🚀 Blast: A powerful, lightweight HTTP load generator for stress testing and benchmarking web applications with ease.

✨ Features

• High-Performance Load Testing: Send a specified number of requests at customizable concurrency levels to simulate real-world traffic and measure server response.

• HTTP/2 Support: Fully compatible with HTTP/2, allowing for efficient, high-throughput testing on modern web servers.

• Flexible Rate Limiting: Control request rate per worker (QPS) for fine-grained load management.

• Duration-Based Testing: Specify a duration to run tests continuously, ideal for long-term stress tests without counting requests.

• Multiple HTTP Methods: Supports a variety of HTTP methods including GET, POST, PUT, DELETE, HEAD, and OPTIONS.

• Customizable Headers: Add multiple custom headers for testing with different request configurations.

• Detailed Output Options: Choose between summary output or CSV format for detailed, structured response metrics.

• Timeout Control: Configure request timeouts to handle slow or unresponsive servers.

• Request Body Support: Send custom request bodies from text or file, supporting various payloads for POST/PUT tests.

• Compression and Keep-Alive Control: Optionally disable compression and keep-alive to test under different connection settings.

• HTTP Redirect Handling: Enable or disable following of HTTP redirects as needed.

• Proxy Support: Route requests through an HTTP proxy for testing in specific network setups.

• CPU Core Utilization Control: Specify the number of CPU cores for optimal load distribution based on your machine’s capabilities.

💡 Usage

blast runs a specified number of requests at a given concurrency level, providing comprehensive performance stats. Supports HTTP/2.

Usage: blast [options...] <url>

Options:
  -n  Number of requests to send (default: 200).
  -c  Concurrent workers (default: 50).
  -q  Rate limit per worker in QPS.
  -z  Duration of request sending (overrides -n). Ex: -z 10s, -z 3m.
  -o  Output format (default: summary; options: csv).

  -m  HTTP method (GET, POST, PUT, DELETE, etc.).
  -H  Custom headers. Repeatable, e.g., -H "Content-Type: application/json".
  -t  Request timeout in seconds (default: 20).
  -A  HTTP Accept header.
  -d  Request body.
  -D  Request body from file (e.g., ./file.txt).
  -T  Content-Type header (default: "text/html").
  -a  Basic auth in username:password format.
  -x  Proxy address as host:port.
  -h2 Enable HTTP/2.

  -host               HTTP Host header.
  -disable-compression  Disable response compression.
  -disable-keepalive    Disable TCP keep-alive for requests.
  -disable-redirects    Prevents following HTTP redirects.
  -cpus               Number of CPU cores to use (default: machine max).
