CloudQA Load and Performance Testing

Load Testing with Real Browsers, as a Service

Find out how your web application holds up before a launch, a sale or a big release. We replay your key user journeys in many real browsers at once and show you where response times slip and where your servers break.

What is real-browser load testing?

Real-browser load testing puts your web application under heavy traffic using real browser sessions instead of simulated HTTP requests. Each virtual user loads pages, runs JavaScript and clicks through a journey just as a customer would. The results show what users actually experience as load grows: page response and render times, failed steps and errors.

CloudQA load testing is a service we run on request. We take the user journeys you have already built in CloudQA, or record them with you, then run a mix of those scenarios on many browsers at once over a short period.

What a load test tells you

Where performance slips

The traffic level at which response and render times start to rise.

Your breaking point

How much load your servers take before journeys fail or time out.

What degrades first

Which journeys, pages and steps slow down first, so you know where to focus.

Regional differences

How performance changes when load comes from different locations.

Load testing service features

Realistic, user-like load built from the same journeys you test every release.

Codeless scenarios

Record user-like actions and build single-page or multi-page workflows in minutes, or reuse your existing CloudQA tests.

Real browsers, not just protocols

Measure what users see, including render times, instead of only server response times at protocol level.

UX-driven results

Map your application’s performance along each user journey, step by step.

Scenario mix and think time

Combine journeys such as browsing, search and checkout, with pauses that mimic real reading time.

Multiple data sets

Run each workflow with different data so the test reflects real usage.

Multiple locations

Generate load from several geographic locations.

Export to JMeter

Convert workflow scripts to JMeter scripts in minutes for protocol-level, virtual-browser testing.

Cloud test nodes

CloudQA creates isolated, thread-safe containers across cloud test nodes, so each session behaves like a real user.

Scheduled around you

Run the test at a time and frequency that suits your release plan, with no expensive licences or long-term commitments.

How a load test engagement works

Tell us what is coming

A launch, a sale, a migration or a big release. Share your goals, expected traffic and key journeys.

We prepare scenarios

We reuse your CloudQA journeys or record them with you, and agree the scenario mix and test data.

We run the test

Many real browsers run the scenarios at once, ramping load up over a short period.

You get the results

Response and render times, errors and the point where performance breaks, walked through with our team.

Protocol-level vs real-browser load testing

Both have a place. CloudQA runs real-browser tests and can also export journeys to JMeter when you need protocol-level volume.

Real-browser load testing

Measures what users actually experience

  • Runs JavaScript and renders pages like a real visitor
  • Finds front-end and third-party bottlenecks, not just server ones
  • Scenarios built from recorded journeys, without code
  • Results map directly to steps in a user journey
Protocol-level load testing

Measures server response to raw requests

  • Sends HTTP requests directly, with no browser
  • Lighter per user, so it can generate very high volume
  • Does not execute JavaScript or measure rendering
  • Scripts need updating whenever requests change

Load testing FAQ

Is CloudQA load testing self-service?

No. Load testing is a service we run on request. Our team prepares the scenarios with you, runs the test and walks you through the results.

Why test with real browsers instead of protocol-level tools?

Real browsers run JavaScript and render pages, so the results reflect what users actually see, including front-end and third-party slowdowns that protocol-level tests miss.

Can I reuse my existing CloudQA tests?

Yes. Journeys you have recorded for regression testing can be reused as load test scenarios, combined into a realistic mix with different data.

Can CloudQA export load scripts to JMeter?

Yes. Workflow scripts can be converted to JMeter scripts for protocol-level, virtual-browser testing.

How do I request a load test?

Contact us with what you are preparing for, your expected traffic and the journeys that matter most, and we will scope the test with you.
