    Use Cases & Benefits

    • Generates HTTP load with real-time terminal UI to benchmark web applications using Rust and Tokio.
    • Offers advanced features like HTTP/2 and experimental HTTP/3 support with customizable request rates and latency correction.
    • Use for stress testing web servers with controlled query per second and concurrency settings to simulate realistic traffic.
    • Use for benchmarking HTTP/2-enabled services with parallel request capabilities and detailed latency statistics.
    • Use for generating dynamic URLs from regex patterns or URL files to simulate diverse and realistic load scenarios.

    From the README

    oha is a tiny program that sends some load to a web application and show realtime tui inspired by rakyll/hey.

    This program is written in Rust and powered by tokio and beautiful tui by ratatui.

    This program is built on stable Rust, with both make and cmake prerequisites to install via cargo.

    You can optionally build oha against native-tls instead of rustls.

    You can enable VSOCK support by enabling vsock feature.

    You can enable experimental HTTP3 support by enabling the http3 feature. This uses the H3 library by the developers of Hyper. It will remain experimental as long as H3 is experimental. It currently depends on using rustls for TLS.

    You can download pre-built binary from Release page for each version and from Publish workflow and Publish PGO workflow for each commit.
