Ghostman

What is Ghostman?

Ghostman is a terminal-based API client and webhook inspector built in Python. It runs entirely on your local machine without requiring cloud accounts or external services. The application starts in approximately 150 milliseconds and uses around 30 megabytes of memory, making it significantly lighter than desktop alternatives that rely on web frameworks.

Users compose and send HTTP requests using full keyboard shortcuts instead of mouse navigation. The interface displays real-time performance metrics like DNS lookup time and total transfer time, alongside syntax-highlighted JSON responses. Requests and collections are saved as plain JSON or YAML files in a local directory, allowing easy version control with Git.

A built-in webhook server listens on port 9090, enabling developers to capture incoming HTTP callbacks directly from their terminal. The tool supports standard HTTP methods including GET, POST, PUT, DELETE, and PATCH. Installation is available through pip or by cloning the repository and running the main script.
