What it does
The Semver Checker works with Semantic Versioning 2.0.0 strings. Compare two versions to see which is greater (with correct prerelease precedence - 1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0), test whether a version satisfies an npm-style range (^, ~, comparators, hyphen ranges, ||), and bump major / minor / patch / prerelease in one click. Everything runs 100% client-side - no version string ever leaves your browser.
How to use it
- Compare - enter two versions in Version A and Version B. The arrow between them and the verdict line tell you which is greater (or that they are equal).
- Range check - enter a version and a range expression (e.g.
^1.2.0,~1.0.0,>=1.2.3 <2.0.0,1.0.0 || 2.0.0). A green satisfies or red no match badge shows the result. - Bump - enter a version, then click Major, Minor, Patch, or Prerelease to compute the next version and copy it.
- Copy share link to send the exact inputs to someone else.
Examples
Compare (prerelease ordering)
1.0.0 vs 1.0.0-beta → 1.0.0 is greater than 1.0.0-beta (a release always outranks its prereleases).1.2.3 vs 1.2.10 → 1.2.3 is less than 1.2.10 (numeric, not lexicographic - 10 > 3).Range check
1.5.0 against ^1.2.0 → satisfies (compatible-with stays inside major 1).1.2.2 against ^1.2.3 → no match (^1.2.3 requires >=1.2.3).1.5.0 against >=1.2.0 <2.0.0 || 3.0.0 → satisfies (the first AND clause holds).Bump
1.2.3 → Major 2.0.0 · Minor 1.3.0 · Patch 1.2.4 · Prerelease 1.2.4-01.2.3-beta.2 → Prerelease 1.2.3-beta.3 (increments the trailing numeric identifier).Good to know
- Prerelease precedence follows the semver.org spec: numeric identifiers are compared by value and rank lower than alphanumeric ones; a version with no prerelease is always higher than one with. Build metadata (
+…) is ignored for ordering. - Ranges support
^(caret),~(tilde),>= > <= < =,*/xwildcards, partials (1,1.2), hyphen ranges (1.2.3 - 2.3.4), space-separated AND, and||OR - the same grammar npm uses inpackage.json. - Invalid input is reported inline rather than throwing: a malformed version or range shows a red warning instead of a verdict.
- Shareable: all three sections’ inputs are encoded in the URL.
- Private: all parsing happens locally - safe for any version string.
