One toolkit for every API contract
API Genie lints and formats your API descriptions, catches breaking changes before they ship, mocks and contract-tests live APIs, generates clients, servers and documentation for the stack you already use, and edits the files in forms without losing a byte. From the command line, your browser, the desktop or VS Code, by you or by an AI agent.
brew install mykulyak/apigenie/apigenie
apigenie diff rates every change between two versions of an API and fails the build on the breaking ones.
Generates code for
- TypeScript
- Python
- C#
- Java
- Go
- Elixir
From the first lint to the published docs
Stop stitching together a linter, a diff tool and a handful of code generators. API Genie covers the whole workflow.
Lint and format
Check every API description against your rules and put it in one style
Catch breaking changes
Know what every change does to your clients before it ships
Generate code
Clients, servers, schemas and test data in six languages
Mock and test
Mock APIs from their contracts, and check real ones against them
Publish API docs
Reference pages and documentation sites from the contract
Edit visually
Edit OpenAPI and AsyncAPI in forms, and keep your files
Catalog your APIs
Know every API of a repository and who owns it
Work with AI agents
Checks, diffs and machine-readable reports for the agents that write your APIs
Works with your API standards
OpenAPI 3.0 to 3.2, Swagger 2.0, AsyncAPI, Protobuf and GraphQL
Start with one file and one command
Install the CLI and lint the API description you have. The diff, the mock server, the generators and the docs read the same file, when you want them.
