About ATAC

ATAC, short for Arguably a Terminal API Client, brings a Postman-like layout to the terminal. You organise requests into collections, set headers, query parameters, bodies and authentication, use environment files and variables, run pre- and post-request scripts, and view responses, all with keyboard shortcuts and optional Vim-style key bindings. It can import Postman collections, OpenAPI files and curl commands, and stores collections as JSON or YAML files that work offline and can be committed to Git. It is written in Rust, ships as a single binary for Linux, macOS and Windows, and is free under the MIT licence. There is also a command-line mode for scripting requests. The trade-offs are that it is a young volunteer project with fewer features than desktop clients, and terminal interfaces suit some people more than others. It suits developers who want a fast, offline, Postman-style client in a terminal window.

Best for: Terminal users who want a Postman-style layout without a GUI app.
