Installing a GUI Client

There are several free GUI tools available for interacting with GraphQL.

The steps that follow demonstrate accessing the API with a Altair as a Chrome browser extension, but the principles are the same for any other client.


Some users have reported problems when using the Altair extension for Chrome, and the Altair developer recommends using the desktop client whenever possible. If you experience problmes with the Chrome extension, consider using the desktop client instead.

To install the extension, go to and click the download button. At the time of this writing, the landing page looks as follows:
