Stop Paying $10/Month for Vercel Speed Insights – Cloudflare Web Analytics + Free Worker

说明与用途

使用免费的 Cloudflare Web Analytics 和 Cloudflare Worker 收集每页 Core Web Vitals，摆脱每月 $10 的 Vercel 订阅。

问题

A hobby dashboard exceeded Vercel Speed Insights free quota, forcing a $10/month upgrade for continued analytics.

结果

Per‑page Core Web Vitals are captured for $0 using Cloudflare Web Analytics and a free Worker, eliminating the $10/month Vercel subscription.

工作流

• 1. Add a Cloudflare Worker to the project (free tier, 100k requests/day).
• 2. Include the provided JavaScript snippet on each page to send web‑vitals via navigator.sendBeacon to the Worker endpoint.
• 3. In the Worker, accept POST requests, parse JSON, and log the event (name, value, page, timestamp).
• 4. View logs via Workers Logpush or tail live to see per‑page vitals.
• 5. Optionally, grep logs weekly to spot regressions.
• 6. Use Cloudflare Web Analytics dashboard for aggregate metrics; use log data for per‑page analysis.
