Show HN: Clockclear – 12 ephemeral tools that auto-delete

Added June 29, 2026 · Last analysed June 29, 2026 · via Hacker News · 70% unique tagline

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 29 June 2026; the live site may have changed since.

Clockclear ships with the basics, with complete legal pages. Main gaps: missing several security headers, no sitemap, and incomplete email security.

Launched on Hacker News on June 29, 2026. The site is served through Cloudflare, with a domain registered in 2025. We've detected 3 technologies on this site, covering CDN, frameworks, and package cdn. The stack includes Vue.js, Cloudflare, and jsDelivr.

It's on one of the most common stacks we track, shared by 208 launches.
