Raah – Real-world network telemetry for API performance

Summary: Raah captures real user network telemetry to reveal API performance issues without relying on synthetic probes. It collects browser-side data including DNS, TCP, TLS, TTFB, Core Web Vitals, and performance breakdowns by ISP or region to help diagnose slowdowns between the browser, network, and backend.

What it does

Raah gathers real-world network metrics from actual users to provide detailed insights into API and frontend performance. It analyzes browser-side network events and categorizes data by ISP and region.

Who it's for

Raah is designed for developers and teams working on apps, APIs, frontend, or infrastructure who need to understand network performance issues.

Why it matters

It addresses the challenge of identifying network-related slowdowns by providing visibility into real user experiences beyond synthetic monitoring.
