CodeSandbox vs Daytona

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.

Daytona provides a secure, elastic runtime for executing AI-generated code and agent workflows. Its homepage states that sandbox creation takes under 90ms, and Daytona describes runtime isolation for code execution. Programmatic controls cover processes, file-system operations, Git integration, and built-in language-server support. SDK examples or interfaces are shown for Python, TypeScript, Ruby, Go, and Java. Listed uses include AI evaluations, code interpreter workloads, coding agents, and data analysis. The product's listed environments include API, Linux, macOS, self-hosted, web, and Windows; its CLI documentation supports macOS, Linux, and Windows. Documentation lists Claude, Cursor, and Windsurf as supported agents. Network options include IP and domain allow lists, outbound blocking, and chained proxies. Organization-scoped secrets are encrypted at rest and injected as placeholders into sandboxes, with plaintext substituted only for allowed HTTPS hosts. Daytona has free offerings and usage-based pricing; compute, memory, storage, and Windows rates are listed, while Enterprise pricing requires contacting sales.
