CFP Radar

A radar for open tech CFPs. Filtered, ranked, and matched to your talk.

Added April 28, 2026 · Last analysed April 28, 2026 · via Hacker News · 67% 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 28 April 2026; the live site may have changed since.

CFP Radar has the basics covered well, with a thorough launch checklist and clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Hacker News on April 27, 2026. The site is hosted on Vercel, with a domain registered 1 day before launch. Our crawler found 7 technologies on this site, covering analytics, CSS frameworks, DNS providers, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 10,671 other launches.
