Introduction

Posting is an HTTP client that lives in your terminal. The README compares it to Postman and Insomnia, but as a text user interface (TUI) it can run over SSH and supports keyboard-centric workflows.

Requests are stored locally as simple YAML files, so they are easy to read and version control. Features include request tabs, layered environments and variables with autocompletion, header autocompletion, collection search, response search, a collapsible JSON tree with JSONPath filtering, and support for HTTP, GraphQL and gRPC.

The stable 2.x line is a Python application built with Textual; the README says Posting 3, currently in beta, is a single binary written in Go. The project has about 12,600 GitHub stars.

In the quality loop it supports manual API exploration, especially on remote servers.

The source code is at darrenburns/posting on GitHub under the Apache-2.0 licence, with about 12,600 stars; the most recent commit was on 15 October 2026.
