hurley

A curl-like HTTP client with performance testing capabilities, written in Rust.

Features

• HTTP Methods: GET, POST, PUT, DELETE, PATCH, HEAD
• Custom Headers: -H "Content-Type: application/json"
• Request Body: Inline (-d) or from file (-f)
• Follow Redirects: -L
• Verbose Output: -v
• Performance Testing: Concurrent requests with latency metrics

Installation

cargo install hurley

Or build from source:

git clone https://github.com/dursunkoc/hurley.git
cd hurley
cargo build --release

Usage

Basic HTTP Requests

# Simple GET request
hurley https://httpbin.org/get

# POST with JSON body
hurley -X POST https://httpbin.org/post \
  -H "Content-Type: application/json" \
  -d '{"name": "test", "value": 123}'

# Include response headers
hurley -i https://httpbin.org/get

# Verbose output
hurley -v https://httpbin.org/get

# Follow redirects
hurley -L https://httpbin.org/redirect/3

Performance Testing

# 100 requests with 10 concurrent connections
hurley https://httpbin.org/get -c 10 -n 100

# Performance test with dataset
hurley https://httpbin.org --perf requests.json -c 20 -n 500

# JSON output for programmatic use
hurley https://httpbin.org/get -c 5 -n 50 --output json

Dataset Format

Create a JSON file with request definitions:

[
  {"method": "GET", "path": "/users"},
  {"method": "POST", "path": "/users", "body": {"name": "test"}},
  {"method": "GET", "path": "/users/1", "headers": {"Authorization": "Bearer token"}}
]

Performance Metrics

The performance test output includes:

• Request Summary: Total, successful, failed requests
• Timing: Total duration, requests/second
• Latency Distribution: Min, max, avg, p50, p95, p99
