Comparison

Evaluat vs JMeter

Both tools load-test applications. They go about it very differently. Here's where each one fits, written as fairly as we can manage.

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.

JMeter

Open-source protocol load testing

Apache JMeter is the veteran open-source load testing tool, with the broadest protocol coverage here (HTTP, JDBC, JMS, FTP, SOAP, TCP, and gRPC via plugins). Its WebDriver Sampler, a community plugin, drives a real browser via Selenium, though JMeter's own guidance recommends it only for small-scale browser metrics, not high-concurrency load.

The categorical difference: JMeter is the veteran open-source load tester, with the broadest protocol coverage of any tool here. Its WebDriver Sampler plugin can drive a real browser via Selenium, but it is resource-heavy and meant for small-scale checks. Evaluat runs a real browser for every virtual user with no plugins or scripting, and reports Core Web Vitals, Apdex, and an Executive Summary.

When JMeter is the right call

JMeter is genuinely the better tool in a couple of situations.

You need free, self-hosted load testing with the broadest protocol coverage. JMeter is open source and tests HTTP, databases via JDBC, JMS queues, FTP, SOAP, TCP, and more, with a twenty-year ecosystem (Jenkins, Taurus) behind it. Evaluat is a hosted commercial tool focused on the browser.

You want distributed protocol load at scale with mature reporting. JMeter runs distributed injectors and produces an HTML dashboard with percentiles and an Apdex table. For backend and protocol capacity testing, that is its home ground.

When Evaluat is the right call

Evaluat runs a real browser, not a plugin per thread.

You want real-browser metrics for every user, without a plugin or scripts. Evaluat runs a real browser for every virtual user and reports LCP, INP, CLS, FCP, and Apdex, recorded by clicking through your site. JMeter's WebDriver Sampler is a community plugin that runs one resource-heavy browser per thread, and JMeter's own guidance warns against it for large-scale load.

Your stakeholders need the result, not the raw numbers. Evaluat distils each run into an Executive Summary: a plain-language verdict with a health score, the key findings ranked by severity, and recommended fixes. JMeter gives you an HTML dashboard of charts and tables to interpret yourself.

You need to debug failures forensically. Evaluat keeps session video, full network logs, console output, and step-by-step pass and fail for every virtual user. JMeter reports aggregate results, with no per-session video or browser console.

You want a hosted tool with data residency, not infrastructure to run. Evaluat is hosted and keeps each test's data in the region the test ran in. JMeter is software you host, distribute, and scale yourself.

Common questions

FAQ

Can JMeter test real browsers?

Yes, through the WebDriver Sampler, a community plugin that drives a real browser via Selenium. But it runs one resource-heavy browser per thread, and JMeter's own guidance recommends it only for small-scale browser metrics, not high-concurrency load. Evaluat runs a real browser for every virtual user as standard.

Does JMeter measure Core Web Vitals?

No. JMeter reports protocol response times and, in its HTML dashboard, an Apdex score. It has no native Core Web Vitals. Evaluat reports LCP, INP, CLS, and FCP.

Does JMeter have an Apdex score?

Yes, JMeter's HTML dashboard computes an Apdex table, and so does Evaluat. Evaluat measures it from a real browser alongside Core Web Vitals.

What is the Executive Summary?

After a test, Evaluat produces 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 do protocol, database, or API load like JMeter?

No. Evaluat tests user-facing web applications in the real browser. Protocol, database, 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 JMeter?

For real-browser experience under load with no plugins or scripting, yes. Protocol, database, and API load is outside what Evaluat does.
