upd

A fast dependency updater for Python, Node.js, Rust, Go, Ruby, .NET, Terraform, GitHub Actions, pre-commit, and Mise projects, written in Rust.

Quick Start

# Preview changes without modifying files (default)
uvx upd

# Apply updates
uvx upd --apply

# Or with pipx
pipx run upd --apply

Features

• Multi-ecosystem: Python, Node.js, Rust, Go, Ruby, .NET, Terraform, GitHub Actions, pre-commit, Mise/asdf
• Dry-run by default: nothing is written without --apply
• Fast: parallel registry requests, with a 24-hour version cache
• Constraint-aware: respects >=2.0,<3 (Python), ~> 7.1 (Ruby), and ^2.0.0 / ~2.0.0 (npm, Cargo)
• Format-preserving: keeps formatting, comments, and structure
• Update filters: --only-bump, --max-bump, --package, --lang, or approve one by one with -i
• Major warnings: breaking changes are flagged with (MAJOR)
• Pre-release aware: updates pre-releases to newer pre-releases
• Cooldown: hold back releases younger than N days, against supply-chain attacks
• Security auditing: OSV vulnerability scanning with auto-fix and SARIF output
• Check mode: exit 1 if updates are available (for CI and pre-commit)
• Gitignore-aware: honors .gitignore and prunes hidden directories, without missing the dotfiles it updates
• Private registries: authentication for PyPI, npm, Cargo, Go, and GitHub
• Config file: ignore or pin packages via .updrc.toml

Installation

From crates.io

cargo install upd

# or with cargo-binstall (faster, pre-built binary)
cargo binstall upd

From PyPI

pip install upd
# or with uv
uv pip install upd

If you installed an earlier release under the old distribution name, migrate once with pip uninstall upd-cli && pip install upd. The upd-cli command remains available as a compatibility alias.

From source

git clone https://github.com/rvben/upd
cd upd
cargo install --path .

Usage

# Preview changes without modifying files (default when no --apply)
upd

# Apply updates to files
upd --apply

# Limit to specific files or directories
upd --apply requirements.txt pyproject.toml

# Approve updates one by one
upd -i

# Only the packages you name
upd --package requests,flask

# Cap the bump level (allow patch + minor, skip major). Updates above the
# ceiling are reported as held back, never as up to date, and do not
# change the exit code.
upd --max-bump minor

# Restrict to exactly one level (repeatable, comma-separated)
upd --only-bump major

# One ecosystem at a time: python, node, rust, go, ruby, dot-net,
# terraform, actions, pre-commit, mise, annotated
upd --lang python

# Exit 1 if anything is outdated (for CI and pre-commit)
upd --check

# Regenerate lockfiles after writing
upd --apply --lock

# Print the effective configuration and exit
upd --show-config

upd --help lists every flag; Stability documents the ones that are contractual, and upd schema emits the whole interface as JSON.

Dry-run by default: upd without --apply only previews changes. Pass --apply to write updates. --check, --dry-run, and --interactive do not require --apply.

VCS-root scoping: When no path argument is given, upd scans from the nearest .git ancestor directory rather than the current working directory. This prevents accidental rewrites when CWD is a subdirectory inside a repository.

Commands

upd --version      # Print version
upd self-update    # Check for upd updates
upd clean-cache    # Clear the version cache
upd align          # Align versions across files (--check exits 1 on misalignment)
upd audit          # Scan for known vulnerabilities (exit 6 if found)
upd schema         # Machine-readable interface description

Example Output

.pre-commit-config.yaml:37: Would update pre-commit/pre-commit-hooks v4.6.0 → v6.0.0 (MAJOR)
.github/workflows/ci.yml:16: Would update actions/checkout v4 → v6 (MAJOR)
.github/workflows/ci.yml:18: Would update jdx/mise-action v2 → v4 (MAJOR)
.mise.toml:8: Would update rust 1.91.1 → 1.94.0
Cargo.toml:33: Would update clap 4.5.53 → 4.6.0
Cargo.toml:36: Would update tokio 1.48.0 → 1.50.0

Would update 6 package(s) (2 major, 3 minor, 1 patch) in 4 file(s), 8 up to date

Output includes clickable file:line: locations (recognized by VS Code, iTerm2, and modern terminals).

Version Constraints

upd respects version constraints in your dependency files:

For npm, comparator ranges such as ">=1.0.0 <2.0.0" are rewritten with a bump strategy: the lower bound moves to the highest version satisfying the constraint, preserving the upper bound. Hyphen ("1 - 2") and OR ("^1 || ^2") ranges are reported as warnings and left untouched rather than rewritten wrongly.

Version Precision

By default, upd preserves version precision from the original file:

# Original file has 2-component versions
flask>=2.0        →  flask>=3.1        (not 3.1.5)
django>=4         →  django>=6         (not 6.0.0)

# Original file has 3-component versions
requests>=2.0.0   →  requests>=2.32.5

# GitHub Actions major-only tags
actions/checkout@v3  →  actions/checkout@v4  (not @v4.2.0)

Use --full-precision to always output full semver versions:

upd --full-precision
flask>=2.0        →  flask>=3.1.5
django>=4         →  django>=6.0.0
requests>=2.0.0   →  requests>=2.32.5

Version Alignment

In monorepos or projects with multiple dependency files, the same package might have different versions:

# requirements.txt
requests==2.28.0

# requirements-dev.txt
requests==2.31.0

# services/api/requirements.txt
requests==2.25.0

upd align updates every occurrence to the highest version found:

upd align              # Align all packages to highest version
upd align --dry-run    # Preview changes
upd align --check      # Exit 1 if misalignments (for CI)
upd align --lang python # Align only Python packages

It only aligns within one ecosystem, skips packages with upper bound constraints (e.g. >=2.0,<3.0) to avoid breaking them, and ignores pre-release versions when finding the highest version.

Pre-commit Integration

Add upd to your .pre-commit-config.yaml:

repos:
  - repo: https://github.com/rvben/upd-pre-commit
    rev: v0.0.24
    hooks:
      - id: upd-check
        # Optional: only check specific ecosystems
        # args: ['--lang', 'python']

Available hooks:

Both hooks run on pre-push by default. Uses language: python which installs upd from PyPI automatically, so no manual installation is needed.
