k6 load and performance testing services
Load, stress and spike testing with k6 for APIs and web apps.
DeviQA provides k6 load and performance testing services, running load, stress and spike tests for APIs and web applications inside CI/CD pipelines. For The Mortgage Office, DeviQA added 10 k6 load scenarios to CI, and for XDEFI it created 70+ performance scripts with k6 and JMeter.

When k6 for load testing is the right choice
You need to simulate real-world traffic and test performance under heavy load.
You want fast, scriptable load tests using JavaScript and modern dev workflows.
You’re running microservices or APIs and need accurate, developer-friendly performance tests.
You’re integrating load testing into CI/CD for continuous performance validation.
You want to catch bottlenecks early without relying on heavyweight enterprise tools.
You’re scaling fast and need proof your infrastructure can handle the pressure.
You need a modern, open-source alternative to legacy performance testing tools.
k6-based load testing services
From strategy to scripting and CI/CD integration, we help you build and scale reliable load testing with k6.
k6 performance testing strategy
We define load models, target metrics and pass/fail thresholds based on your real traffic and SLAs.
k6 framework setup
We set up k6 scripts, test data, environments and Grafana dashboards for your stack.
Load, stress, spike and soak testing
We run each test type to find limits, breaking points and memory leaks before release.
API and microservices load testing
We script realistic user journeys across REST, GraphQL and WebSocket APIs.
Integrating tests into CI/CD pipelines
We connect k6 with your CI/CD tools — such as Jenkins, GitLab, or GitHub Actions — for automated performance testing at every stage.
k6 test support & maintenance
We keep your k6 tests up to date as your system evolves and provide ongoing support to ensure sustained performance insights.
Can’t find engineers who truly know k6 inside out?
