Tempo Checker

Show HN: Tempo Checker – Real-time disposable email detection API

Developer Tools

Added August 20, 2026 · Last analysed August 20, 2026 · via Hacker News · also on Product Hunt

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

Tempo Checker ships with the basics, with complete legal pages and fast page loads. Worth fixing first: missing several security headers, no robots.txt or sitemap, and incomplete email security.

Launched on Hacker News on August 20, 2026. The site is hosted on Render and served through Cloudflare, with a domain registered in 2023. We've detected 5 technologies on this site, covering analytics, CDN, CSS frameworks, and web fonts. The stack includes Tailwind CSS, Cloudflare, and Cloudflare Web Analytics.

It's running the same core stack as 632 other 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.
