Semantic Version Generator
Used by developers, writers, and creators worldwide.
A semantic version generator gives you valid SemVer strings, including pre-release and build metadata, so you can fill in examples without second-guessing the format. Choose how many you want and it returns a shuffled set — clean releases like 2.3.1, pre-releases like 1.4.0-beta.2 and 3.0.0-rc.1, and versions with build metadata like 1.2.3+build.456. Developers use it for documentation, test fixtures, mock package manifests, and teaching how SemVer's MAJOR.MINOR.PATCH scheme works. Each string follows the official specification, including the rules for pre-release identifiers and build tags, so the examples are correct rather than merely plausible. Pick the versions that fit your scenario, drop them into a changelog, a package.json, or a test, and you have realistic version data instantly. It also doubles as a quick reference for what a valid pre-release or build-tagged version actually looks like.

FAQ
what do the version parts mean
MAJOR.MINOR.PATCH: bump MAJOR for breaking changes, MINOR for backward-compatible features, and PATCH for backward-compatible fixes. The optional -prerelease and +build tags add detail.
are pre-release versions lower than releases
Yes. By the spec, 1.0.0-alpha precedes 1.0.0. Pre-release identifiers sort before the matching release, which is why release candidates come before the final version.
does build metadata affect precedence
No. Build metadata after the plus sign is ignored when determining version precedence, so 1.0.0+build.1 and 1.0.0+build.2 are considered equal in ordering.
