Sandstorm.io is an open source project that aims to make hosting web-based productivity apps in a secure and user-friendly way. Apps, documents, chat rooms, and more are saved in a secure sandbox called “grains,” protecting users from security vulnerabilities. Every Sandstorm app is available on the App Market for easy installation, and all apps come with automatic updates. Maintaining data privacy and regulatory compliance is also easy, as Sandstorm manages access control on every document. This platform is ideal for individual users, businesses, and developers who need secure, user-friendly apps and complete control over data storage.
