MonoLisa v3

A font family designed for software developers. Font follows function.

Added June 22, 2026 · Last analysed June 22, 2026 · via · also on Hacker News

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 22 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.

MonoLisa v3 is largely in shape, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on June 22, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2019. The crawl picked up 13 technologies on this site, covering security, analytics, CDN, and DNS providers. The stack includes Next.js, React, and Cloudflare.

For context, it's on one of the most common stacks we track, shared by 3,472 launches.

AI writing 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.
