About Speakeasy

Speakeasy began as an API platform that generates developer artifacts from OpenAPI specifications: idiomatic, type-safe SDKs, Terraform providers, a command line interface for an API and documentation that AI agents can understand. These tools help API owners offer polished client libraries without writing them by hand.

The vendor's homepage now leads with an AI control plane that finds, secures and governs AI agents, MCP servers and AI applications across an enterprise. It lists agent identity for permissioned actions, agent security to detect shadow AI and risky behavior, an MCP gateway with a central catalog of MCPs and skills, and agent monitoring for adoption, cost and activity. Speakeasy is proprietary and vendor-hosted, with documentation, a changelog, demos and a pricing page. Its audiences include security, compliance and AI enablement teams as well as API developers.
