Diffwatch monitors competitor changelogs and release note pages — and emails you an AI-written summary the moment they ship a new version, so you never fall behind on what changed in their product.
Drop in any public /changelog, /release-notes, or /whats-new page. Works on Stripe, Linear, Vercel, your competitors — any URL is fair game.
Use the CSS selector mode to watch only the release entries, not nav, footer, or marketing copy. Cookie-banner churn won't trigger false alarms.
When a competitor publishes a release, Diffwatch fires an email with an AI-written summary of what changed — bug fixes, new features, removals — no manual diff reading required.
Direct competitors' /changelog or /release-notes pages are the highest-signal sources. Most modern SaaS companies publish there within minutes of shipping; watching 3–5 changelogs weekly gives you a complete picture of who's moving and how fast.
Pro plan checks every 5 minutes — you'll typically know within minutes of a version going live. Free plan checks every 60 minutes, which is still faster than most RSS or email digests.
Yes. GitHub releases (/releases) and GitLab release pages render as public HTML — paste the URL and Diffwatch tracks new release entries exactly like any other changelog.
Diffwatch fetches rendered HTML, so client-side content renders correctly in most cases. If a page renders fully client-side, narrow with a CSS selector targeting the entry list. Test the selector with the inline testing tool before saving.
