using both regex pattern matching and entropy analysis to catch keys that don't match a known format but still look random enough to be a real secret. It also flags sensitive files by name, like .env, id_rsa, or firebase.json. It's free and open source under the MIT license, usable via a command-line interface or a web-based frontend hosted on Netlify, with Docker support for teams that want it in a container. It outputs structured JSON for piping into other tools and ships with YARA detection rules for more advanced pattern matching.
