The Homebrew package installs the `openapi-generator` CLI. ### Project history The repository was created on May 12, 2018 as a fork of Swagger Codegen. The project history in the README says more than 40 Swagger Codegen contributors and template creators forked the project because of disagreement around the Swagger Codegen 3.0.0 beta and project direction, choosing to maintain a community-driven generator under the OpenAPI Generator name. The migration guide describes OpenAPI Generator as a fork of `swagger-codegen` between versions 2.3.1 and 2.4.0 and documents practical migration changes: new Maven coordinates, Docker images, generator names, parameter names, template-variable changes, and `.openapi-generator-ignore` replacing `.swagger-codegen-ignore`. ### Adoption history OpenAPI Generator became one of the central tools in the OpenAPI ecosystem because it covers many generated targets rather than one language. Its README lists client generators, server stubs, documentation generators, schema generators, and auxiliary outputs such as Postman collections, Protocol Buffers, GraphQL schemas, and database schemas. Distribution grew around the different places API generation happens: Maven Central artifacts for Java builds, Maven and Gradle plugins, Docker images, an npm CLI wrapper, pip packaging, direct JAR downloads, launcher scripts, Homebrew, and other package managers. The project also has a sponsorship and backer structure, reflecting its role as shared infrastructure for many companies and API teams. ### How it is used The common workflow is to run `openapi-generator generate` with an input OpenAPI document and a selected generator name. Teams use it to produce SDKs, server skeletons, docs, tests, schemas, and config from a spec that can be versioned with the API. The CLI also includes discovery and support commands such as `list`, `config-help`, `author`, and `batch`. Build integrations let organizations generate code during Maven, Gradle, Docker, npm, or CI jobs instead of treating generated clients as hand-maintained source. ### Why package nerds care OpenAPI Generator is a package-manager stress test: one upstream project surfaces as a Java artifact, CLI JAR, Docker image, npm package, pip package, Homebrew formula, plugins, and generated packages in many target languages. It is a single tool whose output often becomes many other packages. Its fork history also matters. The project represents the OpenAPI ecosystem's shift from Swagger-branded tooling toward community-governed OpenAPI tooling after the OpenAPI Initiative standardized the former Swagger specification. ### Timeline - 2010: the OpenAPI Specification's lineage began with Swagger. November 5, 2015: the OpenAPI Initiative was announced under the Linux Foundation with SmartBear donating the Swagger specification. May 12, 2018: OpenAPI Generator's repository was created as a Swagger Codegen fork. June 8, 2026: GitHub releases list v7.23.0. ### Related projects - OpenAPI Generator is directly related to Swagger Codegen, the OpenAPI Specification, OpenAPITools, Maven and Gradle plugins, Docker images, npm and pip CLI wrappers, and other OpenAPI code generators. ### Sources - - - - - - - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** openapi-generator - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - pacman - openapi-generator - 7.23.0-1: normalized package name match | Arch Linux sync databases: openapi-generator from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Generation of API client libraries, server stubs, documentation and configuration | https://github.com/openapitools/openapi-generator/ ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [openjdk](https://www.automicvault.com/pkg/brew/openjdk/) - Runtime dependency declared by Homebrew. - [create-api](https://www.automicvault.com/pkg/brew/create-api/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, openapi. - [openapi-diff](https://www.automicvault.com/pkg/brew/openapi-diff/) - Shares av.db curated category or tags: api-development, cli, developer-tools, openapi. - [openapi-tui](https://www.automicvault.com/pkg/brew/openapi-tui/) - Shares av.db curated category or tags: api-development, cli, developer-tools, openapi. - [swagger-codegen](https://www.automicvault.com/pkg/brew/swagger-codegen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, openapi. - [tfplugingen-openapi](https://www.automicvault.com/pkg/brew/tfplugingen-openapi/) - Shares av.db curated category or tags: cli, code-generation, developer-tools, openapi. - [autogen](https://www.automicvault.com/pkg/brew/autogen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [configen](https://www.automicvault.com/pkg/brew/configen/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. - [counterfeiter](https://www.automicvault.com/pkg/brew/counterfeiter/) - Shares av.db curated category or tags: cli, code-generation, developer-tools. ## Combined YAML source View the package source record on GitHub.
