SANDSTORM

Sandstorm is an open source project built by a community of volunteers with the goal of making it really easy to run open source web applications... With Sandstorm, you do not get locked into walled gardens. You can mix and match apps from multiple developers with ease, and even throw in apps of your own as needed. Many Sandstorm apps are open source, which means you can modify them to suit you needs... Sandstorm makes it easy to adhere to security, regulatory, and data privacy requirements. Sandstorm manages access control on every document, so it can show who has access and allow you to revoke that access at any time. Self-hosting Sandstorm enables organizations to have complete control over where their data is stored.
