CodeSandbox vs Sandboxie Plus

CodeSandbox is a web and iOS service for creating isolated development environments that execute code. Its SDK can spin up environments programmatically, while microVMs can be started, cloned, or restored from snapshots within two seconds. Snapshots let work resume in the same sandbox after inactivity, and users can set the inactivity period before automatic hibernation. Multiple agents can run in parallel without interfering, and forking supports A/B testing of different agents. Tests can run inside sandboxes for CI/CD, with environments able to hibernate after completion. Sandpack provides live browser coding, Storybook Integration creates a playground for each story, and CodeSandbox lists a VS Code extension. The service says it can handle millions of concurrent VMs. CodeSandbox was founded in 2017, is headquartered in Amsterdam, and CodeSandbox BV is a Together AI company.

Sandboxie Plus runs Windows applications inside isolated environments designed to prevent permanent changes to the operating system. It supports controlled testing of untrusted programs and web surfing. Plus and Classic editions use the same core components and isolation level; Plus adds a Qt-based interface and features introduced after the project became open source. Snapshot Manager restores sandboxes to known states. Privacy-enhanced sandboxes hide locations that may contain personal data, while security settings restrict syscall elevation and device access. Windows Filtering Platform support applies firewall rules per sandbox, and DNS filtering can block or redirect selected domains. Storage can use AES-based encryption, although Sandbox Encryption requires the Advanced Feature Pack unless covered by an Eternal or Contributor certificate. Portable mode avoids system installation. Stable downloads include x64 Windows 7, 10, and 11, plus ARM64 Windows 10 and 11. A free personal-use plan is available.
