Open toolUse the output with context
Plan load before it becomes an incident.
Translate latency, traffic and concurrency assumptions into load-test targets and capacity decisions your team can review.
- Estimate RPS and virtual users from closed-workload assumptions.
- Model API throughput, burst traffic and rate-limit pressure.
- Turn target traffic into instance, CPU, node and thread-pool estimates.
