Developer Tools

Added August 9, 2026 · Last analysed August 9, 2026 · via PeerPush

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 August 2026; the live site may have changed since.

Astound Dev Tools ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.

Launched on PeerPush on August 9, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. The crawl picked up 18 technologies on this site, covering analytics, javascript library, advertising, and captcha. The stack includes Google, Tailwind CSS, and CARTO.

For context, it's running the same core stack as 6,783 other launches and tighter on security headers than most PeerPush launches.
