About Posting

Posting is an API client built as a terminal user interface, so you get something close to a desktop app without leaving the command line, even over SSH. You can build HTTP, GraphQL and gRPC requests, edit headers, bodies and authentication in panes, inspect formatted responses, use environments and variables, run Python scripts before and after requests, and jump around with a command palette and keyboard shortcuts. Collections are stored as simple YAML files, so they live in Git alongside your code, and you can import from Postman, OpenAPI and curl commands. It is written in Python with the Textual framework, has many colour themes, and is free under the Apache 2.0 licence. It runs on Linux, macOS and Windows terminals. The trade-offs are that terminal interfaces have a learning curve, team collaboration means sharing files yourself, and some features are still in beta. It suits keyboard-driven developers who live in the terminal.

Best for: Keyboard-driven developers who want a full API client in the terminal.
