About ATAC

ATAC is a Postman-style API client that runs entirely in the terminal, written in Rust. It manages collections and requests stored in your own readable JSON or YAML files, supports HTTP, WebSocket and MQTT, offers pre- and post-request scripting, and imports Postman collections, OpenAPI specs and cURL commands without requiring an account.
