speakeasy

Speakeasy is an OpenAPI-native toolchain that automates the generation of polished, type-safe SDKs across 10+ programming languages including TypeScript, Python, and Go. It eliminates manual SDK maintenance by generating client libraries directly from OpenAPI specifications, ensuring consistency and reducing development time. Beyond SDKs, Speakeasy generates Terraform providers and contract tests, streamlining the entire API development lifecycle. The platform is trusted by companies like Mistral, Vercel, Clerk, and OpenRouter to maintain high-quality, production-ready SDKs.

["1. Prepare your OpenAPI specification file. Ensure it is complete and up-to-date with your API's current functionality.","2. Use the Speakeasy CLI to generate the SDK. Run the command: `speakeasy generate sdk --spec [SPEC_URL] --lang typescript`.","3. Review the generated SDK. Check the documentation and example usage to ensure it meets your needs.","4. Integrate the SDK into your development workflow. Use it to build and test your API clients.","5. For advanced users, generate a Terraform provider using the command: `speakeasy generate terraform --spec [SPEC_URL]`. This will enable infrastructure-as-code management of your API resources."]
