Changelog and Release Notes Tool

Publish product updates to a hosted page, an in-app widget, and email subscribers.

TL;DR

A changelog tool lets software teams publish release notes on a branded page, an embeddable widget, and an email digest. Small SaaS companies pay a monthly fee to keep customers informed without building it themselves. A fast editor, clean design, and simple pricing are the main differentiators. Expect to spend about $100–$1.5k to start, earn your first dollar in 4–8 weeks, and reach roughly $500–$7k/mo after a year of steady work.

§ 01

Why a Changelog and Release Notes Tool works now

Shipping faster with AI coding tools means more frequent releases to communicate. Customers expect visible progress. Existing tools are either heavyweight or basic, leaving room for a polished mid-point.

§ 02

Who pays and how you make money

Early-stage SaaS products and open-source teams that ship often and want customers to see updates. Product managers at small companies are the buyers.

  • $Monthly subscription
  • $Custom domain add-on
  • $Subscriber-count tiers

§ 03

How to start a Changelog and Release Notes Tool

  1. 1

    Design the core flow

    Build a markdown-based editor, a public hosted page, and an RSS feed. Focus on speed of writing and a clean reading experience.

  2. 2

    Build the widget

    Create a small JavaScript snippet that shows a what’s-new badge and popover inside the customer’s app.

  3. 3

    Add email digests

    Let readers subscribe and send a digest on publish using Resend or Postmark.

  4. 4

    Integrate with dev tools

    Pull merged pull requests from GitHub or issues from Linear to draft entries, optionally summarized by a model.

  5. 5

    Support custom domains

    Offer a CNAME setup with automatic SSL for changelog.customer.com.

  6. 6

    Launch with open-source teams

    Offer free hosting for open-source projects to build visibility, then charge commercial teams.

§ 04

Validate it in 7 days

Find 30 small SaaS products without a changelog and email founders a mockup of a page for their product. Ask whether they would pay $15 a month. Even three replies requesting setup is a useful signal.
