Building a GraphQL Explorer CLI — Query Any API from Your Terminal

Building a GraphQL Explorer CLI — Query Any API from Your Terminal Testing GraphQL APIs shouldn't require firing up a browser. GraphQL Playground, Insomnia, and Altair are excellent tools, but they pull you out of your terminal workflow. If you're already SSH'd into a server, running a CI pipeline, or simply prefer the command line, you need something faster. In this tutorial, we'll build gql-explorer , a Node.js CLI that introspects any GraphQL endpoint, lets you explore schemas interactively, run queries with autocomplete, manage authentication headers, and bookmark your favorite queries — all without leaving the terminal. The Problem with Browser-Based GraphQL Tools Every GraphQL developer knows the dance: write code in your editor, switch to Playground to test a query, copy the result back, tweak the query, switch again. Browser-based tools are powerful but introduce context switching that breaks flow. There are deeper issues too. Browser tools don't integrate with shell pipelines.
