Highflame
Anthropic open-sourced how it contains its coding agents. Here is the three-layer model, a real attack walked end to end, and the governance problem no sandbox solves: you run five agents and own none of them.

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 30 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.
Highflame is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers, no sitemap, and incomplete email security.
Launched on Hacker News on June 30, 2026. The site is hosted on Vercel, with a domain registered in 2001. The crawl picked up 8 technologies on this site, covering ai service, DNS providers, business email, and transactional email. The stack includes Cloudflare DNS, Google Search Console, and Google Tag Manager.
For context, it's on one of the most common stacks we track, shared by 4,270 launches.

Vibe Score Breakdown How?
| Signal | Points |

| Placeholder branding | +10 |
| AI palette 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.
