Scoold

Scoold by Erudika is a robust and flexible open-source Q&A platform inspired by Stack Overflow. It offers a full-featured Q&A experience where users can ask and answer questions, upvote/downvote posts, earn reputation points and badges. Scoold supports geolocation-based filtering of questions, full-text search, distributed caching, and integrations with Slack, Mattermost, and Microsoft Teams. It allows for extensive customization, including custom theming, badges, and authentication providers. Scoold is optimized for cloud deployment and can be self-hosted or deployed on services like Heroku. The platform prioritizes simplicity with a lightweight jQuery frontend, server-rendered pages for SEO, and a clean, responsive design powered by Materialize CSS. Scoold Pro, the paid version, adds premium features like SAML authentication, file uploads, advanced syntax highlighting, unlimited spaces, and multiple admins.
