At Humanitec, they've made their API available as a public Beta to provide teams with more opportunities for automation and integration, building on the functionality of their existing UI. The API offers features such as spinning up environments, automating deployments, and checking out running configurations, allowing developers to integrate new tech like DNS, databases, and message queues. By publishing the API as Beta, Humanitec aims to gather feedback from the developer community on ease-of-use and documentation quality, while keeping their cutting-edge UI in development to ensure feature parity with the API.
