Caret range
Version: 1.4.0 Range: ^1.2.3
Satisfies — ^1.2.3 allows any 1.x.y at or above 1.2.3, but not 2.0.0.
Semver Comparator
Compare two semantic versions or check whether a version satisfies a range.
1.2.3 is less than 1.3.0
- Major
- 1 / 1
- Minor
- 2 / 3
- Patch
- 3 / 0
- Prerelease

About this tool
Semantic Versioning (semver) gives a version number — major.minor.patch, e.g. 2.4.1 — a precise meaning: a major bump can break compatibility, a minor bump adds functionality safely, and a patch fixes bugs without changing the API. Package managers like npm compare and constrain versions using this exact rule set.
This tool implements the comparison and the common range operators (>=, <=, ^, ~) so you can check, without installing anything, whether a version satisfies a dependency constraint.
How to use it
- In Compare mode, enter two versions to see which one is newer and how their major/minor/patch/prerelease parts differ.
- In Satisfies Range mode, enter a version and a range such as ^1.2.3 or >=1.2.0 <2.0.0 — space-separated comparators are AND'd, and "||" separates alternative ranges, the same convention npm's own semver package uses.
Examples
Common problems
- My range uses "1.2.x" or a hyphen range like "1.2.3 - 2.3.4" and this tool rejects it.
- Those shorthand forms aren't implemented here — rewrite the range using explicit comparators, e.g. ">=1.2.3 <=2.3.4" instead of a hyphen range.
