Bump check
the required level (major/minor/patch/none) comes from every commit since the last v* tag (or --base <ref>) that touches the package directory, so it works per-package in monorepos. Merge commits and release commits are ignored.

semver-gauge
A CI gate that checks your version bump matches what changed, and that the CHANGELOG has a real entry for it.
CI gate that checks your version bump matches the changes since the last release (Conventional Commits: breaking/feat/fix) and that CHANGELOG.md has a real entry for the new version. Text/JSON/SARIF/Markdown, allowlist with expiry, GitHub Action. Zero deps.

$ npx semver-gaugesemver-gauge — version 1.3.01.2.0 → 1.3.0 (2 commit(s) since v1.2.0; changes need: major, expected 2.0.0) HIGH package.json 1.2.0 → 1.3.0 is a minor bump but the changes need major (e.g. "feat!: remove the legacy export") [insufficient-bump] ↳ fix: Bump to 2.0.0, or if nothing is actually breaking, fix the commit type. 1 high✖ Failing (fail-on: high).
Why it exists
semver-gauge looks at the commits since your last release tag, works out the bump they need from Conventional Commits (feat → minor, fix/perf → patch, “!” or a “BREAKING CHANGE:” footer → major) and compares that with the version in package.json. A breaking change shipped as a minor, a version that went backwards, a skipped version or a tag that already exists is reported with a severity and a concrete fix ("Bump to 2.0.0"). It also checks that CHANGELOG.md has a non-empty, correctly dated entry for the version, at the top.
CLI, library and GitHub Action. Node.js 18+, zero runtime dependencies. By Louis Wright.
Features
SemVer rules done properly
pre-release precedence (1.0.0-rc.1 → 1.0.0-rc.2 → 1.0.0), 0.x semantics (breaking → minor, feature → patch) and the 0.x → 1.0.0 graduation.
CHANGELOG check
Keep a Changelog (## [1.2.0] - 2026-01-01), ## 1.2.0 (2026-01-01) and # v1.2.0 headings; empty entries, out-of-order entries, future or impossible dates, and a forgotten [Unreleased] section.
No git needed
--commits <file> and --base-version let you feed it commit messages from anywhere.
Output
text, JSON, SARIF 2.1.0 and Markdown; --fail-on; exit codes 0/1/2; allowlist entries with expiry dates.
Usage
# check package.json against the latest v* tag and CHANGELOG.md
npx semver-gauge# compare with another ref
npx semver-gauge --base origin/main# release PRs: releasable commits must come with a bump
npx semver-gauge --require-bump# just check CHANGELOG.md has an entry for the current version
npx semver-gauge --changelog-onlyCI / GitHub Action
