Speakeasy

Speakeasy is a complete API toolchain that transforms your OpenAPI specification into ready-to-use developer tools. It creates native SDKs that follow best practices for each programming language, making them feel handwritten rather than machine-generated.

The platform includes three main products: SDK Generation for creating client libraries, Gram for building and hosting MCP servers that connect AI applications to your APIs, and interactive documentation that lets users test endpoints directly. Everything stays synchronized with your API changes through automated workflows.

Speakeasy goes beyond basic code generation by adding features like retry logic, error handling, pagination support, and OAuth integration. The generated code includes full type safety, detailed documentation, and works smoothly with popular development tools. Whether you are building internal tools or public APIs, Speakeasy helps ensure a consistent and professional developer experience.

Getting started with Speakeasy is straightforward. Here are the steps to generate your first SDK:

• Sign up for a free account at app.speakeasy.com. New accounts include a 14-day trial of business features.

• Install the Speakeasy CLI tool on your computer using npm, Homebrew, or direct download from their website.

• Run the command "speakeasy quickstart" in your terminal. The tool will guide you through the setup process.

• Provide your OpenAPI specification file when prompted. Speakeasy will validate the specification and show any issues that need fixing.

• Select which programming languages you want to generate SDKs for. You can choose multiple languages at once.

• Configure publishing options if you want to automatically publish SDKs to package managers like npm, PyPI, or Maven.

• Review the generated code using the web-based Studio interface, where you can customize names, add documentation, and adjust the structure.

• Set up GitHub Actions to automatically regenerate and publish SDKs whenever your API changes.
