Semver Calculator

Parse, compare, validate, and bump semantic versions. Check range satisfaction (^, ~, >=, <, wildcards, OR/AND). Sort version lists. Supports pre-release and build metadata per the SemVer 2.0.0 spec. Runs entirely in your browser — your data never leaves your machine.

All interactive tools run entirely in your browser. Your data never leaves your device.

How It Works

Enter a semantic version (e.g. 1.2.3-beta.1+build.42) and explore it across five tabs: Parse breaks it into major/minor/patch/pre-release/build components; Compare shows which of two versions is greater; Range checks if a version satisfies a range expression; Bump shows all possible version increments; Sort orders a list of versions.

Features

  • 5 tabs: parse, compare, range check, bump, sort
  • Full SemVer 2.0.0 support: major.minor.patch, pre-release identifiers, build metadata
  • Range operators: ^ (caret), ~ (tilde), >=, <=, >, <, =, x/* wildcards, hyphen ranges, || OR
  • Version bumping: major, minor, patch, premajor, preminor, prepatch, prerelease
  • Version sorting: ascending/descending, handles pre-release ordering
  • Version coercion: partial versions (e.g. 1.2) coerced to valid semver
  • 5 examples: basic, pre-release, tilde, wildcard, OR range
  • Copy to clipboard: one-click copy for bump results and sorted lists
  • Private: runs entirely in the browser — no data transmitted

Use Cases

  • Checking if a package version satisfies a dependency range
  • Planning version bumps for releases
  • Sorting changelog entries by version
  • Validating version strings in CI/CD pipelines
  • Understanding semver pre-release precedence
