oha

oha is a small program that sends load to a web application and shows the progress in a real-time terminal user interface. It is inspired by hey and written in Rust, built on the tokio runtime and the ratatui terminal UI library.

Optional features include building against native-tls instead of rustls, VSOCK support and experimental HTTP/3 support based on the H3 library. Pre-built binaries are available from the GitHub releases page, and oha can also be installed with cargo.

oha is distributed under the MIT licence and is actively developed on GitHub; version 1.16.0 was released in August 2026.
