Crankshaft

A free, private music engine that learns from what you actually do. Runs on your iPhone and iPad, collects nothing.

Added August 24, 2026 · Last analysed August 24, 2026 · via

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

Crankshaft ships with the basics, with well-configured email security and fast page loads. Visible gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on August 24, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. We've detected 6 technologies on this site, covering CDN, DNS providers, business email, and email forwarding. The stack includes Bluesky, Cloudflare, and Cloudflare DNS.
