SwimSight

Data-driven swim analytics for competitive swimmers and coaches.

Added June 28, 2026 · Last analysed June 28, 2026 · via · also on PeerPush

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 28 June 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.

SwimSight is partway there, with a complete set of security headers. Visible gaps: incomplete legal pages, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on June 28, 2026. The site is hosted on Upstash and served through Cloudflare. The crawl picked up 12 technologies on this site, covering hosting, security, analytics, and auth. The stack includes Clerk, Next.js, and React.

For context, it's one of 59 launches on this exact stack and more locked down than the typical Product Hunt launch.
