Show HN: Ghostman – A fast, keyboard-driven TUI API client and webhook inspector

Ghostman is a Python terminal application for sending API requests and inspecting webhooks, aimed at developers who prefer keyboard-driven tools and local workflows. It presents itself as a lightweight alternative to larger API clients, avoiding cloud accounts and keeping request collections on the user’s machine. The interface supports keyboard navigation, including Vim-style workflows, and displays HTTP status, response size, timing information, and formatted, colorized JSON. It supports GET, POST, PUT, DELETE, and PATCH requests with custom headers and raw JSON bodies.

A built-in webhook receiver can be toggled with Ctrl+W and listens on 127.0.0.1:9090, capturing incoming callbacks for live inspection without a separate tunnel service. Requests are organized into collections stored as readable YAML in a project’s .ghostman directory, so they can be version-controlled and shared with a team. Users can send a request with Ctrl+S, move between interface fields with Tab, and quit with Ctrl+Q. The project requires Python 3.10 or later and is distributed under the MIT license. Its roadmap includes replaying captured webhooks as outbound requests, environment-variable support, cURL export, and a standalone binary, indicating that some planned capabilities are distinct from the currently described core functions.
