BlazeDiff Agent

Open-source visual regression for JS. Deterministic Rust + JS diff cores (3 to 8x faster than pixelmatch and odiff on 4K), SSIM/GMSD metrics, and an agent that hands ambiguous diffs to Claude Code, Cursor, or Codex. No SaaS, no API key.

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 3 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.

BlazeDiff Agent still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on June 3, 2026. The site is hosted on Vercel, with a domain registered 8 months before launch. The crawl picked up 7 technologies on this site, covering analytics, DNS providers, email forwarding, and frameworks. The stack includes Next.js, React, and HSTS.
