Sample Size Calculator for A/B Tests (client-side, no dependencies)
by dj-trondheim·Mar 6, 2026·1 point·0 comments
AI Analysis
●Mid
A/B test calculator, but this already exists in Optimizely, VWO, and dozens of free tools.
Strengths
- •Zero dependencies and no signup makes it frictionless to load and use once
- •Explains the underlying statistical formula (two-tailed z-test) alongside the calculator
- •Client-side computation means no data transmission or tracking concerns
Weaknesses
- •No differentiation: Optimizely, VWO, and 50+ free calculators do this identically
- •Single-page utility with no chaining, no novel approach, no reason to bookmark
