ChangeCrab badges display real update activity directly on your site, README, or docs - automatically and fairly.
Most users never open your changelog.
Even if your product ships regularly, the majority of visitors won’t click past your homepage, README, or documentation index. That means your latest updates stay hidden behind a link - while visitors quietly decide whether your project feels active or not.
ChangeCrab badges surface your changelog activity without requiring engagement, giving visitors instant reassurance that your project is alive and improving.

A changelog only proves activity once someone opens it.
For everyone else, it’s invisible. Visitors scanning a page or repository have no signal that updates are happening unless they actively dig for them. In practice, this means:
The issue isn’t unclear changelogs - it’s that most users never see them.
ChangeCrab badges turn your changelog into a passive signal of maintenance.
They display real update activity directly where users already are - homepages, READMEs, and documentation - so visitors can instantly see that a project is actively maintained without clicking anything.
Here’s a live activity badge embedded directly into Markdown:
This works anywhere Markdown is supported, including README files and documentation.
Automatic Updates
Embed once and forget about it. Badges update automatically as your changelog activity changes.
Fair Measurement
Activity is measured over time, not by raw post count. We track distinct weeks with updates, preventing short bursts from inflating results.
Multiple Badge Types
Choose the badge that fits your context:
Badges reflect real maintenance consistency, not vanity metrics.
