Secretlint is an open-source, pluggable command-line tool for scanning project files for credentials and other exposed secret data. It is suited to JavaScript-oriented linting workflows and teams that want secret checks close to development, including pre-commit hooks, continuous-integration pipelines, and pull requests. The tool runs through Node.js, Docker, or downloadable single-executable binaries, and a Chrome extension can detect credentials in web requests and responses.

The project is distributed under the MIT license and has a free open-source plan rather than tiered paid editions. Its integrations include GitHub Actions, Husky, lint-staged, pre-commit, and Mega-Linter. GitHub Actions formatting can add pull-request annotations, while output options include JSON, SARIF, and GitHub annotations. Glob-based scanning, ignore-file support, secret masking, configurable rule packages, and custom rule creation give teams control over which files and patterns are checked.

Secretlint fits teams that prefer configurable linting within existing Git and GitHub Actions processes. Its category coverage is narrower for organizations seeking dedicated server-side protection: supported VCS coverage is Git, and push protection is not provided. Teams that need checks enforced at the repository hosting boundary, or coverage beyond Git, should choose a tool with those capabilities instead. For developer-led scanning before commits and CI reporting, Secretlint offers a focused open-source option with a customizable rule model.

  • Where it doesn't
    • Verified VCS coverage is limited to Git.
    • It does not provide dedicated push protection.
    • Configuration and rule selection require developer workflow setup.
