Retraceai
Record, replay, fork & share AI agent executions. See every LLM call, tool invocation, and error your agent makes — then debug and iterate in seconds.
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 25 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.
Retraceai ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing Permissions-Policy and Strict-Transport-Security and tracking cookies set before any opt-in.
Launched on Hacker News on June 25, 2026. The site is hosted on Render and served through Cloudflare. The crawl picked up 18 technologies on this site, covering javascript library, analytics, seo, and auth. The stack includes Google Sign-In, Next.js, and React.
For context, it's running the same core stack as 168 other launches and tighter on security headers than most Hacker News launches.

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 copy signals | +5 |
| AI onboarding signals | +5 |
| AI palette signals | +5 |
| 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.
