Rtrvr
DeepSeek Flash flips the economics of browser-agent harnesses: cheap cached text, code generation, DOM-aware execution, and no screenshot tool loop renting a frontier model as the runtime.
StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 26 June 2026; the live site may have changed since.
Rtrvr has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.
Launched on Hacker News on June 25, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2023. Our crawler found 21 technologies on this site, covering advertising, security, analytics, and baas. The stack includes Next.js, React, and Tailwind CSS.
Notably, it's running the same core stack as 8,554 other launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|

| 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.
