A Modern OpenAPI Native Toolchain

Polished and type-safe SDKs, Terraform providers and Contract Tests for your API. 10 Languages and counting.

How it works

Features

• SDK code that looks like you wrote it. Optimised for performance, debuggability and modern idiomatics.
• Complete Terraform Providers built on a Type-safe Go SDK.
• Contract Test generation with a pre built mock-server (Powered by Arazzo)
• Generate clean code-samples for syncing with API docs.
• Make npm install your-api. Manage versioning and publishing to package managers
• Modern OpenAPI 3.X toolchain for linting, cleaning, diff-ing and editing specs. (Powered by Overlays)
