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 16 August 2026; the live site may have changed since.
Dudou covers some of the launch checklist, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.
Launched on Product Hunt on August 16, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 3 months before launch. Our crawler found 6 technologies on this site, covering CDN, cloud, DNS providers, and frameworks. The stack includes Svelte, SvelteKit, and Alibaba Cloud.
It's also on a stack we've seen on only 2 launches.
