Run programs in an isolated sandbox on Windows
EN | 中文
Sandboxie is a sandbox-based isolation software for Windows NT-based operating systems that creates a secure operating environment in which applications can be run or installed without permanently modifying local & mapped drives or the Windows registry. An isolated virtual environment allows controlled testing of untrusted programs and web surfing.
Sandboxie allows you to create virtually unlimited sandboxes and run them alone or simultaneously to isolate programs from the host and each other, while also allowing you to run as many programs simultaneously in a single box as you wish.
Note: This is a community fork that took place after the release of the Sandboxie source code and not the official continuation of the previous development (see the [project history](#project-history) and [#2926](https://github.com/sandboxie-plus/Sandboxie/issues/2926)).
Sandboxie is available in two editions, Plus and Classic. They both share the same core components, this means they have the same level of security and compatibility. What's different is the availability of features in the user interface.
Sandboxie Plus has a modern Qt-based UI, which supports all new features that have been added since the project went open source:
