Sandstorm isolates each application workspace in its own sandbox, limiting the reach of application vulnerabilities and giving administrators fine-grained control over data sharing between applications. The capability-based sharing model lets users grant narrow access to individual documents.
One-click installation and automatic signed updates lower the operational burden of self-hosting compared with manual server administration. The open-source codebase allows independent audit and deployment without dependence on a vendor-operated service.
Sandstorm addresses users and organizations that want self-managed alternatives to mainstream cloud services, including privacy-sensitive teams and open-source adopters. Its catalog covers communication, file storage, task management, and collaborative editing use cases.
The venture-backed company phase ended without sustained revenue, and the project now advances as a volunteer-maintained effort. Evaluation should weigh the maturity of the application catalog and the pace of community maintenance against the autonomy benefits of self-hosting.
Sandstorm is an open-source system for installing and running web applications on self-managed servers. Each application runs in an isolated sandbox, and users install from an application marketplace with automatic updates.
The platform handles shared concerns such as authentication, sharing controls, and access policies across applications. An organization offering supports on-premises deployment with company login integration and organization-wide sharing policies.
