Speakeasy

Speakeasy is a developer platform that automates the creation of essential API tooling from OpenAPI specifications. It generates type-safe SDKs in multiple programming languages, builds command-line interfaces, creates Terraform providers, and constructs MCP (Model Context Protocol) servers. This allows development teams to quickly provide consistent, high-quality developer experiences around their APIs without manual coding.

The platform works by analyzing your OpenAPI definition and automatically producing idiomatic code in languages like TypeScript, Python, Go, and Java. It handles authentication, error handling, and documentation while maintaining type safety. For AI development, Speakeasy creates MCP servers that enable coding assistants to interact with your API directly from their development environment.

Software engineers at companies building APIs benefit most from Speakeasy, particularly those working on developer platforms or AI-native applications. Teams use it to accelerate SDK development, ensure consistency across client libraries, and enable AI agents to work with their APIs through standardized MCP interfaces. The platform helps maintain quality while reducing the maintenance burden of manually generated code.
