Conventional Commits give you two real things: an auto-generated changelog and automatic semver bumps. If you don’t have tooling consuming your commit messages, you’re paying a tax for nothing.

What you actually get

The format is type(scope): description — feat:, fix:, chore:, refactor:, with a BREAKING CHANGE: footer for major bumps. Tools like semantic-release or changesets parse that prefix to decide whether a merge is a patch, minor, or major version, and to build your CHANGELOG.md automatically.

That’s genuinely useful if you publish a package — an npm library, a CLI, anything with external consumers who read a changelog before upgrading. The commit history becomes the release notes for free.

What it costs

Every commit message now needs a type prefix, and someone has to enforce it, which usually means a commit-lint hook:

npm install -D @commitlint/cli @commitlint/config-conventional husky

Now every commit goes through a linter. Get the type wrong — fix when it should be feat, or forget the colon — and the commit is rejected. For a solo dev or a two-person team shipping an internal app with no changelog consumers, this is friction with no downstream who benefits.

The real question

Ask one thing: does anything read your commit history programmatically? If yes — you cut releases, you publish a package, you need semver bumps to be automatic — Conventional Commits pays for itself immediately. If no — you deploy on every merge to main, there’s no version number anyone checks — you’re just making commit messages more annoying to write for a benefit nobody collects.

The lighter alternative

Skip the type prefix. Keep one real rule: the first line says what changed and why it matters, not what files you touched.

Bad: update user.go Good: fix: null pointer when user has no avatar set

You get 80% of the value — a git log that’s actually readable, commits that explain themselves in git blame — without a linter rejecting your commits over a missing colon. Pair it with a PR template that has one required field, “what does this change and why,” and you get changelog-quality information without formatting rules.

If you later need automated releases, you can adopt Conventional Commits at that point — it’s not a decision you need to make on day one, and it’s cheap to bolt on later since it’s purely a commit-message convention, not a code change.

The team-size cutoff

The failure mode to avoid either way: a team that adopts Conventional Commits, no one wires up semantic-release or a changelog generator, and now everyone writes fix: and feat: prefixes for a linter with no downstream consumer. You paid the tax and got nothing. If you adopt the format, hook up the tool that reads it in the same PR — otherwise it’s decoration.
