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 for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 19 May 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.

InstantSales is largely in shape, with complete legal pages, well-configured email security, and clean crawl signals. Main gaps: missing several security headers.

Launched on Product Hunt on May 19, 2026. The site is hosted on Google Cloud. The crawl picked up 14 technologies on this site, covering business email, AI builders, backend framework, and CSS frameworks. The stack includes Tailwind CSS, Express, and Google Cloud.

For context, it's on one of the most common stacks we track, shared by 822 launches.
