Kingfisher
Kingfisher is a free tool for scanning for leaked secrets, checking whether credentials are live, mapping their blast radius, and supporting revocation for some credentials. It can scan files, directories, Git repositories and history, archives, SQLite databases, Python bytecode, Docker images, cloud storage, and developer platforms. Documented integrations include GitHub, GitLab, Azure Repos, Bitbucket, Gitea, Hugging Face, AWS S3, Google Cloud Storage, Docker, Jira, Confluence, Slack, Microsoft Teams, and Postman. The project describes a multithreaded Vectorscan engine and supports Betterleaks TOML and Kingfisher YAML rules. Reports can be human-readable or exported as TOON, JSON, JSONL, SARIF, BSON, or HTML. A local viewer can combine and deduplicate Kingfisher, SARIF, Gitleaks, and TruffleHog reports. Revocation is opt-in and depends on a supported provider workflow. Live validation and blast-radius mapping make provider API requests, which should only be used when authorized. Kingfisher runs on Linux, macOS, and Windows, and supports self-hosted use.
