Own this Launch?

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 22 April 2026; the live site may have changed since.

openchalkboard.app is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 22, 2026. The site is hosted on Neocities, with a domain registered 1 day before launch. We've detected 3 technologies on this site, covering DNS providers, hosting, and security. The stack includes HSTS, Neocities, and Porkbun DNS.

It's a rare Neocities sighting, just 7 in our data.
