Promptowl
Cloud memory forgets why it changed something. Here's how to build a second brain with Claude and a governed context layer — and follow along step by step.
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 9 July 2026; the live site may have changed since.
Promptowl has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: missing several security headers and incomplete email security.
Launched on Hacker News on July 9, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered in 2024. Our crawler found 23 technologies on this site, covering analytics, email security, security, and seo. The stack includes Next.js, React, and Tailwind CSS.
It's also running the same core stack as 9,830 other launches.
