Semantic Version Generator
Generates a random semantic-version-shaped string (MAJOR.MINOR.PATCH) — useful for changelog templates, mock release notes or documentation examples.
What this generator does
Produces a version string in semantic versioning format — major, minor and patch numbers separated by dots. Useful for populating a changelog mockup, a package fixture or a release-tooling test with something structurally valid.
How to use this tool
- Press generate for a version.
- Generate again for another one.
Worked examples
- Format
- 2.14.3
- Meaning
- Major.minor.patch, where a major bump signals a breaking change
Common use cases
- Changelog/release-note templates
- Documentation examples
- Teaching semantic versioning
How this generator works
A version is assembled in the major.minor.patch form, optionally with a pre-release tag and build metadata, following the ordering rules the specification defines. Those rules are less obvious than they look: 1.0.0-alpha sorts before 1.0.0, build metadata is ignored entirely when comparing, and numeric pre-release parts compare as numbers while alphabetic ones compare as text.
Limitations and good to know
- The numbers are random, so a sequence of generated versions will not increase in order the way a real release history does.
- Example versions for documentation and fixtures. They correspond to no package and are published nowhere.
- Build metadata after a plus sign is excluded from precedence, so two versions differing only there rank equally — which surprises most people the first time.
- A version below 1.0.0 signals, by convention, that the interface may change at any time. That is a convention, not a rule the format enforces.
