API Performance & Load Testing with Grafana k6: Playbook for Developers
Write developer-friendly load test scripts with Grafana k6 to benchmark API response times, detect memory leaks, and verify SLA limits under high concurrency.

- k6 uses Go-powered execution engines with JavaScript scripting for lightweight resource consumption.
- Define SLA thresholds (e.g. p95 < 200ms) directly in code to fail CI/CD builds automatically.
- Simulate realistic traffic spikes using ramp-up and stress test profiles.
API Performance & Load Testing with Grafana k6
Load testing validates that API infrastructure can withstand unexpected traffic surges, black friday spikes, and breaking concurrency thresholds.
**TL;DR:** Benchmark API latency and throughput using Grafana k6 scripts with automated threshold checks in CI/CD pipelines.
How does k6 differ from Apache JMeter?
k6 is developer-centric, code-driven in JavaScript, consumes significantly less memory than JMeter, and embeds cleanly into Git pipelines.
