Oha is a modern HTTP load generator written in Rust that benchmarks web servers with high concurrency. It features a colorful terminal user interface (TUI) to visualize request metrics in real-time, similar to the classic 'hey' tool but with enhanced visual feedback.
Key Features:
  • High-performance load testing with asynchronous Rust
  • Colorful TUI for real-time metrics visualization
  • Support for various HTTP methods and custom headers
  • Detailed statistics including latency percentiles
Use Cases:
  • Benchmarking API endpoints under concurrent load
  • Validating web server performance and stability
  • Comparing performance between different server implementations
Alternatives:
  • hey – Oha provides similar functionality but with a modern TUI and Rust-based performance
  • wrk – Oha offers better terminal visualization while maintaining high performance
