Raah offers a revolutionary approach to API performance monitoring by capturing real-world network telemetry directly from users' browsers. Unlike traditional synthetic probes, Raah provides complete visibility into how APIs perform in the wild, offering insights into the 'last mile' of network interactions. This tool sits in the browser, collecting high-fidelity telemetry on every network interaction, and sends this data to a Cloudflare Worker for enrichment with ISP, city, and country information.

Key Features

• Real User Monitoring: Captures every fetch() and XHR from actual browsers in real-time.

• ISP-Level Breakdown: Pinpoints which ISPs are bottlenecks, offering insights beyond country-level performance.

• Privacy-First Design: No cookies or user tracking, with minimal PII collection.

• Framework Agnostic: Works seamlessly with React, Vue, Svelte, or vanilla JS.

• Core Web Vitals: Provides real user scores for metrics like LCP, CLS, and FCP.

Raah is designed to be non-blocking and lightweight, with a script size of just ~2kb gzipped. It offers a drop-in reliability solution that requires no SDK, build step, or agents to install, making it compatible with any tech stack. This makes Raah an essential tool for developers looking to optimize user experience by understanding the real-world performance of their APIs.
