We just released 𝚛𝚎𝚊𝚌𝚝-𝚋𝚎𝚜𝚝-𝚙𝚛𝚊𝚌𝚝𝚒𝚌𝚎𝚜, a repo for coding agents. React performance rules and evals to catch regressions, like accidental waterfalls and growing client bundles. How we collected them and how to install the skill ↓ vercel.com/blog/introd...

Prompt injection is sometimes called an "unsolvable". But we shouldn't give up like that. I've been on a mission to introduce hard security boundaries into AI agents and this is the next step: What if compromised MCP tools couldn't just passively prompt inject your app?

Search 1M+ GitHub repositories from your AI agent using Grep's MCP server. Your agent can now reference coding patterns and solutions used in open source projects to solve problems and answer questions. vercel.com/blog/grep-a...

I am delighted to announce that @vercel.com are investing in Nuxt! they are backing our vision of the open web, hiring me as well as other core team members (@atinux.com, @pi0.io + @antfu.me), to continue to work full time on Nuxt we remain independent — and our vision and ethos are not changing 💚

NuxtLabs, creators of Nuxt and Nitro, are joining Vercel. Same license, roadmap, and open governance, but now in a joint mission to build the best web.

Building AI agents (and workflows) doesn't have to be complicated. In fact, it's more approachable than you might realize. Hear practical advice from Vercel CTO @industrialempathy.com on building agents. vercel.com/blog/the-no-...

I'm traveling to Berlin next week and we're doing a Vercel meetup to celebrate the opening of our new Berlin office. I have a whole queue of blog posts about agents coming out and will be turning them into a lightning talk, and we'll have a panel, etc. The usual! partiful.com/e/9Is88RwZV9...

I finished university in 2004 and made a big stupid mistake: I wrote my thesis in German. I've literally been sad about this ever since. But AI to rescue: I dusted off an old PDF and had Gemini Pro translate it to English

Does anyone know the status of the Private State Token API? It seems shipped in Chrome but the demos appear broken and it doesn't look like Google shipped a generic issuer like Apple did for Private Access Tokens.

I just remembered how an internet mob chastised the Google intern who wanted to ship an async version of Local Storage using tech that allowed shipping Chrome feature using only JS knowledge. Both the feature and the underlying tech was killed. Imagine what could have been.

Fingerprinting is bad for privacy because it is out of user control. The villainification of browser cookies has pushed the world into a direction that is objectively worse for users. Cookies you can delete, auto-rotate, scope per site. Fingerprints stay with you ico.org.uk/about-the-ic...

Corporate organizations are distributed systems! My new blog post somewhere between tautology, cause of course they are, and hot take. But I think I might have stumbled over a helpful framing to manage risk & velocity when shipping software in larger teams www.industrialempathy.com/posts/organi...

Most folks outside the US don't realize that Fahrenheit is a super intuitive temperature unit. The degrees Fahrenheit, represent the maximum miles per hour you can drive safely at the temperature

I was randomly looking at the Vercel Firewall for my personal site. Turns out a small attack was mitigated. I then looked at our global dashboard, and, indeed, the attacker only hit my site and they got a total of 19 requests through before they were blocked. What have I done to you, attacker?

Vercel Remote Cache is now free for all plans. Never do the same work twice in your Turborepo or Nx repository with a shared store of build outputs and logs for your team. vercel.com/changelog/fr...

Right now Vercel responds with your project's HTML 404 response for all system-identified 404s (for functions/APIs you control the response directly). How would you feel if we changed it such that we responded with a generic response if the client doesn't expect HTML?

Vercel TypeScript SDK • Full type safety for accessing the Vercel REST API with Zod schemas • New documentation for every function, argument, and type • Better tree-shaking support with optional standalone functions vercel.fyi/sdk

You can't make this up: The spec for SSRing web components is itself not isomorphic. It only works when running through the document parser, but not innerHTML. Respectively, the code needs to know where it is running and use vastly different code paths.

I really enjoyed the excuse^H^H^H^H^H^Hopportunity to chat with @industrialempathy.com! Many lessons, some counter intuitive, that lead to v0, the AI SDK, and much more. Thanks for sharing, Malte!

A trained LLM can figure out the sloppiest web site because it turns out humans are predictably sloppy. And all our content has been neatly tagged with meta data in hopes of being blessed by the Google algorithm. But yes, please, let's argue the merits of web components for five more seconds

We shipped streaming support for Python on Vercel. PHP, Ruby, Bun, Deno, Go, are just around the corner now that we ported a 2nd language to use Vercel's new rust-based runtime which provides for better multi-concurrency, streaming, unlimited logging, and other features vercel.com/changelog/st...

Hey @danabra.mov, could you connect me with someone from your team responsible for crawling OG data. Every so often this triggers Vercel's DDOS protection. I'd love to discuss how we can make this work better going forward!

Random insight: The website was slower because of the theme picker. Why? The site had a color and background transition (not GPU accelerated) on the theme picker for when a selection is made.  🧵

What are all the reasons "real user metrics" for Core Web Vitals would differ from Google's PageSpeed Insights? I'll start: - RUM data may include non-Chrome browsers (For LCP and INP they would all be Chromiums) - Google only counts users who have Chrome sync on and opted into data sharing

I still remember taking Google's "life of a query" course during onboarding that taught you a little bit about everything vertically through the stack for a search query. Similarly, Vercel has a "life of a request" course and here is the blog post version of it vercel.com/blog/life-of...
