Azure DevOps Pipelines (https://azure.microsoft.com/en-us/services/devops/pipelines/) is a hosted PaaS (short for Platform as a Service) solution for CI/CD from Microsoft. It is free for public/OSS projects and needs a subscription for use by private/enterprise projects. It is integrated well with GitHub and provides a nice intuitive GUI to work with. It supports applications written in a variety of languages and platforms and is heavily used by open source projects, including JHipster, for their CI needs. It is very easy to set up and use and has a simple YAML-based configuration. Advanced setups are typically done using shell scripts that can be triggered by the YAML configuration using hooks.
