Three small browser primitives

Open-source software by Sarwagya Singh — problems I solved for myself. Apparently a few other people had them too.

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 6 July 2026; the live site may have changed since.

Three small browser primitives covers some of the launch checklist, with a thorough launch checklist, fast page loads, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on July 5, 2026. The site is hosted on Vercel, with a domain registered 1 week before launch. Our crawler found 4 technologies on this site, covering frameworks, hosting, meta-frameworks, and security. The stack includes Next.js, React, and HSTS.

It's also on one of the most common stacks we track, shared by 1,973 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
