Diagnostic tool for the whole company

Eliminate the guesswork from support tickets

Stop asking users for screenshots of the Network Tab. Witnes gives your CS team an X-ray link to see exactly why a session was slow — Wi-Fi, API, or frontend.

The Evidence

Every session. Every load. Every clue.

Each user gets a dedicated timeline at /org-id/user-id showing a 7-day chronological history of every interaction.

Instantly spot patterns: Was Monday #4 slow because of their network, or was it your API? The answer is one click away.

The 3 Pillars of Failure

We track the three places things go wrong

Most tools just tell you "it's slow." Witnes tells you "it's slow because of [X]."

Wi-Fi Speed

User-side

We measure the user's effective connection speed at the time of every interaction. Know instantly if a complaint is about their 2 Mbps coffee-shop Wi-Fi — not your infrastructure.

  • Effective bandwidth
  • Connection type (4G, Wi-Fi, etc.)
  • RTT to origin

API Latency

Server-side

Every XHR, fetch, and WebSocket call is tracked with TTFB, total duration, and status code. Identify that one endpoint that takes 8 seconds before the user even finishes describing the problem.

  • Time to First Byte
  • Total response time
  • HTTP status codes

Frontend Render

Client-side

We capture Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift for every page load and SPA transition. If the UI is janky, you'll know why.

  • LCP / FID / CLS
  • SPA transition time
  • JS long tasks

For Developers

Two lines of code. Zero config.

Drop in our lightweight JS snippet and call identify() when a user logs in. That's it. We handle the rest — page loads, SPA transitions, API heartbeats, and Web Vitals.

app.js index.html 
// 1. Add the snippet to your <head>
import Witnes from '@witnes/sdk';

// 2. Identify the user on login
Witnes.identify({
  orgId: "acme-corp",
  userId: "user-4821",
});

// That's it. We handle everything else.
