Unlimited Stress Testing Documentation
Higher concurrency speeds up stress testing but makes debugging harder. Use 1-10 for debugging, 50-100+ for stress testing.
Runs calls one by one for easier debugging and tracing. Slower but sequential logs help identify issues.
Adds randomized delays between calls for more realistic testing. Simulates variable network conditions and timing.

The Python Webhook Simulator is a powerful tool that replicates and enhances all functionality from the original HTML/JS version, with unlimited concurrent requests for stress testing.
Unlike browser limitations (~6 concurrent requests), this Python version can handle unlimited concurrent calls for true stress testing.

Multiple calls run simultaneously for maximum performance and stress testing.

✅ Faster execution, ideal for stress testing
Calls run one after another for controlled testing and debugging.
python webhook_simulator.py \ --url https://api.example.com/webhook \ --agents 101001,101002 \ --calls 100 \ --sequential \ --preset inbound-success
✅ Controlled execution, easier to debug
Example: 100 calls, each taking 1.5 seconds
Concurrent (--concurrent 20):
~7.5 seconds total
Sequential (--sequential):
~150 seconds total

Shuffle mode now works without presets and creates truly random call scenarios for ultimate robustness testing.
