bumpver
Bump version numbers in project files.
Decision gist · record as of 2026-08-14
Yes. BumpVer is actively maintained, has no known vulnerabilities, low install friction, and a permissive MIT license. It solves a real problem—automating version updates across multiple files—with flexible pattern support for SemVer, CalVer, and custom schemes. The tool is well-suited for both Python and non-Python projects. Install it if you manage versions across multiple files and want to automate the bumping process.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
BumpVer is a version-bumping CLI tool that automates finding and updating version strings in your project files. You define a version pattern (supporting SemVer like MAJOR.MINOR.PATCH, CalVer like YYYY.MM, or custom schemes) and file patterns to search, then BumpVer handles the search-and-replace across your codebase. It normalizes versions according to PEP440 and can optionally integrate with Git or Mercurial for VCS-aware bumping.
The tool works with plaintext files, so it's not limited to Python projects—you can use it with any language or project type. It supports dry-run mode to preview changes before applying them, and provides a test command to validate your version patterns before committing them to configuration.
Use it for
- Automate version bumping in CI/CD pipelines for multi-file projects using SemVer or CalVer schemes.
- Test and validate version patterns before configuring them in your project's version configuration.
- Update version strings across setup.py, __init__.py, and other project files in a single command.
- Manage CalVer versioning with automatic date-based increments and optional patch numbers for multiple releases per period.
- Preview version changes with dry-run mode before committing them to version control.
