Create, collaborate, and prototype APIs with Stoplight Studio

Download For Mac, Windows, or Linux
Start designing your API in minutes. Use the OpenAPI Specification (formerly known as Swagger) with Stoplight Studio to design consistent and standardized HTTP APIs for your organization. Without writing any code, model complex APIs faster than ever while simultaneously getting feedback on your prototypes with our instant mock servers.

NEW Style Guide Projects

Quickly and easily add style guides directly into your Studio design from a list of approved Style Guides. You can also override rules in your project and skip style guides for certain APIs, endpoints, or models, providing more flexibility and control of your API design workflow. Now available in Pro and Enterprise plans.

A Powerful OpenAPI v2 & v3 Visual Editor

Design an API with speed and efficiency from scratch. Stoplight Studio decreases the learning curve so you don't need to be an OpenAPI expert to create first-class API designs. Describe endpoints, headers, bodies, multiple responses, query string parameters, shared models, and examples, and much more for complex APIs.

Instant Mock Servers

Instantly prototype and collaborate on your API design with our integrated, instant Mock Servers, powered by Prism. A mock API simulates the behavior of a real API allowing collaboration and feedback on your API design. Automatically update to match your API design. Mock a single API or multiple APIs at once.

Generate API Documentation with OpenAPI and Markdown

Create API documentation in minutes. Combine OpenAPI documents with Markdown to create robust, searchable, internal and external API documentation for your organization.

OpenAPI Linting and API Style Guides

Ask 100 API designers what makes a good API design and you'll get 101 answers, but all most developers really want is consistency. Using an API style guide, can reduce decision making and improve consistency for all your teams.

With built-in linting and API style guides, powered by Spectral, Stoplight Studio can improve the quality of your API. You can use the default style guide, extend it, or write one to match your organization's style guide (coming soon in Studio).

Collaborate Flexibly with Git Workflows

Collaborate on API designs easily using your existing Git repositories. Stoplight fits seamlessly into your current development workflows.
