Server response time isn't user experience.
The number that matters is what the browser paints. Everything else is a proxy for that, and most proxies are wrong at peak.
About
Built because the existing tools couldn't tell us what we needed.
Evaluat is a real-browser performance testing platform. We started building it because we got tired of "all green" load test reports that didn't predict the production incidents that actually mattered.
What we believe
Six core beliefs we keep coming back to.
The numbers should match what the customer sees.
If your test report says the page loads in 800ms and the customer sees 6 seconds, the test report is the broken thing. Not the customer.
Forensic detail beats aggregate percentiles.
When something breaks for 14 users out of 42,000, p99 won't show it. You need to open the session for one of those 14 and watch what happened.
Pre-launch software shouldn't pretend to be a brand.
This site is intentionally restrained. The product talks. We're not interested in graphics that promise revolution.
Demo-led beats demo-canned.
Every demo is on your real site, not ours. The report is yours to keep whether you sign up or not.
Build once. Use everywhere.
The scenario you write for a performance test should also be your CI smoke test and your continuous monitor. Three products, one foundation.
Where we are
UK-based. Customer-led.
Evaluat is a real-browser performance testing platform built by Evaluat Digital Limited, a company incorporated in the United Kingdom. Our test infrastructure runs from EU regions, with EU- or UK-only data residency available on request. That matters to most of our customers, who are SaaS and e-commerce engineering teams in the European Union and the United States. The platform captures Web Vitals, network logs, console output, and session video for every virtual user, so engineering teams get forensic, per-session evidence for performance regressions instead of aggregate percentiles. We're a small team, and every roadmap conversation starts with a customer demo call. Each demo runs on the customer's real site, and the resulting performance report is theirs to keep whether they sign up or not.
