AFTER YOU INSTALL

One file. Your whole API workflow.

  1. Open your spec

    Start with an existing OpenAPI YAML or JSON file, or create a new API. Your local file remains the source of truth.

    Start with the editor

  2. Make your first request

    Choose an endpoint, set its environment and authentication, then inspect the response in Debug & Test.

    Read the debugging guide

  3. Bring AI into the workflow

    Connect your own model provider, or use hosted AI credits. Design and refine APIs through chat.

    Configure an AI model

Before you get started

Do I need to sign in?

You can start local work in the desktop app without a Cloud account. Sign in when you need Cloud hosting, purchases or hosted AI credits.

What am I downloading, and what is paid?

This page downloads the desktop app. Its perpetual license, optional Cloud hosting and hosted AI credits are separate products. Choose only what your workflow needs.

Where do my files and AI requests go?

Your spec is a local file. API debugging sends requests to the endpoints you configure. AI features send relevant context to the model provider you choose; Cloud publishing is a separate action.
