CheckProxy is a modern, fast, and efficient command-line tool for checking the validity of HTTP proxy servers. It's built with .NET 6 and leverages asynchronous operations to check proxies concurrently, providing clear and concise results.

• High Performance: Built with async operations to test a large number of proxies very quickly.
• Concurrent Checks: Uses a semaphore to control the level of parallelism, preventing system overload.
• Flexible Input: Test a single proxy or a list of proxies from a file.
• Configurable Timeout: Set a custom timeout for all checks.
• Clear Output: Uses Spectre.Console to display results in a clean, color-coded table.

To use CheckProxy, you can either download a pre-built executable from the Releases page (TBD) or build it from source.

1. Clone the repository:

   git clone https://github.com/your-username/checkproxy.git
   cd checkproxy

2. Build the project: You will need the .NET 6 SDK installed.

   dotnet build -c Release

3. Run the application: After building, you can find the executable in the bin/Release/net6.0 directory.

   ./bin/Release/net6.0/CheckProxy --help

CheckProxy 192.168.1.100:8080

Provide a text file with one proxy per line.

CheckProxy --file proxies.txt

You can specify a timeout in milliseconds for the checks. The default is 5000ms.

CheckProxy --file proxies.txt --timeout 10000

For a full list of commands and options, run:

CheckProxy --help
