In the same workflow: Retry Simulator and Rate Limit Tester.

Burst Simulation

Fire all requests at once to simulate a traffic spike. See how the endpoint handles concurrent load.

Why use Burst Simulation?

Autoscaling and connection pools behave differently under sudden spikes. Fire a configurable burst of parallel requests to see how error rates and latency change—useful before launches or flash sales.

Practical tips

  • Start with tiny bursts on shared staging environments.
  • Correlate failures with 429 Detector runs to see limit surfaces.
  • Capture server-side queue depth metrics alongside client results.

Common questions

Is this stress testing?
It simulates short bursts for diagnostics, not sustained soak tests.
Why all requests from one browser?
Real users diversify clients and networks; interpret results as one data point.
