Calculate Major, Minor, and Patch version increments and validate package dependency ranges.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Enter your starting version string (e.g. 2.4.1 or 1.0.0-beta.1).
View the automatically generated Major, Minor, and Patch target versions.
Enter a dependency range (e.g. ^2.4.0) to test if your version satisfies the package requirement.
The caret (^) allows minor and patch updates (e.g., ^1.2.3 allows >=1.2.3 <2.0.0), while the tilde (~) restricts updates to patch releases only (e.g., ~1.2.3 allows >=1.2.3 <1.3.0).
Increment Major when you introduce breaking API changes that are incompatible with previous consumer code.
