hk review
An open-source, CI-ready hook manager with broad lifecycle and monorepo coverage.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
hk is an open-source Git hook manager and project linting tool written in Rust. It targets solo developers through enterprise teams that need shared, repeatable checks across repositories. The tool handles pre-commit, pre-push, commit-message, checkout, merge, rewrite, rebase and other Git events. A committed hk.pkl file lets teams share repository configuration, while built-in linter and formatter definitions cover common step setup. Cross-platform support spans Windows, macOS and Linux.
The published model is open source under the MIT license, with a free plan and no paid tiers. Installation options include mise, Homebrew, Cargo and prebuilt binaries. Its ecosystem connections include Git, Pkl, mise, Homebrew and Cargo, giving teams several ways to fit hk into existing toolchains. For CI, hk can run full-repository or changed-file checks and emit structured JSON or JSONL diagnostics. That makes the same hook definitions usable locally and in automated pipelines without introducing a separate configuration path.
Its standout depth is workflow coordination: independent check and fix steps run concurrently, while read and write locks coordinate file access. Pre-commit workflows can automatically fix files, stage changes and use Git-based stashing. Grouped, directory-aware configurations address monorepos, and the broad hook-stage coverage reaches beyond basic pre-commit tooling. Teams wanting comprehensive, CI-ready lifecycle management should consider hk. Those seeking a managed service, vendor-operated deployment or support beyond documentation and community channels should look elsewhere.
