Dummy Changelog Entry Generator

Used by developers, writers, and creators worldwide.

A dummy changelog entry generator gives developers realistic CHANGELOG.md files in seconds, without writing placeholder text by hand. Built on the Keep a Changelog convention, it produces multi-version entries organized into Added, Fixed, Changed, and Deprecated sections — exactly what changelog parsers, documentation pipelines, and release tooling expect, with proper semantic versioning throughout. Project type shapes the vocabulary. Choose CLI tool and you get flags, exit codes, and shell behavior. Pick API library and entries reference endpoints, deprecations, and version pinning. Mobile app logs mention OS compatibility and permissions. Select the style that fits your context and the output reads like real project history.

How to use

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

Detailed instructions

  1. Set the Number of Versions slider to how many release blocks you need (3 is enough for most demos).
  2. Choose the Project Type that matches your context: web app, CLI tool, API library, or mobile app.
  3. Click Generate to produce a full CHANGELOG in Keep a Changelog format with dated version headings.
  4. Copy the output and paste it into your fixture file, documentation site, or README preview to verify rendering.

Use Cases

  • •Stress-testing a changelog parser script with multi-version edge cases in Jest fixtures
  • •Populating a documentation site demo before a product's first real release ships
  • •Building CI pipeline fixtures that require realistic historical version metadata
  • •Teaching open-source contribution practices with real-looking Added, Fixed, and Deprecated entries
  • •Prototyping a changelog-driven release timeline UI component in Storybook before real data exists

Tips

  • →Generate the same version count twice with different project types, then merge sections to create a realistic monorepo-style changelog.
  • →For parser testing, generate 5 versions and manually remove one section heading — your parser should handle sparse version blocks without crashing.
  • →CLI tool output tends to have the most varied Fixed entries; use that style when you need diverse bug-fix copy for documentation templates.
  • →Paste the output into a Markdown previewer like GitHub's or readme.so before embedding it in docs — column alignment and heading levels render differently across tools.
  • →If you need an [Unreleased] block, copy the topmost version block from the output, remove the date, and change the version number to [Unreleased] — the subsection structure is identical.
  • →Mobile app style generates OS-version compatibility notes and permission change entries, making it the best choice for testing changelogs that include non-code release metadata.

FAQ

how do I test a changelog parser with fake data

Generate 3 or more versions, copy the raw output, and drop it into your parser as a fixture file. Look for edge cases like versions with only one section or multiple subsections in a single block — these surface off-by-one errors fast. Running several batches gives you varied entry counts per section, which is usually where parsing logic breaks.

is Keep a Changelog format the same as conventional commits

They are related but different. Keep a Changelog is a formatting convention for CHANGELOG.md files — it defines sections like Added, Fixed, and Deprecated under dated version headings. Conventional Commits is a commit message spec that tools like git-cliff or release-please use to auto-generate those files. This generator produces Keep a Changelog output directly, without needing any commit history.

which project type should I pick for a REST API backend

Choose API library. That style generates entries referencing endpoints, response schemas, rate limits, and authentication headers — vocabulary that fits a REST or GraphQL backend. The web app style focuses on UI components and user-facing flows, which look out of place in API documentation.
