Free API Load Testing & Traffic Simulator

Simulate real-world API traffic patterns — constant load, burst spikes, auth mix, and retry amplification. Stream live results and get detailed latency, status-code, and retry reports. No signup required.

Key Features

  • Constant load, burst spike, and retry-amplification traffic patterns
  • Real-time streaming results with live latency charts
  • Latency percentiles (p50, p95, p99) and status-code breakdown
  • Auth mix testing — no-auth vs Bearer token scenarios
  • No signup required — run directly from any URL

Frequently Asked Questions

What is API load testing?

Load testing measures how your API handles concurrent traffic — response times, error rates, and throughput under real-world pressure.

Can I test my own API endpoint?

Yes. Enter any publicly accessible endpoint URL and configure traffic patterns — constant load, bursts, or retry amplification — to match your expected usage.

What traffic patterns are supported?

Three patterns: constant load (steady concurrent requests), burst spikes (sudden traffic surges), and retry amplification (cascading retries under failure).
