Concurrents
How many parallel test slots you can run. Use more for multi-endpoint or multi-region windows — not just “more power.”
PRICING
Choose capacity for authorized stress testing
Clear limits: concurrent tests, max runtime, and estimated L4/L7 throughput. Every plan is for infrastructure you own or are explicitly authorized to test.

Throughput (Gbps / RPS) is an estimate tied to concurrency — size to your hypothesis. Verified targets only.
How to pick a plan
Max runtime
Longer windows help soak tests and step-ramps. Short runs are fine for smoke checks and edge probes.
Stress tests per day
Every plan includes unlimited stress tests per day — run as many authorized sessions as you need within your concurrent and runtime limits.
Throughput estimates
Gbps / req/s lines are capacity estimates tied to concurrency — size to your hypothesis, not the banner number alone.
