Screenshot of ShotWolf - Screenshot & render API

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 5 August 2026; the live site may have changed since.

ShotWolf - Screenshot & render API has the basics covered well, with a thorough launch checklist, fast page loads, and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and incomplete email security.

Launched on PeerPush on August 5, 2026. The site is served through Cloudflare, with a domain registered 11 weeks before launch. Our crawler found 9 technologies on this site, covering advertising, APIs, CDN, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.

It's also tighter on security headers than most PeerPush launches.
