SDKs
Generate handwritten SDKs
Turn your OpenAPI spec into production-ready, idiomatic SDKs across multiple languages. Built for internal and external APIs alike, every SDK is type-safe, customizable, and ready to drop into your existing workflow.
Automated SDKs your team will be proud of
Upload your OpenAPI spec and generate production-ready, type-safe SDKs in your team's preferred languages. Speakeasy's SDK Generator handles everything from OAuth 2.0 and custom logic to retries, pagination, and full documentation.
Pain points
Great APIs deserve better SDKs
Manual work doesn't scale
Hand-building and maintaining SDKs is time-consuming and error-prone
Generic doesn't cut it
Default generators miss the details that make SDKs feel native
Poor DevEx kills trust
When SDKs fall short, developer trust and velocity take the hit
SDK Generation
APIs change fast. Your SDKs should too.

Spec in. SDK out.

2
Customize without compromise
Use overlays and hooks to modify SDK functionality, structure, and behavior without altering the core generation process.
3
Ship with every commit
Incorporate SDK generation into your continuous integration and deployment workflows to ensure your SDKs are always up-to-date.
4
Publish with confidence
Easily publish your SDKs to popular package managers like npm, PyPI, Maven, and more, facilitating distribution and adoption.
