Scoold is an open source Q&A platform written in Java. It supports most of the features found in Stack Overflow and adds a few extras like spaces, single sign-on and geotagging of questions. Scoold is lightweight - the backend is completely separated and handled by Para. It can be deployed on AWS or on premise.

Para is a general-purpose backend server for the cloud. It handles read and write operations for Scoold and keeps it easy to maintain. A self-hosted or a managed Para server is required for Scoold to work properly. For more information about Para, visit https://paraio.org
