What is Speakeasy?
A developer platform that auto-generates type-safe, production-ready SDKs in multiple languages (TypeScript, Python, Go, Java, C#, PHP, Ruby) from an OpenAPI spec. It also generates MCP servers, Terraform providers, and CLIs, and in 2026 has expanded into an "AI control plane" for discovering, securing, and governing AI agents and MCP servers across the enterprise.

About "Speakeasy"
What is Speakeasy
Speakeasy is a developer platform that auto-generates type-safe, production-ready client SDKs in multiple languages from an OpenAPI spec. Beyond SDKs, it also generates MCP servers, Terraform providers, and CLIs, automating the work of distributing your API in a form that's easy to consume. In 2026 it has broadened its positioning further into an "AI control plane" for discovering, securing, and governing AI agents and MCP servers across the enterprise.
Speakeasy's core is "auto-generating usable artifacts from OpenAPI." It generates type-safe SDKs in major languages like TypeScript, Python, Go, Java, C#, PHP, and Ruby, and can also output MCP servers, Terraform providers, and CLIs. Building on that, it now foregrounds an enterprise "AI control plane" that catalogs internal AI agents / MCP servers / Skills and governs them with IdP-based access control, auditing, and observability.
How to use
Provide a spec, generate, and publish.
Provide a spec
Import your OpenAPI spec (schema) into Speakeasy.
Generate
Generate type-safe SDKs, plus MCP servers, Terraform, and CLIs.
Publish and automate
Regenerate via CI/CD and distribute as per-language packages.
Govern
Discover, secure, and govern agents/MCP with the AI control plane.
SDKs and MCP servers are generated from OpenAPI, and once wired into CI/CD, they regenerate automatically on every spec change. The enterprise AI control plane manages permissions via IdP (SAML/OIDC) and provides audit logs and observability.
Key features
01Multi-language, type-safe SDK generation
Auto-generates type-safe client SDKs in major languages like TypeScript, Python, Go, Java, C#, PHP, and Ruby from an OpenAPI spec (Rust and C++ coming soon). Easier to maintain than hand-writing, with end-to-end CI/CD regeneration and package publishing.
02MCP server, Terraform, and CLI generation
From the same OpenAPI spec, it can also generate remote/local MCP servers, Terraform providers, and CLIs (Alpha). This lets you distribute your API in a form that's easy for AI agents and infrastructure management to consume.
03AI control plane
Puts internal AI agents / MCP servers / Skills into one catalog and controls access by team and role via your existing IdP (SAML/OIDC, SSO). It offers inspection of prompts/responses/tool calls, PII and credential blocking, audit logs, tracing, and alerts, and complies with SOC 2 Type II, ISO 27001, and more.
Pricing
Pricing is a custom enterprise quote (Enterprise).
The official pricing page shows only an Enterprise plan ("Tailored," contact sales), with no public prices or free tier stated (usage is metered by "requests" and "tools," but unit rates are not disclosed). Standalone SDK-generation pricing could not be confirmed on the current official site. Check the official pricing page for the latest (as of August 2026).
How it differs from other SDK-generation/API tools
Speakeasy's strength is that it auto-generates everything from type-safe SDKs to MCP servers from OpenAPI, and can even handle governance of AI agents in one flow. Compared with hand-written SDKs or general-purpose code generation, it reaches into production-quality artifacts and operational governance.
| Aspect | Speakeasy | Hand-written SDKs | General code generation |
|---|---|---|---|
| Generation | Type-safe, multi-language, auto-regenerated | Per-language by hand | Inconsistent quality |
| Scope | SDK + MCP/Terraform/CLI + AI governance | SDK only | Fragmentary |
| Maintenance | Follows spec changes via CI/CD | Manual updates | Manual |
Hand-written SDK maintenance and general-purpose code generation are the comparison points. For enterprises that want to distribute their API as production-quality multi-language SDKs and MCP servers — and also govern internal AI use — Speakeasy is a strong choice.
