Posting is an HTTP client, not unlike Postman and Insomnia. As a TUI application, it can be used over SSH and enables efficient keyboard-centric workflows. Your requests are stored locally in simple YAML files, meaning they're easy to read and version control. Some notable features include: "jump mode" navigation, environments/variables system with autocompletion, syntax highlighting powered by tree-sitter, Vim keys, various builtin themes, a configuration system, "open in $EDITOR", and a command palette for quickly accessing functionality.
