ATAC

ATAC is an offline terminal API client that combines a full-screen TUI with subcommands for saved-request and one-shot API work. It covers HTTP and WebSocket requests, local environments, and imported collections without tying data to a hosted account.

• Create local JSON or YAML API collections and environment files, then edit or inspect saved requests from the shell or TUI.
• Send one-shot or saved HTTP and WebSocket requests with params, headers, auth, bodies, scripts, and response inspection.
• Import Postman, cURL, or OpenAPI inputs and export saved requests as cURL, raw HTTP, PHP Guzzle, Axios, or Reqwest snippets.

• Useful when an agent needs an offline API workspace with explicit commands for collections, requests, environments, and ad hoc try requests.
• Automation fit is limited by human-formatted stdout and the lack of --json, so follow-up parsing is brittle compared with API CLIs that emit structured results.
• Best for interactive API exploration or local request libraries that an agent can drive; less ideal for unattended pipelines or machine-first response processing.

• The product's center of gravity is still the fullscreen TUI, and some workflows like WebSocket messaging become interactive loops after connection.
• Auth coverage is partial compared with Postman-style tools; README explicitly marks OAuth1 or OAuth2 and AWS auth as missing.
