Ensure Peak Performance and Scalability with API Load Testing

API Load Testing

Simulate thousands of concurrent API calls to test response times, throughput, latency, and error rates under expected and peak user loads.

API Stress Testing

Push APIs beyond capacity limits to identify system-breaking thresholds, memory leaks, and scalability issues.

Performance Benchmarking & Monitoring

Benchmark API speed and response consistency under varying conditions and track performance regressions across builds.

Your APIs Should Work — Even at Peak Traffic

Identify weak points in your API infrastructure and ensure stability across production loads.

Frequently Asked Questions (FAQs)

It involves simulating user traffic and API calls at scale to test response time, error rates, latency, and throughput.

Microservices rely on API chaining. Load testing ensures each API handles its share without causing failures upstream or downstream.

We monitor response time (p50/p90), errors, throughput, concurrency, memory/CPU usage, and SLA breaches.

No. We test on staging/pre-prod environments and throttle loads when working with sensitive services.

Yes. We integrate k6, JMeter, or custom scripts into Jenkins, GitHub Actions, or Azure DevOps for continuous performance monitoring.

Yes. We load-test GraphQL queries/mutations, REST/SOAP endpoints, and partner APIs under load.
