Simten

A TypeScript HDL where npm is your testbench — from logic gates to a RISC-V CPU. Test circuits against real firmware, then synthesize to Verilog.

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 June 2026; the live site may have changed since.

Simten looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and incomplete email security.

Launched on Hacker News on June 9, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 8 weeks before launch. We've detected 9 technologies on this site, covering build tooling, CDN, CSS frameworks, and DNS providers. The stack includes Tailwind CSS, Vite, and Cloudflare.

It's running the same core stack as 3,033 other launches.
