Contextual
A local-first AI context engine with semantic search, temporal recall, and on-device indexing.
Estimated origin: India
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 27 August 2026; the live site may have changed since.
Contextual ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. What needs work: incomplete email security.
Launched on Hacker News on August 27, 2026. The site is hosted on OpenNext and served through Cloudflare, with a domain registered 6 weeks before launch. Our crawler found 18 technologies on this site, covering security, ui library, auth, and captcha. The stack includes Clerk, Next.js, and React.
It's also running the same core stack as 978 other launches and tighter on security headers than most Hacker News launches.
