Uffizzi is an open-source engine for creating lightweight, ephemeral preview environments for APIs and full-stack applications. Uffizzi is designed to integrate with any CI/CD system and enables teams to preview new features before merging and to mitigate the risk of introducing regressions into a codebase. Each preview gets a shareable URL that's updated when you push new commits or image tags, so teams can provide continual feedback during the iterative development process. Previews can be configured to expire at a set time or be destroyed when a pull request is closed, so environments exist only as long as they are needed. Uffizzi helps to parallelize new feature efforts by overcoming the bottleneck of shared development environments.
