Subproof — Track Subscriptions, Warranties & Agreements

This site was found by StackScope Discovery, our own first-party launch detection. The tech stack below comes from that discovery scan; the full analysis (screenshots, scores, page checks) is added when the site is picked up by a launch platform.

Track every subscription, warranty, and agreement in one place. Know exactly what you're paying for, when it renews, and what you're covered by. Proof of every payment. No surprises.

Own this Launch?

StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one to detect its tech stack. This page is what we saw on 21 August 2026; the live site may have changed since.

Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
