About SemVer Comparator

SemVer Comparator is a browser-based utility for comparing versions such as 1.2.3, 2.0.0-rc.1, and 1.0.0+build.7 using Semantic Versioning precedence rules. This is useful for package maintenance, dependency checks, CI conditions, release workflows, API version review, and internal tooling where version order matters.

This tool parses the version structure, supports an optional leading v, and shows the comparison result immediately. It also displays the breakdown reason (major/minor/patch difference, prerelease status, etc.) so you can understand exactly why one version is higher or lower.

It is especially handy for validating release candidates versus final releases, checking upgrade logic, and avoiding subtle precedence mistakes before you encode the rules somewhere else. All processing runs entirely in your browser.

How to use SemVer Comparator

Enter the two semantic versions you want to compare (v prefix is optional).
Review the comparison symbol (>, <, =), normalized versions, and the breakdown explaining the difference.
Copy the result or use it for release validation, dependency checks, or documentation.
