Speakeasy
OpenAPI-to-SDK, Terraform and MCP generator, now an AI control plane
Speakeasy is a aPI & developer docs tool for Developers and Enterprise, offered as paid. Founded in United States in 2022.
About Speakeasy
Speakeasy is a San Francisco developer tools company founded in 2022 by Sagar Batchu and Simon Yu. It raised a $15 million Series A led by FPV Ventures in October 2024, with GV and Quiet Capital participating. Its original core job is to take an OpenAPI spec and generate idiomatic, type-safe SDKs, Terraform providers and CLIs that API companies can publish and keep in sync as the API changes.
SDK generation covers TypeScript, Python, Go, Java, C#, PHP and Ruby, with Rust and C++ coming soon. Generated code handles pagination, retries, authentication and webhooks, and a GitHub workflow regenerates and publishes packages to npm, PyPI and other registries on every spec change. In September 2025 Speakeasy launched Gram to turn APIs into hosted MCP servers, and in 2026 it repositioned around an AI control plane: agent identity synced from Okta or Entra, agent security, an MCP gateway and agent observability. Pricing is quote-based; the pricing page lists only a tailored Enterprise plan.
Speakeasy fits API-first companies that want high-quality SDKs in several languages without a dedicated SDK team, and enterprises governing how agents reach internal tools. It is not a docs portal on its own and lacks public self-serve pricing. Fern is its closest rival for SDK plus docs generation, while ReadMe and Mintlify focus on developer documentation.
Recent development: on October 13, 2026 Speakeasy announced a Tailscale partnership that lets Enterprise customers run its MCP gateway on a private tailnet. Ask sales whether SDK-only use is priced separately from the AI control plane.

Best for
API-first companies that need idiomatic multi-language SDKs and Terraform providers, and enterprises governing AI agent access to tools.
Not ideal for
Teams looking mainly for a hosted API docs portal or transparent self-serve pricing (Fern, ReadMe, Mintlify).

Our take
Speakeasy produces some of the best generated SDKs available and is now one of the more complete MCP governance platforms. Shortlist it against Fern for SDKs and get a quote early, since there is no public price list.
