Made another thing!
New: agent-browser Contact Sheets
Agents can now debug UI bugs they couldn't see before
Record an interaction β get timestamped frames w/ changes highlighted
This signature appears then disappears
Instead of having identical before/after screenshots, agents see what happened

We collaborated with @HacktronAI to reproduce the libheif vulnerability in Next.js and responsibly disclose it to the maintainer.

When I might have sounded alarmist over the last few weeks, it was because I was aware @S1r1u5_'s excellent work here that is the perfect demonstration of our new reality:
- There is a vulnerability in a random image codec library
- This library is used by O(every app)
- There are many such libraries
- It was possible to find the vulnerability with now-well-behind-frontier models
- There are many such vulns and they will all be found over the next months
Vercel will do everything it can to do our part. This is why there have been more Next.js security releases over the last weeks and I expect the need to continue at this pace π«‘
On July 25, we hacked OpenAI.
Two bugs let us take over ChatGPT/Codex accounts of OpenAI employees (+some unaffiliated users) and reach connected services: Outlook, Slack, GitHub, etc.
We proved it with a PR in OpenAIβs internal codebase . It took us <72h. π§΅

agent-browser, now more human
--cursor
Visible pointers and click feedback
--human
Smooth, curved mouse movement / drags
For demos, bug repros, reviewing agent runs

For no particular reason, an appeal to OpenAI and Anthropic: Donate tokens and ideally meat proxies to systematically rewrite all commonly used C-based libraries like image and video codecs, database drivers, etc. in memory-safe languages like Rust.
There is an absolute tsunami of vulns being discovered. We have to act.

great end to @MarcosHernanz's internship
We closed 1,500 issues on ππππππ/πππ‘π.ππ in one month by building a πππππππππππ’ agent with @eve.
The workflow:
1. Search related work
2. Try to reproduce bugs across versions in a sandbox
3. Return context for review

Your Next.js app ships dozens of JavaScript chunks. Turbopack has to balance how many requests a page makes against how much code it ships.
Learn how it works and what's new in Next.js 16.3.

Vercel + TanStack
Vercel, like the web, is built on open standards and open source. That's why we're excited to partner with TanStack to power the next generation of apps and agents on Vercel.

I rebuilt an older Vercel book search demo with Next.js 16.3 Instant Navigations: next-books.dev
Instant Navigations lets server-rendered routes respond immediately when you click, even on a throttled connection:
πππππ πππ‘ππ²πππππ = {
ππππππ²πππππππππ: ππππ,
ππππππππΏππππππππππ: ππππ
};
Cache Components prerenders static, cached, and fallback UI. Partial Prefetching brings that reusable route UI to the browser before navigation.
Add ππππππππ={ππππ} when a link should also resolve its URL-dependent content before the click. Anything still missing loads on the server and streams into its Suspense boundary.
The filters use πππππππππππππ to fade the catalog while the server updates and ππππΎπππππππππ to apply the next filter values immediately.
Rebuilding the demo also improved initial loading. First Contentful Paint was 44% faster and Largest Contentful Paint was 33% faster than the original.
