Semantic Version Bumper & Comparator

About this tool

Bumps a semantic version number (major/minor/patch/prerelease) following the official semver rules, or compares two versions to see which one is actually newer — including correct handling of prerelease tags like 1.2.3-beta.1, which sort before their final release 1.2.3.

Frequently asked questions

What's the difference between major, minor, and patch?

Per semver convention: patch is for backwards-compatible bug fixes, minor is for backwards-compatible new features, and major is for breaking changes. Bumping major or minor resets the lower parts to zero (e.g. 1.5.2 → major bump → 2.0.0).

Why does 1.2.3-beta.1 compare as "older" than 1.2.3?

This is a deliberate rule in the semver spec — a version with a prerelease tag is considered a pre-release of that version, not a later one, so it always sorts before the plain (final) release with the same major.minor.patch.

What versions does this accept?

Standard MAJOR.MINOR.PATCH with an optional -prerelease and/or +build suffix (build metadata is accepted but ignored for comparison, per the spec) — an optional leading v is also accepted and stripped.
