What is Speakeasy SDK?

Speakeasy SDK is a developer platform that automates the creation and maintenance of SDKs, Terraform Providers, and MCP (Multi-Cloud Provisioning) servers directly from OpenAPI specifications. It targets API product teams, platform engineers, and developer experience teams looking to streamline their API integration and provisioning processes. The platform ensures that generated SDKs are idiomatic, type-safe, and production-ready across multiple programming languages, handling complex features like OAuth 2.0, retries, and pagination. For Terraform, it transforms OpenAPI specs into fully functional providers that integrate seamlessly with Infrastructure as Code (IaC) workflows, reducing manual effort and ensuring consistency. Additionally, Speakeasy supports the generation and deployment of MCP servers, enabling AI experiences by powering agents with first and third-party API access.
