What is Speakeasy API?
Speakeasy API is a platform that automates the generation of developer tools from your OpenAPI specification. It allows developers to quickly create idiomatic, type-safe SDKs in multiple programming languages, eliminating the need for manual SDK creation and maintenance. This ensures consistency, reduces integration time, and keeps SDKs up-to-date with API changes through CI/CD integration.
Beyond SDKs, Speakeasy also specializes in generating Terraform Providers directly from OpenAPI specs. This enables seamless integration of APIs into Infrastructure as Code (IaC) workflows, allowing developers to provision APIs without additional tooling. The platform aims to remove the burden of manual provider development, ensuring providers are always in sync with the API and offering comprehensive documentation.
The product is designed for API product teams, platform engineers, DevEx teams, and Infra/Ops leads who want to improve developer experience, accelerate release schedules, and standardize API consumption. By automating these critical development assets, Speakeasy helps teams build with confidence and ship faster, providing immediate ROI through improved developer experience and reduced maintenance overhead.
