Cold Plunge Calc
A free training system that checks your risk, calculates a safe plunge time for your water temperature and goal, then builds a week-by-week plan toward the roughly 11 minutes a week that regular cold-water swimmers tend to accumulate.
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 27 June 2026; the live site may have changed since.
Cold Plunge Calc scores well across the board, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.
Launched on Product Hunt on June 27, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 3 days before launch. We've detected 11 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
It's on one of the most common stacks we track, shared by 3,045 launches.

Readiness Breakdown How?
Performance How?
Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.
Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| Placeholder branding | +10 |
| AI writing signals | +5 |
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.
