## What it is
Altair is a feature-rich GraphQL client IDE for running queries, mutations, and subscriptions, with schema documentation, environments, file uploads, and a plugin system. It ships as desktop apps, browser extensions, a web app, and an embeddable express middleware.

## Use cases
- test and debug graphql queries and mutations
- run graphql subscriptions locally
- explore and search a graphql schema
- manage graphql query collections to share with a team
- embed a graphql playground in an express server
- switch between local, staging, and production graphql environments

## When to choose
- you want a full-featured GraphQL IDE across desktop, browser, and web
- you need subscriptions, file uploads, pre-request scripts, and environments
- you want to embed a GraphQL client UI into your own app via middleware

## When to avoid
- you only need quick ad-hoc REST requests (use Postman/Insomnia instead)
- you want a minimal lightweight GraphQL playground with no extra features
- you need a CLI-only or automated testing workflow
