Zally is an API linter and quality assurance tool for OpenAPI specifications. It supports OpenAPI 3 and Swagger OpenAPI 2, with a RESTful API, command-line interface, and web interface. Its standard configuration checks APIs against Zalando’s RESTful Guidelines, and the project says it can also be used out of the box by others. Teams can enable or disable server-side rules, configure some existing rules, or implement their own in Kotlin. An API definition can use the x-zally-ignore extension to disable rules for that API. The web interface lists implemented rules and can lint external files and API definitions in its online editor. The project describes starting the web UI, server, and database together using Docker Compose. It also lists an unofficial Zally Maven Plugin integration. Maintained by Zalando, Zally is offered under an MIT license with an exception. Its Open source plan costs nothing.
