This semver checker (semantic version checker or version range checker) verifies compatibility between versions and ranges. Use this free semver checker to check if a version satisfies a given semantic version range. Validate compatibility instantly.
This semver checker (or semantic version checker) verifies whether a version satisfies a given range.
Compatible ✅
Version is within the specified range
Version: 1.4.2 | Range: ^1.2.0
This semver checker allows you to verify if a version satisfies a version range (e.g., ^1.2.0, >=1.0.0). It helps ensure dependency compatibility in projects.
Use our full semantic versioning toolkit:
A semver checker tests whether a version string satisfies an npm-style range (^, ~, >=, <).
Free semver range checker — test whether a version string (e.g. 2.3.1) satisfies a range expression (^2.0.0, >=1.5.0 <3.0.0, ~2.3.x) following npm / SemVer 2.0 rules. Useful before upgrading package dependencies. No signup.
