Posting
What Posting is
Posting is a free, open-source terminal application for developing and testing APIs on Linux, macOS, and Windows desktops. Its keyboard-centric interface includes navigation, a command palette, request autocompletion, and customizable keybindings. Requests are stored locally in readable YAML collections that can be checked into version control. Variables from one or more .env files can be substituted into requests, and Python setup, pre-request, and post-response scripts can prepare requests or process responses. Posting offers experimental imports from curl, OpenAPI 3.x, and Postman collections, plus cURL export. Request bodies can open in configured external editors, while responses can be viewed in external pagers, including a JSON-focused pager. The maker says it can run locally, over SSH on remote machines and containers, and on Raspberry Pi. Installation guidance recommends uv or pipx; Homebrew installation is unsupported. Posting does not provide WebSocket support or automated test runs.
