Semantic Versioning (SemVer)

What Is Semantic Versioning?

Semantic Versioning (SemVer) is a versioning scheme that uses a three-part number format: MAJOR.MINOR.PATCH. The MAJOR version increments when you make incompatible API changes, the MINOR version increments when you add backward-compatible functionality, and the PATCH version increments when you make backward-compatible bug fixes. Pre-release versions can be denoted with a hyphen and label (e.g., 1.0.0-alpha.1), and build metadata with a plus sign (e.g., 1.0.0+build.123). This calculator helps developers manage version bumps according to SemVer rules, validate existing version strings, and compare two versions to determine their relationship. It is essential for package management, release planning, and maintaining dependency compatibility.

How to Use This Tool

1. Enter the current version — Type or paste the current semantic version (e.g., 1.0.0) in the input field.
2. Select bump type — Choose from Major, Minor, Patch, or pre-release variants to determine the next version.
3. Choose pre-release label — For pre-release bumps, select a label (alpha, beta, rc, dev, next).
4. Click Calculate — The tool computes the next version following SemVer rules and displays the result.
5. Compare versions — Use the version comparison section to compare two versions and see which is greater.
