Here is where each fits, written as fairly as we can manage. Reviewed 19 July 2026 Competitor claims reflect publicly available vendor materials reviewed on that date. ![Evaluat logo](https://www.evaluat.com/favicon.svg) Evaluat ### 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. ![Loadium logo](https://www.evaluat.com/logos/competitors/loadium.png) Loadium ### Cloud runner for JMeter, Gatling, Selenium 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. At a glance ## Capability comparison | Capability | Evaluat | Loadium | | ------------------------------------------------- | ------- | ---------------------- | | Real browser per virtual user | Yes | Navigation timing only | | No-code scenario builder | Yes | Partial | | Core Web Vitals (LCP, INP, CLS) under load | Yes | No | | Apdex score | Yes | Via uploaded JMeter | | Executive Summary | Yes | No | | Per-session video for every user | Yes | No | | Full network and console logs per session | Yes | No | | Step-by-step pass/fail playback | Yes | Partial | | UK and EU infrastructure | Yes | Partial | | HTTP / API / protocol load at scale | No | Yes | | Runs existing JMeter / Gatling / Selenium scripts | No | Yes | | Private / on-premise load locations | No | Yes | \*Executive Summary is not available on the Starter plan. *** When Loadium is the right call ## Loadium is genuinely the better tool in a couple of situations. **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. *** When Evaluat is the right call ## Evaluat is the no-script path to web performance. **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. Common questions ## FAQ ### Does Loadium measure Core Web Vitals? 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. ### Do I have to upload scripts to Loadium? 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. ### What is the Executive Summary? 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. ### Can Evaluat run my JMeter or Selenium scripts? 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. ### Can Evaluat do protocol or API load like Loadium? No. Evaluat tests user-facing web applications in the real browser. Protocol and API load is a different layer, outside what Evaluat does. ### Does Evaluat keep a record of every virtual user? 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. ### Is Evaluat a replacement for Loadium? For real-browser experience under load with no scripts, yes. Protocol and API load from existing scripts is outside what Evaluat does.
