Powered by k6.io

We use k6.io - the modern load testing tool that developers actually love. JavaScript-based, developer-friendly, and incredibly powerful.

Why k6.io is the Best Choice

Developer-First Approach

Write tests in JavaScript, not some proprietary language. Use your existing development tools and workflows.

Real Browser Performance

Test real HTTP/2, WebSocket, and browser performance. Not just synthetic metrics, but actual user experience data.

CI/CD Integration

Run performance tests in your CI/CD pipeline. Catch performance regressions before they reach production.

k6.io Performance Testing

The only tool you need for comprehensive performance testing

  • +Load testing with realistic user scenarios
  • +Stress testing to find breaking points
  • +Spike testing for traffic bursts
  • +Endurance testing for long-term stability
  • +Volume testing with large datasets

Performance Testing Types

Comprehensive performance testing using k6.io to ensure your application can handle any scenario

Load Testing

Test your application under expected normal load conditions. Ensure it performs well with typical user traffic.

  • +Normal user load simulation
  • +Response time validation
  • +Throughput measurement

Stress Testing

Push your application beyond normal limits to find the breaking point. Understand how it behaves under extreme conditions.

  • +Breaking point identification
  • +Recovery behavior testing
  • +System stability validation

Spike Testing

Test how your application handles sudden traffic spikes. Perfect for e-commerce sites during sales or viral content scenarios.

  • +Sudden traffic spike simulation
  • +Auto-scaling validation
  • +Graceful degradation testing

Frequently Asked Questions

Common questions about our performance testing services.

Do you provide load and stress testing services?

Yes. AssertQA provides load, stress, and scalability testing services that simulate real traffic so you know exactly how your application behaves under pressure before your users do.

Which performance testing tools do you use?

We primarily use k6.io for performance testing, building realistic load scenarios that integrate cleanly into modern development and CI/CD workflows.

How do you identify performance bottlenecks?

We measure response times, throughput, and resource usage under load, then pinpoint the slow queries, endpoints, and infrastructure limits that cause bottlenecks and recommend concrete fixes.

Can you test whether our application scales before a major launch?

Absolutely. We run scalability tests that model peak launch traffic so you can confidently handle spikes, sales events, or marketing campaigns without downtime.

Do you integrate performance tests into our CI/CD pipeline?

Yes. We can automate performance tests inside your CI/CD pipeline so performance regressions are caught continuously, not just before release.

Do you use AI in your performance testing work?

Yes, we use AI as much as it genuinely helps, for example to spot anomalies in load results faster. But AI doesn't do the work for us. Our engineers design the scenarios and interpret every result.
