AsyncFutures
Show HN: AsyncFutures – A Ruby gem for asynchronous/concurrent code execution
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 12 July 2026; the live site may have changed since.
AsyncFutures is partway there, with well-configured email security. Worth fixing first: no Permissions-Policy, incomplete legal pages, and no sitemap.
Launched on Hacker News on July 12, 2026. The site is served through Fastly. The crawl picked up 15 technologies on this site, covering transactional email, social embeds, analytics, and CDN. The stack includes Stimulus, Tailwind CSS, and Bluesky.
For context, it's a rare Stimulus sighting, just 28 in our data and tighter on security headers than most Hacker News launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
