Load-test an HTTP endpoint with a fast reproducible CLI probe using oha

Run a quick concurrent HTTP benchmark against a URL before deeper performance work or regression triage.

Prerequisites

oha

Installation

Use the upstream install or setup path that matches your environment:

• cargo install oha
• cargo install --no-default-features --features native-tls oha
• cargo install --features vsock oha
• brew install oha

Requirements and caveats from upstream:

• This program is built on stable Rust, with both make and cmake prerequisites to install via cargo.
• It will remain experimental as long as H3 is experimental. It currently depends on using rustls for TLS.

• Official Docker image

Basic usage or getting-started notes:

• 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.
