Changefeed

YES

Replaceable in one session with an AI coding agent.

A hosted changelog for a product: you write entries, it publishes a page, an RSS feed and an in-app widget so users see what shipped.

Promptfree, for everyone, and the only version there is

Build me a product changelog.

STACK
- Astro in static output, entries as Markdown files in the repository

ENTRIES
- One Markdown file per release with front matter: date, version, tags
- Tags are a fixed set — added, changed, fixed, removed — validated at build

THE PAGE
- Newest first, grouped by month, filterable by tag with no JavaScript beyond a details element
- An RSS feed and a JSON feed generated from the same files

THE WIDGET
- A script under 3KB that fetches the JSON feed and shows an unread count
- Unread is decided by comparing the newest entry date against one stored in localStorage
- Renders in a dialog element, keyboard accessible, closes on Escape

EMAIL
- A weekly digest of new entries to a list you already have; do not build a second list for this

Include the build, the widget and the feed generators.

What you lose

An in-app widget with an unread badge, which is what actually gets a changelog read
A hosted page with a custom domain and no deployment step
Email digests of new entries to people who asked for them

If you would rather not build

Keep a Changelog, plus a static site generator
A GitHub releases page, which is free
