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 problems you already fixed. Users churn thinking the product hasn't changed.
ReleasePad fixes that.
It connects to your GitHub repo and uses AI to read every change you ship — and turns them into clear, human-friendly release notes. No templates. No writing. No process to adopt. You ship code, ReleasePad tells the story.
Review, tweak if you want, and publish everywhere at once:
It works with messy repos, inconsistent commit messages, and the kind of chaotic history that real teams actually have. No strict formats required.
Whether you're a solo founder shipping with AI coding tools or a product team releasing multiple times a week, ReleasePad is the fastest path from "we shipped it" to "our users know about it.
Minutes, not hours. Automatic, not manual. Every update, every channel.

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.
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.
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..
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.

Using the zipcodestack API in your Node.js application is straightforward. You’ll first need to sign up for a free API key (it only takes a minute). Once you have your API key, you can call the REST endpoints using any HTTP client. Below is a simple example using Node’s built-in fetch (available in Node v18+), but you could use axios or any library of your choice:. - Source: dev.to / 11 months ago

I have seen this request pop up quite a few times. I did a quick search for free APIs of zipcode lookups. This one, named "zipcodestack" (I'm not in any way tied to, endorsing, or promoting them) seemed like a pretty good resource with up to 10,000 free lookups each month. So, I wrapped a quick script around it and made it a custom sheets function called GET_CITY:. Source: about 3 years ago
