Looking for Reliable Layer 4/7 Load Testing Tool with API (Performance Simulation)

Hi everyone,

I'm currently looking for a reliable Layer 4 or Layer 7 load testing tool or service for performance simulation purposes only.

Ideally, I'm looking for something that:
- Offers a clean and easy-to-use API
- Is stable and fast
- Has decent documentation or usage instructions

If anyone has experience with a tool like this (free or paid), I’d really appreciate your recommendations.

Note: This request is strictly for legitimate and ethical use — such as testing my own servers or environments I have permission to test.

For clean and reliable Layer 4 or 7 load testing with API support, you should look into tools like locust.io (good for HTTP-level simulations with a Python API) or k6 (JavaScript-based with solid performance and documentation). If you're testing lower-level protocols (TCP, UDP), hping3 or boofuzz might fit, though they’re more manual and lack polished APIs. To simulate real-world traffic diversity and avoid IP blocks during stress testing, rotating mobile proxies can help by mimicking legitimate traffic from various carriers and devices.
