What is it?

Posting is a keyboard-centric API client that runs as a TUI, so it can be used over SSH as well as locally. It covers the same ground as graphical clients like Postman and Insomnia: building and sending HTTP requests, organizing them into collections, and inspecting responses.

Requests are stored locally as simple YAML files that are easy to read and keep under version control. Environments and variables are layered, and the tool supports HTTP, GraphQL, gRPC (including streaming) and server-sent events. Responses can be searched, viewed as a collapsible JSON tree, and filtered with JSONPath.

Posting can import curl commands, OpenAPI, Postman and Bruno collections, and export requests back to curl. It ships with 37 built-in themes and supports custom keybindings and user-defined themes.
