Open Agents

Open Agents is a web-based platform from Vercel Labs that lets you spawn coding agents that run indefinitely in the cloud. You describe what you want to build — say, a GitHub OAuth flow — and the agent autonomously writes code, runs commands, and commits the results. It's not a demo or a toy: each agent gets a full sandbox environment with filesystem, network, and runtime access, and it works until the job is done.

Under the hood, Open Agents combines several production-grade primitives from the Vercel ecosystem: the AI SDK for a unified interface across models, AI Gateway for routing requests with fallbacks and rate limiting, Sandbox for isolated ephemeral environments, and Workflow SDK for durable, resumable agent loops. Agents can delegate tasks between explorer and executor subagents, use shell commands, search files, and edit code. Work is automatically committed and pushed to a git branch, so nothing is lost when a sandbox expires. You can even reconnect to a running workflow from another client.

This tool is built for developers who want to offload coding grunt work to an AI that actually ships real code. It's especially useful for prototyping features, setting up boilerplate, or automating multi-step development tasks. Because it's open source and built on Vercel's infrastructure, it's transparent and extensible. If you've ever wished you could just describe a feature and have it built while you grab coffee, Open Agents is worth a look.
