upd

A fast dependency updater for Python and Node.js projects, written in Rust.

Features

• Multi-format support: Updates requirements.txt, pyproject.toml, and package.json
• Constraint-aware: Respects version constraints (e.g., >=2.0,<3 won't update to v3.x)
• Major version warnings: Highlights breaking changes with (MAJOR) indicator
• Format-preserving: Keeps your file formatting, comments, and structure intact
• Pre-release filtering: Excludes alpha, beta, and release candidate versions
• Gitignore-aware: Respects .gitignore patterns when discovering files
• Fast: Async HTTP requests with caching for quick subsequent runs
