What Codesandbox is
CodeSandbox spent years making browser-based development environments resume instantly, and the SDK sells that infrastructure directly: microVMs that hibernate to a memory snapshot, resume with processes intact, and fork cheaply from any snapshot. Together AI acquired the company in 2025. The snapshot-and-fork model is the most mature in this roster, and pricing is credit-based rather than hourly.
