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.
