What it does

Relay provides privacy-first link analytics, allowing startup founders to track conversions and perform A/B testing without compromising user data.

When to use it
  • When you need to track link clicks and conversions without using cookies
  • When you want to perform A/B testing with device and geo routing
  • When you need to integrate link analytics with Facebook, Google Analytics 4, or Google Tag Manager retargeting
Ready-to-paste prompt
Create a new link with A/B split testing: `https://your-relay-url/ab-test?route=device&url1=https://example1.com&url2=https://example2.com`
Heads up: Make sure you have a Cloudflare account and have enabled Cloudflare Workers and D1 to use Relay, as it relies on these services for hosting and data storage
