Semantic Version Bumper
Preview semver bumps before tagging a release.
Preview a semver bump
Semantic versioning encodes intent — major for breaking changes, minor for features, patch for fixes — but it is easy to bump the wrong part before tagging. This tool previews what a major, minor, or patch bump does to a version so you tag deliberately.
Seeing the resulting version before you cut a release avoids the confusion of an accidental major bump or a skipped number. Enter the current version, pick the change type, and copy the correct next version for your tag or changelog.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
