FAQ
How to validate semver version strings online?
Paste a version like 2.0.0-beta.1 to check SemVer 2.0.0 syntax before tagging npm packages or GitHub releases.
How to compare semantic version numbers?
Enter two SemVer strings to see whether the first is older, equal, or newer—pre-release segments sort before the release.
What is the next patch version after 1.2.3?
Use bump buttons—patch on 1.2.3 yields 1.2.4. Major and minor bumps update left segments and reset lower ones.
What do pre-release tags mean in SemVer?
Suffixes like -alpha.1 or -rc.2 mark builds before stable release; they sort lower than the same version without a pre-release label.
Does this semver validator work for npm packages?
Yes—it follows npm-style SemVer rules for compare, validate, and bump operations entirely in your browser.
