Confidence
A simple confidence calculator for A/B tests. Calculate confidence levels, p-values, power, uplift, visitor needs and Bonferroni-adjusted thresholds without pretending you need to be a data scientist.
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 25 June 2026; the live site may have changed since.
Confidence still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Hacker News on June 25, 2026. The site is hosted on Fastly in the United States. The crawl picked up 4 technologies on this site, covering CDN, hosting, javascript library, and package cdn. The stack includes Chart.js, Fastly, and GitHub Pages.
For context, it's on one of the most common stacks we track, shared by 1,345 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 |
|---|---|
| AI writing signals | +5 |
| AI code-structure signals | +5 |
| AI CSS signals | +15 |
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.
