Introducing Vercel Labs Tools for devs in the AI era agent-browser, skills, json-render, deepsec, fx, just-bash, portless, vgpu and more We experiment in public: ship early, learn from feedback, and keep working on what people find useful We've been shipping under the Labs name for a while. Now, Labs is an official team at Vercel focused on exploring new capabilities and primitives that change what developers and agents can do. Here's what to expect: → Labs products: maintained, supported, built to be relied on → Active experiments: moves fast, expect rough edges and breaking changes → Past experiments: ideas that become new projects, make it into existing products, or teach us what to build next vercel.com/labs?experiment-i…

agent-browser v0.39.2 - Invalid policies now deny actions - Blocked redirects return errors - Fixed stalled network requests - Persistent CDP sessions - Safer clicks & element refs - Strict MCP arg validation - Fixed Eve & browser launch flags Thank you @raillyhugo, @mdlahfir, @aniketsauravv, @jerry543, @\cmpadden, @\holny, @\KimHyeongRae0, @\jin-2-kakaoent, @\asif786ka, @\tlq5l for your contributions! github.com/vercel-labs/agent…

This is how I scale agent swarms: a graph of agents that can spawn new agents and communicate with each other Below is what this looks like in practice Two key pieces make it possible: - Vercel Sandbox: Firewall¹ + Credentials Brokering - Vercel Connect²: GitHub + Slack access for the controller ¹ vercel.com/docs/sandbox/conc… ² vercel.com/docs/connect

Anything is possible

Duo is cool, I want one But hear me out @johnternus

New in agent-browser: snapshot --delta Returns only what changed since the last snapshot, instead of the whole page Below: 73x fewer tokens filling a form

The best part of Vercel was never just hosting your frontend It was how easy it is to ship We're bringing that same experience to backends, for developers and agents
