CodeSandbox vs nono

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.
