Rtrvr
RAG bots can only talk. API-tool agents ship a second maintenance org. Code sandboxes burn per-user server cost. Only DOM-native execution inherits the web's own truth model — live HTML, user session, existing IAM. A structural comparison.

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 18 April 2026; the live site may have changed since.
Rtrvr is largely in shape, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt, and incomplete email security.
Launched on Hacker News on April 17, 2026. The site is hosted on Vercel, with a domain registered in 2023. The crawl picked up 17 technologies on this site, covering advertising, transactional email, baas, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 10,672 launches.
