HasMySecretLeaked helps developers check if their secrets (API keys, credentials) have been compromised by searching across 20+ million leaks in public GitHub repositories, gists, and issues.
The GitGuardian Shield is an Open Source application to help you detect more than 200 types of secrets. Those include API keys, database credentials, certificates, as well as other potential security vulnerabilities or policy breaks. Support the project by starring the repository on GitHub.
