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

Meet the CI for agents

[Vercel @vercel]

Introducing Vercel CI

• Intelligently skips tasks with Turborepo
• 2-6× faster CI in our internal repositories
• Optimized for agents via Vercel MCP and CLI

After nearly 8 million tasks, we're excited for the future of agentic CI. In beta on all plans.

Grok Bot: agent-browser worked really well on my computer

Thanks @bot. You also work really well on my computer/phone

[Chris Tate @ctatedev]

fx in the cloud

Nice ship @z0oks 🐐

[Vercel Developers @vercel_dev]

fx × T3 Code: our open-source agent harness, fx, is now a built-in provider in T3 Code.

• Runs on web, desktop, and mobile
• Works with your existing models and skills

wterm is also now much faster, smaller and more efficient

Try the https://t.co/SzYHk89Lku demo on your iPhone Duo, powered by wterm, an open-source terminal emulator for the web, and Ghostty

Give your agent harness the power to generate images, video, speech and more

Shu will be the first to understand the universe

[Shu @shuding]

UI and math time! UI = f(props) is the most famous line in React. But that f is JavaScript, not math.

Inspired by @_chenglou’s Handwired project, I compiled a <Dashboard/> component into a real math function, and asked what becomes possible.

@RaillyHugo Nice

[Hunter ▲ @RaillyHugo]

New wterm 0.5.6 fixes & improvements

→ Resize keeps the saved cursor inside the grid
→ Exact truecolor, no palette rounding
→ Faster full-screen scrolling in the built-in core

[Chris Tate @ctatedev]

Personal assistants should actually be personal

[Browserbase @browserbase]

Introducing BELL, the complete OSS stack to build your own personal assistant.

@browserbase for browser infra
@eve by Vercel for harness
@thelinqapp for iMessage
@link by Stripe for payments

We're giving it $10,000 to make agentic payments, join the stream to spend our money.

A nice side effect of this:

As scriptc gets faster, tsc-ts gets faster, and vice versa

Improvements to either benefit both

tsc-ts continues to work standalone, too

[Chris Tate @ctatedev]

scriptc self-compiles
tsc-ts self-checks
scriptc compiles tsc-ts

and now tsc-ts checks scriptc

A compiler and type checker, both written in TypeScript

[Chris Tate @ctatedev]

Congrats $ANT

And thank you for continuing to push the frontier of what's possible for humanity

[Chris Tate @ctatedev]

This means more npm code works, with checks at supported type boundaries

https://t.co/7F5SKc01bw

[Chris Tate @ctatedev]

npm types can lie

scriptc can now check values crossing from npm packages into your typed code against their TypeScript declarations

→ Mismatches throw a runtime TypeError
→ No validation code added to your app

[Chris Tate @ctatedev]

&gt; Don't wait for your agents. Let them wait on you. If you worry about TTFT, you're probably doing something wrong. Lean into async. Give them bigger tasks, be more ambitous.

Yes

[Thorsten Ball @thorstenball]
