Vercel Labs released an open-source reference app for building background coding agents that run as durable workflows on Vercel. The three-layer architecture (web interface, agent workflow, sandbox VM) supports chat-driven coding, isolated virtual sandboxes, repo cloning, and voice input. Unlike monolithic agent systems, agents persist beyond single request lifecycles with independent sandbox hibernation and resumption.
