Fake Semver Changelog Generator

Used by developers, writers, and creators worldwide.

A fake semver changelog generator produces realistic, structured version histories in seconds — no hand-writing release notes required. The output follows the Keep a Changelog convention: versioned headers with categorized entries for features, bug fixes, and breaking changes, all tied to your chosen project name. Set how many versions you need and the tool generates paste-ready Markdown you can drop straight into a repo. Developers use this to seed portfolio projects with plausible histories, scaffold a CHANGELOG.md before adopting semantic-release, or build fixtures for testing changelog parsers. It's also handy for educators who want a concrete, readable semver example rather than explaining version evolution from a blank file.

How to use

  1. Choose your options above
  2. Click Generate
  3. Copy your result

Detailed instructions

  1. Enter your project name in the Project Name field, matching the package name you use on npm, PyPI, or your repo.
  2. Set the Number of Versions to how many release entries you want, between 1 and 10.
  3. Click Generate to produce a Markdown-formatted changelog with versioned sections and categorized entries.
  4. Copy the output and paste it into a CHANGELOG.md file in your project root, or use it as a documentation template.
  5. Replace the synthetic entry descriptions with your actual release notes before committing to a public repository.

Use Cases

  • •Seeding a new npm package with a plausible CHANGELOG.md before its first public release
  • •Creating Markdown fixtures for unit-testing a changelog parser or git-cliff pipeline
  • •Populating a GitHub portfolio repo with a realistic multi-version project history
  • •Teaching junior developers semver conventions using a concrete, readable example
  • •Prototyping a CHANGELOG.md template before wiring up semantic-release or conventional-changelog

Tips

  • →Generate with four or more versions to get a realistic mix of MAJOR, MINOR, and PATCH releases — single-version output won't show the version progression.
  • →Use your exact npm or PyPI package name as the project name so the output is copy-paste ready without find-and-replace cleanup.
  • →Pair the generated changelog with a fake README generator to build a complete, convincing demo repository in minutes.
  • →When teaching semver, generate the same project twice with different version counts and compare how the version numbers evolve — it makes MAJOR vs MINOR decisions concrete.
  • →If you're scaffolding a real project, use the generated entries as category prompts — keep the Added/Fixed/Breaking headers and rewrite only the bullet descriptions.
  • →For CI pipeline testing, generate five or six different project names and feed the outputs as fixture files to cover varied changelog structures.

FAQ

how many versions should I generate for a realistic changelog

Four to six versions is a natural range — it gives you a mix of MAJOR, MINOR, and PATCH releases without feeling padded. If you're teaching changelog evolution or demoing a long-running library, generate eight or more to show a richer project arc.

can I use the generated changelog as a real CHANGELOG.md in my project

Use it as a structural scaffold, not finished copy. The formatting, version numbering, and section labels are production-ready, but the entry descriptions are synthetic — swap them out for your actual release notes before committing.

what's the difference between a minor and a patch release in semver

A MINOR release adds new backwards-compatible functionality — a new method, an optional config field, or a new endpoint. A PATCH release contains only backwards-compatible bug fixes. If one release includes both, bump MINOR.
