Question 1

What is a Semver checker?

Accepted Answer

A Semver checker is a tool that validates whether a version number follows the Semantic Versioning 2.0 specification (MAJOR.MINOR.PATCH format). It checks for proper structure, valid characters, leading zero rules, and optionally parses prerelease tags and build metadata. This free online checker gives instant results in your browser.

Question 2

What version formats does this checker support?

Accepted Answer

This Semver checker supports the full Semver 2.0 specification: standard versions like 1.0.0, prerelease versions like 2.1.3-beta.1 or 1.0.0-alpha+001, and build metadata like 1.2.3+build.456. It also handles leading 'v' prefix (v1.2.3) automatically. It rejects invalid formats such as leading zeros (01.2.3) and extra segments (1.2.3.4).

Question 3

How is this different from a Semver validator?

Accepted Answer

This checker focuses on quick single-version validation with instant visual feedback. If you need batch validation, version comparison, or range matching (^, ~), try our full-featured Semver Validator which supports all those advanced operations.
