Env Leak Detector — Free Developer Utility

Env Leak Detector scans pasted code, configuration files, or .env content for patterns that match common secret formats — API keys, passwords, AWS credentials, Stripe keys, GitHub tokens, Slack tokens, and database connection strings with embedded passwords. Accidentally committing secrets to a public repository is one of the most common and costly security mistakes developers make; automated bots scan GitHub continuously for exposed keys within minutes of a push. This tool uses pattern matching against known credential formats (like AWS access keys starting with AKIA, or Stripe secret keys starting with sk_live_) to flag likely leaks before you commit, share, or paste code into a public forum, ticket, or chat. Each finding shows the line number, the type of secret detected, and a severity rating.

Frequently Asked Questions

No, scanning happens entirely on the server for that single request and nothing is logged or retained — your code is processed and immediately discarded.

It catches common, well-known patterns (AWS keys, Stripe keys, GitHub tokens, generic password/API key assignments). Custom or unusual secret formats may not match and require manual review.

Immediately rotate/revoke that credential at its source (AWS console, Stripe dashboard, etc.) — even if you remove it from code, it may already be exposed in git history or logs.

This tool is designed for pasting individual files or snippets. For scanning entire repositories automatically, dedicated tools like git-secrets or TruffleHog integrated into CI/CD are more appropriate.
