The Homebrew formula installs the `openapi` command. ### Project history The repository was created on August 22, 2024. Speakeasy describes it as the OpenAPI library used directly in its products, including SDK generation and Gram, and a January 2026 engineering post introduced it as a comprehensive Go package set for OpenAPI, Swagger, Arazzo, and Overlay specification documents. The project combines several document families under one command: OpenAPI 3.0, 3.1, and 3.2 support; Swagger 2.0 reading and upgrading; Arazzo workflow documents; and OpenAPI Overlays. That scope reflects newer OpenAPI Initiative work around workflows and overlays, not just classic endpoint descriptions. ### Adoption history The package is young compared with OpenAPI Generator, but it has first-party adoption inside Speakeasy's product stack and is distributed as a Go module, GitHub releases, install scripts, and a Homebrew formula. The README and install guide also document direct `go install` usage for developers who want the CLI from source. ### How it is used The CLI groups commands under `openapi spec`, `openapi swagger`, `openapi arazzo`, and `openapi overlay`. Users validate, lint, bundle, inline, join, clean, optimize, sanitize, snip, upgrade, query, explore, apply overlays, compare specs to generate overlays, and validate Arazzo workflows. Go developers use the packages programmatically for reading, creating, mutating, walking, validating, upgrading, linting, and overlay operations. The linter subpackage includes built-in rules for style, security, and semantic validation, with custom rules written in TypeScript or JavaScript. ### Why package nerds care The package is interesting because the `openapi` formula name maps to one vendor-maintained implementation rather than the OpenAPI standard itself. It is also a compact example of newer API-description tooling where specs, workflow descriptions, overlays, lints, and query operations are bundled into a single CLI. ### Timeline - August 22, 2024: the GitHub repository was created.
