ChangeLoggy: share product updates with a "What's New" widget
ChangeLoggy is the easiest way to add a "What's New" changelog widget to your web
app. Write updates in a simple editor and publish, and a lightweight floating widget
shows your latest release notes to your users. No Git integrations, no build step,
just one line of code. It is built and operated by Media Lantern, Inc.
How it works
Add the widget with one line before your closing body tag:
<script src="https://changeloggy.com/widget.js" data-project="YOUR_PROJECT_ID"></script>.
Your visitors need no account. You write and publish updates from the dashboard, or
let an AI coding agent publish them for you over MCP.
Features
- Floating "What's New" widget with an unread indicator.
- Markdown editor with unlimited updates on every plan.
- A hosted archive page for each project.
- Per-project RSS feed (Pro).
- White-labeling to remove the "Powered by ChangeLoggy" badge (Pro).
- An MCP server so AI coding agents can publish release notes automatically.
- No cookies and no end-user tracking on the sites where you embed the widget.
Pricing
Free: $0 forever, with unlimited updates, the editor, and the widget. Pro: $19.99 per
year (about $2 per month), which adds white-labeling and RSS feeds.
