Osscar
A quarterly ranking of the fastest-growing open-source organizations, by Supabase and >commit.
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 28 April 2026; the live site may have changed since.
Osscar covers some of the launch checklist, with a complete set of security headers, a thorough launch checklist, and fast page loads. Visible gaps: incomplete legal pages, no robots.txt or sitemap, and tracking cookies set before any opt-in.
Launched on Hacker News on April 28, 2026. The site is hosted on Vercel, with a domain registered 4 weeks before launch. Our crawler found 11 technologies on this site, covering transactional email, analytics, captcha, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
It's also on one of the most common stacks we track, shared by 10,662 launches and more locked down than the typical Hacker News launch.
