Real-browser performance testing
Evaluat runs each virtual user in an isolated real browser and reports Core Web Vitals, Navigation Timing, and Apdex under load, with session video, network logs, and console logs for every user.
Choosing a load tool is a buyer decision: which product answers the peak-traffic experience question for your site, and which one belongs in protocol or API capacity work. Here is where each fits, written as fairly as we can manage.

Evaluat runs each virtual user in an isolated real browser and reports Core Web Vitals, Navigation Timing, and Apdex under load, with session video, network logs, and console logs for every user.
Loadium Loadium is a commercial cloud load-testing platform from Testinium that uploads and runs existing open-source scripts (Apache JMeter, Gatling, Selenium WebDriver) plus HTTP, API, and Postman-converted tests, scaling to millions of virtual users across many global zones. Its reporting centers on response time, throughput, hits, and errors.
The categorical difference: Loadium is a cloud runner for open-source engines: you upload existing JMeter, Gatling, or Selenium scripts and it runs them at scale, reporting response time, throughput, and errors. Evaluat runs a real browser for every virtual user with no scripts, reports Core Web Vitals and Apdex, and can generate an Executive Summary.

*Executive Summary is not available on the Starter plan.
You have existing JMeter, Gatling, or Selenium scripts and need protocol load at scale. Loadium runs them in the cloud with no rewrite, scaling to millions of virtual users across many zones. Evaluat does no protocol or API load and does not run uploaded scripts.
You need behind-the-firewall load or APM integration. Loadium offers private Docker load locations and integrates with New Relic, AppDynamics, Datadog, and Instana. Evaluat is a hosted browser-testing product.
You want web performance metrics without writing or uploading scripts. Evaluat scenarios are built in a visual step editor with no scripts, and every run reports LCP, INP, CLS, plus FCP and an Apdex score. As of the published date, Loadium needs an uploaded JMeter, Gatling, or Selenium script, and its Selenium path returns navigation timing only, not Core Web Vitals.
Your stakeholders need the result, not the raw numbers. Evaluat can distil a run into an Executive Summary: a plain-language verdict with a health score, the key findings ranked by severity, and recommended fixes. Loadium gives you metric graphs and tables, with PDF and Excel export, to interpret yourself.
You need per-session detail, not aggregate metrics. Evaluat keeps session video, full network logs, console output, and step-by-step pass and fail for every virtual user. Loadium reports aggregate response time, throughput, and errors, without per-session video or console.
You need data residency. Evaluat keeps test data in the region the test ran in, with live test regions in the UK and the EU. Loadium offers region selection and private locations, which is not the same as a data-residency commitment.
As of the published date, no. Loadium reports response time, throughput, hits, and errors. Its Selenium path returns navigation-timing only, not Core Web Vitals. Evaluat reports Core Web Vitals (LCP, INP, CLS), plus FCP, for every run.
Yes. Loadium runs uploaded JMeter, Gatling, or Selenium scripts, and even its Record and Play extension records HTTP traffic into a JMeter .jmx, not a rendered journey. Evaluat records a real-browser journey with no scripts.
After a test, you can generate an Executive Summary: a plain-language verdict with a health score, the most important findings ranked by severity, and recommended fixes, grounded in the run's Core Web Vitals, Apdex, error rates, and slowest URLs. It turns a dense report into a two-minute read you can share with stakeholders.
No. Evaluat builds tests with its own no-code recorder and tests in the real browser. To run existing JMeter, Gatling, or Selenium scripts at protocol scale, Loadium is the right runner.
No. Evaluat tests user-facing web applications in the real browser. Protocol and API load is a different layer, outside what Evaluat does.
Yes. Every virtual user has session video, full network logs, console output, and step-by-step pass and fail status. When a run regresses you can watch the exact session that failed instead of inferring it from aggregate charts.
For real-browser experience under load with no scripts, yes. Protocol and API load from existing scripts is outside what Evaluat does.
