Claude Code for web: an asynchronous coding agent in a sandbox, without your laptop
Simon Willison tested Claude Code for web: Anthropic wrapped the local Claude Code experience in a hosted sandbox and made it usable from web and mobile. The important shift is not a more capable model, but a workflow change: coding agents become more valuable when they can run asynchronously and safely away from your laptop.
This is less a new editor and more delegation infrastructure. If an agent can run in isolation without unlimited filesystem and network access, we can finally talk about productivity without signing a security suicide note.
