Calyxa — the math tutor that lives on your screen
Calyxa sees the problem on your screen and talks you through it — never the answer, just the step you're missing.
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 21 July 2026; the live site may have changed since.
Calyxa — the math tutor that lives on your screen is partway there, with complete legal pages and a thorough launch checklist. Main gaps: missing several security headers, no robots.txt or sitemap, and incomplete email security.
The site is hosted on Vercel and served through Cloudflare, with a domain registered the day of launch. The crawl picked up 12 technologies on this site, covering security, analytics, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.
For context, it's on one of the most common stacks we track, shared by 13,753 launches.
