Our solutions for your load and stress testing challenges

Prevent crashes. Expose bottlenecks. Scale with confidence. Our load and stress testing solutions keep your app fast - even at peak traffic.

App crashes under peak traffic

Challenge

53% of users leave if an app loads in over 3 seconds.

Solution

We simulate real traffic spikes to uncover weak points, so you can fix them before users notice.

Scalability issues during growth

Challenge

80% of performance problems stem from poor scalability.

Solution

We test across load patterns to help you scale smoothly, without overpaying for infrastructure.

Complex systems cause hidden failures

Challenge

Microservices often hide bottlenecks and latency.

Solution

We replicate your full environment to catch slow APIs and fragile integrations early.

Load testing slows your releases

Challenge

Teams often skip it due to tight deadlines, risking outages.

Solution

We automate testing in your CI/CD pipeline for faster, safer releases.

The scope of our load and stress testing services

From steady traffic to sudden spikes, we stress every layer of your system, so you’re prepared when it counts.

Smoke testing

We validate system stability under minimal load to catch critical issues before deeper testing begins.

Average-load testing

We simulate typical user traffic to ensure your app delivers consistent, reliable performance under normal conditions.

Stress testing

We push your system to (and beyond) its limits to identify breaking points and assess how gracefully it fails.

Spike testing

We simulate rapid traffic surges to ensure your infrastructure can absorb sudden demand without crashing.

Breakpoint testing

We gradually increase load to pinpoint when performance starts to degrade, so you can fix issues before they hit production.

Soak testing

We apply sustained load over time to uncover memory leaks, resource exhaustion, and long-term stability risks.
