Hey is a command-line utility designed for HTTP load testing and API performance benchmarking. It functions as a concurrent request generator that simulates high volumes of traffic against target endpoints to evaluate service responsiveness, throughput, and stability under load.
The tool distinguishes itself by integrating specialized modules for cryptographic request signing and internal service authorization. It supports the generation of digital signatures for decentralized social protocols and validates backend requests using shared secret tokens, allowing for secure interaction with protected or decentralized network environments.
To ensure diagnostic accuracy, the utility employs histogram-based latency aggregation to calculate precise performance percentiles. It maintains consistent request patterns through a managed worker pool and connection pooling, which minimizes overhead during high-frequency testing. The software is distributed as a static binary to ensure consistent execution across different operating systems.
