oha is a small HTTP load generator written in Rust, inspired by rakyll/hey, that sends load to a web application and displays results in a realtime TUI animation. It supports HTTP/1, HTTP/2, experimental HTTP/3, and installs via cargo, package managers, or prebuilt binaries.

Use cases

• load test my http api
• benchmark a web server from the command line
• stress test an endpoint with concurrent requests
• alternative to hey or ab for http load testing
• visualize request latency in a terminal while load testing
• test http2 performance of my service

When to choose

• you want a fast, single-binary CLI load tester with a realtime TUI
• you need HTTP/2 or experimental HTTP/3 support in a load generator
• you prefer a hey-like tool written in Rust with active maintenance

When to avoid

• you need distributed load generation across many machines
• you require scripted, complex test scenarios rather than simple request load
• you need a GUI or CI-friendly non-interactive reporting only
