There is no doubt that Stack Overflow is the most popular resource for developers to get answers. However, some people may be looking for a self-hosted, open-source alternative for communities and developer teams. That's where Scoold comes in – let us introduce you to it.

What is Scoold?

Scoold is a Q&A and knowledge sharing platform designed specifically for teams. The project was initially created in 2008 and then released in 2012 as a social network for schools inspired by Stack Overflow. In 2017, it underwent a major refactoring, repackaging and was made open-source.

Scoold is extremely flexible and can run on various platforms, including Heroku, DigitalOcean, AWS, Azure, or any VPS hosting provider. It's lightweight, with approximately 7000 lines of code, and the backend is managed by a separate service called Para. What's more, Scoold doesn't require a database, and the controller logic is kept simple because all the heavy lifting is delegated to Para. This makes it easy to read and learn, even for junior developers.

In short, Scoold is an ideal choice for teams looking for a powerful Q&A and knowledge-sharing platform that is both flexible and easy to use.


Scoold has two editions: the free community edition, which anyone can download, install, and use at no charge, and Scoold Pro, the paid version of Scoold with premium features that make it the perfect knowledge-sharing platform for your company or team.
