Sandboxie Plus is a sandbox-based isolation software for Windows that creates secure virtual environments in which applications can run without permanently modifying the host system's drives or registry.
The tool addresses the need to safely test untrusted programs and browse the web without risking system compromise. It works by creating isolated virtual environments where applications execute in containment, unable to affect the host or other sandboxes. Users can create virtually unlimited sandboxes, run them individually or simultaneously, and execute multiple programs within a single sandbox instance.
Sandboxie suits developers and end users who need to test software safely, security researchers evaluating potentially malicious code, and anyone browsing untrusted websites. The project is available in two editions—Plus with a modern Qt-based user interface supporting newer features, and Classic—both sharing the same core isolation components and security level. This is a community fork maintained after the source code was released, rather than the official continuation of previous development.
The project maintains a substantial base of real-world adopters, as evidenced by the fact that almost all open issues are raised by outside users rather than the core team. Maintainers typically respond to new issues and pull requests within a day. Work in the issue tracker is dominated by confirmation requests, fixes marked for the next build, and feature requests from the community.
