LoadRunner CloudEvaluat's answer
Evaluat runs each virtual user in its own isolated real browser instance, not a shared browser and not a protocol-level HTTP script. That means it measures Core Web Vitals (LCP, INP, CLS) and Navigation Timing while the site is under load, and it records session video, network logs, and console logs for every virtual user. When a page slows or breaks at peak, you don't get a percentile; you open the exact session, watch the video, and read the request that stalled.
Evaluat's answer
Most load testing tools work at the protocol level: they fire HTTP requests and measure server response times, but they never render the page, so they cannot see JavaScript execution, hydration, or Core Web Vitals. Browser-based alternatives often share browser instances across virtual users, which contaminates timing metrics. Evaluat gives every virtual user an isolated real browser, so the numbers reflect what a person actually experiences. Scenarios are built in a visual editor with no scripting. Honest boundary: for raw API concurrency with no rendering, a protocol tool like k6 or JMeter is the lighter instrument.
Evaluat's answer
Engineering, QA, and digital leaders at ecommerce and transaction-heavy web businesses who need to know their site survives peak traffic, plus the agencies that build and maintain those stores. Typical users are teams rehearsing Black Friday or a product launch, teams that invested in frontend performance and need proof it holds under load, and Magento, Shopify, and headless storefront teams whose customer experience is decided in the browser rather than at the server.
Evaluat's answer
Evaluat was built because the existing tools couldn't tell us what we needed. Running high-traffic ecommerce platforms, the team kept seeing the same gap: protocol load tests reported healthy server response times while real customers on real devices had a slow, broken experience the tools never rendered. Evaluat (Evaluat Digital Limited, founded 2022, London) was built to close that gap by making the browser, not the server response, the unit of measurement.
Evaluat's answer
Each virtual user runs in an isolated browser instance on cloud infrastructure. Test scenarios are built in a visual no-script editor, and results capture Core Web Vitals, Navigation Timing, session video, network logs, and console logs. The platform is agent-ready: it exposes an OpenAPI-documented API and a public MCP server so AI assistants can run its free website speed test directly.
