pre-commit-uv
Run pre-commit with uv
Decision gist · record as of 2026-08-14
Yes, if you use pre-commit and want faster initial hook installation without configuration changes. The low install friction, active maintenance, permissive license, and demonstrated performance gain (roughly 30% faster in the benchmark) make it a straightforward win. Install via pipx inject or uv tool install, and it works transparently. No known vulnerabilities.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires pre-commit to already be installed; works with Python 3.10 or later.
- Low friction install as a pure Python wheel.
- Actively maintained with a recent release; repository shows steady activity and no archived status.

pipx inject pre-commit pre-commit-uv
Then use pre-commit normally; pre-commit-uv will automatically patch pre-commit to use uv for environment creation and package installation.- Whether the 1.30x speedup shown in the benchmark holds across different project configurations and cache states.
- Compatibility with all pre-commit hook types and custom hook configurations.
- Whether the DISABLE_PRE_COMMIT_UV_PATCH and FORCE_PRE_COMMIT_UV_PATCH environment variables cover all edge cases.
What it is and what it does
pre-commit-uv is a plugin that replaces pre-commit's default virtual environment and package installation mechanism with uv, a faster Rust-based Python package installer. It works by patching pre-commit at runtime to use uv instead of the standard tools, transparently speeding up the initial hook installation and environment setup without requiring changes to your pre-commit configuration.
The package is installed as an injection into an existing pre-commit installation (via pipx inject) or alongside it (via uv tool install). Once active, it automatically intercepts pre-commit's environment creation calls and delegates them to uv, which typically reduces hook installation time by roughly 30% according to the project's own benchmarks. It includes escape hatches via environment variables to disable the patching if needed, and only applies the patch when pre-commit is actually invoked to avoid startup overhead.
Use it for
- Speed up initial pre-commit hook installation in CI/CD pipelines where cache is unavailable or ephemeral.
- Reduce local development setup time when running pre-commit install-hooks for the first time on a new machine.
- Replace pre-commit's default package installer in projects where uv is already the standard tool.
- Maintain faster hook environments in monorepos or projects with many dependencies.
- Disable selectively on specific machines or environments using the DISABLE_PRE_COMMIT_UV_PATCH variable.
