No description of API-Diff.io yet.

Every update you don't communicate is a feature your users will never find. Your team ships improvements every week — bug fixes, new features, performance gains. But if your users don't hear about them, those updates might as well not exist. Features go undiscovered. Support tickets pile up for...

  • AI Release Notes from GitHub
    Connect your repo and ReleasePad reads your commits and PR descriptions, then turns them into user-friendly entries. Nothing publishes without your approval — you review, then ship. Never write release notes again.
  • In-App Changelog Widget
    A 4.3kb embeddable widget that shows updates right inside your product — lighter than most logo files. One line of code, 30 seconds to install, nothing to maintain.
  • Public Changelog Page
    A hosted, SEO-friendly page your users can bookmark, on your own subdomain. Built to be crawled by Google, ChatGPT, Claude, and Perplexity, with a Markdown endpoint for AI systems — plus analytics showing which updates users actually engaged with.

Questions & Answers

As answered by people managing API-Diff.io and ReleasePad.

Which are the primary technologies used for building your product?

ReleasePad's answer:

Elixir + Phoenix + Redis + TailwindCSS + Vanilla JavaScript.

Who are some of the biggest customers of your product?

ReleasePad's answer:

-Orbitly -Stacklane -Nexaform -Claritask

What makes your product unique?

ReleasePad's answer:

Most changelog tools assume you'll write the release notes. ReleasePad assumes you won't. It connects to your GitHub repo, drafts release notes from merged PRs and commits using AI, and waits for one click of approval before publishing. From there it distributes to three places at once: a 4.3kb in-app widget, a public hosted SEO page, and a machine-readable Markdown URL that ChatGPT, Claude, and any other model can read. That third channel is the part nobody else ships, when a user asks an AI assistant "what changed in this API?", ReleasePad makes sure the assistant has the real answer instead of guessing.

Why should a person choose your product over its competitors?

ReleasePad's answer:

Pricing and effort. Beamer starts at $49/mo and scales with monthly active users; Canny's Pro plan starts at $79/mo and scales with tracked users. ReleasePad is $35/mo flat per product, same price for a team of 1 or 200, no per seat fees, no usage cliff as you grow. And the DIY route (Notion, a blog, a Confluence page) is only free until you count the hours: you still write every entry by hand, still maintain the page, and still get no in-app surface or analytics. ReleasePad takes 30 seconds and one line of code to install, drafts the writing for you, and tells you which updates people actually opened.

How would you describe the primary audience of your product?

ReleasePad's answer:

SaaS teams that ship faster than they communicate, indie hackers, solo founders, and small-to-mid product and engineering teams who merge PRs weekly but have no dedicated marketing or docs person. Typical buyer is a founder, head of product, or engineering lead at a product-led company where releases are constant and invisible. 153+ teams use it today, with 15,793+ release notes published..

What's the story behind your product?

ReleasePad's answer:

I've worked in technology companies all my life. I've kept watching teams merge twenty PRs a month while their end users, and their prospects, assumed the product had stalled. The changelog was always the last thing anyone wrote and the first thing that fell off. ReleasePad's premise is that if it isn't announced, it didn't happen: buyers check your pulse before they pay, and now AI assistants answer questions about your product whether or not you've given them anything accurate to read. The June 2026 launch of machine-readable Markdown output made that second audience explicit, your changelog now has human readers and agent readers, and both should get the same source of truth.
