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.
No credit card required. Full retention for 7 days.

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-sideWe 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-sideEvery XHR and fetch call is tracked with TTFB and total duration. Identify that one endpoint that takes 8 seconds before the user even finishes describing the problem.
- Time to First Byte
- Total response time
- Server processing gap
Frontend Render
Client-sideWe capture Largest Contentful Paint and Cumulative Layout Shift for every page load and SPA transition. If the UI is janky, you'll know why.
- LCP / 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 waterfalls, and Web Vitals.
// 1. Add the snippet to your <head>
<script>
window.witnesConfig = {
projectKey: 'YOUR_PROJECT_KEY',
};
</script>
<script src="https://cdn.witnes.io/w.min.js" async></script>
// 2. Identify the user on login
// TypeScript
(window as any).Witnes?.identify?.("user-4821");
