Open Agents — Open-Source Cloud Coding Agent Platform by Vercel Labs
Vercel Labs' open-source reference app for building and running background coding agents in the cloud — chat, isolated sandboxes, durable workflows, GitHub integration, and auto-commit/PR creation without keeping your laptop online.
Vercel Labs' forkable cloud coding agent: chat drives the task, an isolated sandbox runs it, and Workflow SDK keeps it durable.
What is it?
Open Agents is an open-source reference app from Vercel Labs for building and deploying background coding agents entirely in the cloud. You send it a chat message, it writes and executes code in an isolated sandbox VM, then optionally commits the changes and opens a pull request — no local machine required.
How does it work?
Three layers work together: a Next.js web UI handles auth, sessions, and streaming chat; the agent runs as a durable Workflow SDK job (with automatic checkpointing and resumability) that lives outside the sandbox and issues file reads, shell commands, and git operations via tools; the Vercel Sandbox VM provides the isolated execution environment. Multi-model access comes through AI Gateway, and session sharing via read-only links is built in.
Why does it matter?
Most coding agent demos are hosted black boxes or local scripts that die when you close the terminal. Open Agents gives you the full forkable stack — web UI, agent runtime, sandbox orchestration, and GitHub integration in one repo. With 1.8k stars and 900+ commits it has real adoption, and it is the reference implementation Vercel uses to demonstrate its own agent infrastructure.
Who is it for?
Developers who want to build, self-host, or customize a cloud coding agent on Vercel.
