Getting Started

The Speakeasy CLI provides access to features of the Speakeasy Platform. This CLI supports an interactive mode. Simply type speakeasy in you terminal for a guided setup and usage experience.


In your terminal, run:

brew install speakeasy-api/homebrew-tap/speakeasy


Authenticate with the Speakeasy platform to use the Speakeasy CLI:

speakeasy auth login

A browser window will open. Log in to the Speakeasy Platform and create a workspace (or select a workspace if you have previously used the platform) by following the prompts.

When you are redirected to your workspace, Speakeasy will generate an API key for you. Return to the terminal, and you should see a message that you are authenticated.


When you have installed the Speakeasy CLI, get your OpenAPI spec and generate an SDK with a single command:

speakeasy generate sdk -s openapi.yaml -o ./sdks/go/ -l go

Getting started is that easy.

For the full set of CLI commands, type speakeasy -h.
