Website Monitoring: Because Observability starts at the fingertips of your users

Websites are fast… until they aren’t. And when they break, the users feel it immediately: slow clicks, broken forms, or worse—empty pages and rage quits. The worst part? You often don’t know it’s happening until someone complains. Too late.

Dash0 Website Monitoring is here to fix that.

We’re giving you full visibility into how real users experience your website: session by session, request by request. You’ll know what happened, where, and why, before support even opens a ticket.

As a matter of course, the Dash0 Website and the Dash0 UI were the first two web applications ever monitored by Dash0’s Website Monitoring.

One Click. Full Context.

Every user session is a haystack of clicks, transitions, requests, and timing quirks. Finding the needle—the moment that breaks UX—is what Dash0 does best.

  • Web Vitals? Captured.
  • Backend errors and slowdowns? Traced to the source, doesn’t matter how deep in the system.
  • Drop-offs? Mapped to real journeys.

We don’t just tell you something went wrong. We show you exactly who it affected, where they clicked, what API it hit, and which service timed out.

All that is going on to serve a time series to our Marcel in Dash0: from the browser to the Prometheus Query engine, in one seamless go.

No guessing. No tab-hopping between frontend logs and backend traces. Just answers.

Visualize the Journey, Spot the Cracks

A bounce rate is a symptom. Dash0 helps you diagnose the cause.

We track the full path—from first page load to final tab switch—and light up the moments that mattered:

  • That 3-second LCP on mobile? You’ll see the image that stalled it.
  • That weird layout shift mid-scroll? You’ll know which ad pushed the content.
  • That sudden exit? You’ll catch the failed request before they hit the back button.

Whether the issue’s in React hydration, third-party scripts, or buried four microservices deep—you’ll see it. And Triage on Web Events points you directly to the issues:

Triaging web events that make up the user sessions has the same familiar experience as Triage for logs or spans, and provides the same level of awesome value.

Backend Bottlenecks, Frontend Fallout

If a database implodes and your monitoring does not catch it, does the user see an error?

Yes, yes they very much do.

What happens in the backend does not stay in the backend. That slow cart database call to retrieve user preferences? It's why the checkout page takes forever. Dash0 stitches together the entire interaction chain—so you can see how every backend hiccup hurts the frontend.

  • Trace every request.
  • See frontend impact.
  • Fix what actually slows your users down.

Every single request is related to the original user session. You can even evaluate the impact of any backend error in terms of how many user sessions it affects, and even Triage on it, both in terms of web events, and in terms of spans!

You can filter tracing data based on whether its trace originates from Website Monitoring or not, and you can even triage on it and see how errors cluster around sessions!

From an engineer to another, let me tell you: knowing how a mistake affects real users is a transformative experience. And now, every single backend engineer can have that, irrespective of whether they work on the APIs directly powering the backend, or on dependencies far removed.

Troubleshoot Poor Web Vitals Like a Pro

Need to know which sessions are getting crushed by layout shifts or slow inputs? Dash0 makes it easy to filter by pain—LCP, INP, CLS—and drill into affected sessions fast.

You don’t need to guess where your SEO is bleeding. You’ll see it:

The Web Vitals of the Dash0 website. All is good.

Real Users. Real Issues. Solved Fast.

You don’t need another dashboard. You need to know why users are dropping, where performance is spiking, and what to fix it—now.

Dash0 Website Monitoring gives you the signal and the context—all in one place.
