ggshield vs Kingfisher

ggshield is GitGuardian’s command-line tool for finding hardcoded secrets before code is pushed. It can scan local files and repositories, run before commits or in CI pipelines, and act as a pre-receive hook for self-managed version control. It also scans Docker image layers, build arguments, and Dockerfiles. GitGuardian’s documentation describes detection for more than 600 secret types. The open-source CLI uses a closed-source secrets detection library behind GitGuardian’s public API. It runs on macOS, Linux, and Windows, with API and self-hosted options. Standard installation needs Git and a supported, non-end-of-life Python version; standalone packages are an exception. Scans require an API key for a GitGuardian workspace, and the login command can provision and store a personal access token. Files over 1 MB are ignored, and API calls accept up to 20 documents each. The free Starter plan is free, billed Always; it includes up to 25 developers, 10K API calls per month, up to 500 historical scan detections, and unlimited real-time scanning.

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.
