# 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](https://github.com/sfackler/rust-native-tls) instead of [rustls](https://github.com/rustls/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](https://github.com/hyperium/h3) library by the developers of Hyper.
