A production-ready analytics web app that lets users analyze and compare YouTube channel performance in seconds. Built with Next.js 16 and TypeScript, Vidintel supports channel URL/handle parsing, side-by-side channel comparison, exportable reports (CSV, JSON, PDF), and a polished responsive UI with security-focused API design.
Project Overview
Vidintel is a fast, client-ready YouTube analytics platform built to turn a simple channel URL into actionable performance insights. Users can analyze one channel or compare two channels side by side, then export results as CSV, JSON, or PDF. The app emphasizes speed, clear UX, and secure server-side API handling so keys and quota-sensitive operations remain protected.
Core Technologies
Built with Next.js 16 App Router, React 19, and TypeScript, styled with Tailwind CSS. Data is fetched through secure server-side route handlers using the YouTube Data API v3. The project includes Vitest for unit/integration testing, Playwright for E2E coverage, PWA support with offline fallback, and optional Upstash Redis rate limiting to protect API quota from abuse.
