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

Blanq — Bulk Chat Cleaner for ChatGPT covers some of the launch checklist, with a thorough launch checklist. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on April 21, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 3 technologies on this site, covering CDN, hosting, and security. The stack includes Fastly, GitHub Pages, and HSTS.

It's also running the same core stack as 1,757 other launches.
