About:
Atac is a terminal-based API client designed for developers who prefer working in the command line. It provides a Postman-like interface for crafting, sending, and managing HTTP requests directly from the terminal. The tool emphasizes keyboard-driven navigation and efficiency, making it ideal for rapid API testing and development workflows.
Key Features:
  • Terminal User Interface (TUI) for intuitive navigation
  • Support for various HTTP methods (GET, POST, PUT, DELETE, etc.)
  • Request composition with headers, body, and query parameters
  • Environment variable management for different configurations
Use Cases:
  • Testing REST APIs during backend development
  • Automating API requests in CI/CD pipelines
  • Quickly inspecting API responses on remote servers
Alternatives:
  • Postman – GUI-based vs Atac's terminal-native interface
  • curl – Atac provides a persistent, interactive session vs curl's single-shot commands
  • httpie – Both are CLI-focused, but Atac offers a full TUI experience
