Goa is a design-first framework for building APIs and microservices in Go. You define your API in a Go-based DSL and it generates server code, type-safe clients, and OpenAPI documentation for HTTP, gRPC, and WebSocket transports, with a Goa-AI extension for building agentic systems with MCP tool integration.

Use cases

• generate go api server and client code from a design
• build rest and grpc microservices in go without boilerplate
• keep openapi docs in sync with code
• define api validation rules once and enforce them
• build ai agents with typed tools in go
• integrate mcp tool servers into go agents

When to choose

• you want design-first API development with zero drift between code and docs
• you need both HTTP and gRPC transports from a single design
• you want auto-generated OpenAPI specs and type-safe clients
• you're building agentic systems in Go with typed tool contracts

When to avoid

• you prefer writing handlers directly without code generation
• you're building a simple one-off HTTP service where a DSL adds overhead
• your stack isn't Go
