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 29 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.
Checklane is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on June 29, 2026. The site is hosted on Timeweb, with a domain registered in 2025. We've detected 11 technologies on this site, covering analytics, CSS frameworks, developer tools, and business email. The stack includes Tailwind CSS, Microsoft Clarity, and nginx.
It's a rare Timeweb sighting, just 45 in our data.

Readiness Breakdown How?
Performance How?
Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI writing signals | +5 |
| AI iconography signals | +5 |
This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
