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

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
My workflow keeps evolving:
local agents → cloud agents →
cloud agents + cloud subagents
Latest is a graph:
- each gets own sandbox
- creds stay outside sandboxes
- agents can message each other
- github writes go through approvals
- interactive sessions survive disconnect
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

New from Vercel Labs: tsc-ts
TypeScript was written in TypeScript
Then rewritten in Go
We ported it back to TypeScript
Compiled it with scriptc
And it's 2-4x faster than tsgo
Type-checking vs tsgo:
→ VS Code: 4.2x faster
→ Sentry: 4.2x faster
→ TypeORM: 3x faster
→ tRPC: 2.8x faster
npm i tsc-ts

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
Run your backend on Vercel.
• Python is generally available
• Containers for other runtimes & system libraries
• Daemons for async jobs & background workers

Happy Ship Day

scriptc now supports NoThrow<T>
Detect new unhandled exceptions when your code or dependencies change
Get a compile-time error showing the throwing call path
Chris Tate retweeted
Our goal with a scriptc is to make compiled TS competitive with go and rust. That requires robust multi-threading primitives.
Notably, we are not extending JS. These programs run with the same semantics in node but in scriptc you get zero-copy immutable data structures into the worker
There will never be another year like 2026
This is the year everything changed. A defining moment in human history, with a clear before and after.
We're all part of it. And the whole thing is playing out right here on X. Wild.
