Screenshot of Steffi - Autonomous AI Agents in Rust

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

Steffi - Autonomous AI Agents in Rust ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy and no email security records.

Launched on Product Hunt on August 11, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered in 2022. We've detected 12 technologies on this site, covering javascript library, CDN, cloud, and CSS frameworks. The stack includes Tailwind CSS, Amazon Web Services, and AWS CloudFront.

It's running the same core stack as 276 other launches and tighter on security headers than most Product Hunt launches.
