## What it is
ATAC is a feature-full terminal-based API client similar to Postman, Insomnia, or Bruno, built in Rust with a TUI interface. It is free, account-less, and works fully offline.

## Use cases
- send http requests from the terminal
- test rest apis without leaving the command line
- postman alternative that runs in a tui
- manage api request collections offline
- debug api endpoints without a gui
- use an api client with vim keybindings

## When to choose
- you live in the terminal and want a Postman-like tool
- you need an offline, account-free API client
- you prefer lightweight native tools over Electron apps
- you want vim-style keybindings for API testing

## When to avoid
- you need team collaboration or cloud-synced collections
- you prefer a graphical interface
- you need advanced features like automated API test suites or mocking servers
