Open Agents is an open-source reference application from Vercel Labs for building and running background AI coding agents — the kind that work on tasks without keeping your laptop involved. It bundles the web UI, agent runtime, sandbox orchestration, and GitHub integration in one deployable package. The agent runs outside the sandbox VM and interacts with it through tools, enabling sandbox hibernation and resumption without interrupting agent execution. The stack is built on Next.js with Vercel's Workflow SDK for durable multi-step execution, supports streaming and cancellation, and exposes ports for live preview. Agents can read files, run shell commands, search the web, manage tasks, clone repos, commit and push, and open PRs automatically. Optional voice input via ElevenLabs transcription is included. Sessions are shareable via read-only links. This is Vercel making a direct play for the agentic coding infrastructure market, positioning their platform as the natural host for background agents. By open-sourcing the reference implementation, they're lowering the barrier for teams to self-host while also making Vercel the obvious deployment target. It's both genuinely useful for developers and a smart distribution strategy.

v0 by Vercel generates production-ready React components from natural language prompts. It outputs shadcn/ui + Tailwind code that you can copy directly into your Next.js project. Supports visual input from Figma, screenshots, and sketches.
Reviewer scorecard
“The architecture decision to run the agent outside the sandbox VM is clever and underappreciated — it means the execution environment and the reasoning layer can evolve independently. The built-in PR generation and Workflow SDK integration save weeks of plumbing for any team building coding agents.”
“The code quality is surprisingly good — real shadcn components, not generic divs with inline styles. Saves me 2-3 hours per UI component.”
“This is a reference app, not a production system — the security model for autonomous agents writing code and opening PRs to your repos deserves serious scrutiny before deployment. It's also tightly coupled to Vercel infrastructure, so 'open source' here really means 'open source, but runs best on our platform.'”
“Does one thing extremely well: turning ideas into working UI. It won't replace a designer, but it eliminates the blank canvas problem.”
“Background coding agents that work while you sleep are the next productivity frontier after the copilot wave. Vercel dropping a reference implementation lowers the activation energy dramatically. The teams that build on this pattern in 2026 will have a meaningful head start when fully autonomous software development becomes standard.”
“The read-only session sharing is a sleeper feature for async collaboration — reviewers can watch an agent work through a problem without needing access to the codebase. That's a genuinely new collaboration primitive that screenshot-sharing in Slack can't replicate.”
“As a creator, I can now prototype landing pages in minutes instead of hours. The Figma-to-code flow is a game changer for my workflow.”
