In-Application Sandboxing with Web Workers

A design rationale.

For the past fews years, the Web has been shifting control to the client. Given the limitations of remote services, developers are now looking for ways to "unhost" static applications – that is, break the dependency on remote servers while still using the Web platform.

One untapped technology for client-side control is the Web Worker Sandbox. This API lets the Page load, execute, and destroy separate Worker threads which use their own Virtual Machines. By using Worker Sandboxes to drive behavior, the Web can give users the choice of which software they run together, shifting development from a centralized SaaS model into a distributed and free (as in freedom) script-sharing model.

Worker Sandboxes can Execute Arbitrary Code
