Built a physical simulation of a record player with WebGL2 and Web Audio. It's *shockingly* accurate: Instead of playing a song, it works by converting it into the physical shape of a groove. Then a simulated stylus rides those walls 384,000 times a second, and you hear the voltage that motion would induce in a cartridge. So the crackle, the pops, the wow/flutter, the dull inner grooves are natural byproducts of the simulation. You can also "DJ" the record. (The converted songs are in the public domain or CC-licensed. Code is linked for you to remix and re-deploy.)

So bullish on WebMCP
wterm now supports WebMCP Agents can use the terminals on your page → List, read, type, press keys → Opt-in per terminal, read-only mode → React, Vue, Svelte + vanilla → No DOM scraping or fake key events Below: 5 fx agents launch each other across 4 browser terminals

So cool!
Vercel MCP now shows deployments as an interactive card in ChatGPT and other clients that support MCP Apps. • Live deployment status • Build logs you can debug in the chat • A Visit button once the URL is ready Changelog →

Stateless sandboxes are the wrong benchmark. Agents are only useful if they have their workspace with them (identity, skills, repos, memories…) Vercel Sandbox team has been beautifully delivering on their latency & throughput SLOs, while prioritizing reliability and security. Doing this while shipping clusters in 19 (‼️) global regions, new features every week, and under immense amount of customer demand in the double digit growth percentage per week.

Vercel Sandboxes with Drives start 2.4x faster. • Median creation drops from 1.7s to 0.7s • p95 creation drops from 2.2s to 1.6s • No SDK upgrade or config changes needed

Securing the supply chain is one of our top priorities. When npm packages get hijacked, our system blocks their deployment, protecting your code and secrets from exfiltration.
Vercel now automatically blocks known malicious npm packages in builds before their install scripts can run, no action required.
Given the deserved attention this got we posted a security bulletin TL;dr: Vercel has completed the application of Linux kernel security updates to address CVE-2026-98432.
F1 is basically the perfect competition for our times. The celebration of extraordinary technology and extraordinary human ability. That’s what Vercel stands for! (also: winning)
20 years 68 days old. The youngest World Champion in history. Congratulations, Kimi Antonelli, 2026 F1 World Drivers' Champion. Vercel signed a partnership with @MercedesAMGF1, but we get to watch history:

Own your intelligence. Anyone that opposes this has something to sell you (perhaps your own intelligence back to you.) Local models need to continue proliferating. The “absolute unit” massive models may be out of reach for now locally, so your best option is to, indeed, keep your options open. Own your harness, data, connections, runtime: your agents. Embrace open source.

Working with Gemini on is hilarious 😂😂 Other than being SUPER EXCITED!, I've been testing it on two high complexity projects and it's doing great.

Turns out alchemical dreams were real. We converted sand into superintelligence. Who cares about gold… We transmuted the most ordinary into the most extraordinary.

The rate of improvement on is bewildering. It's now even smaller, faster and more token-efficient. We're continuously benchmarking and asking it to improve its own performance across open and proprietary models.

Next Native is coming. The whole world will be natively optimized in the coming months. Safe, performant, and cost-efficient.
We're prototyping native language support in Next.js, starting with Route Handlers and Proxy in Go. This gives you more options for CPU intensive workloads on the server, alongside your React app.

Vercelnetes or V8S for short
Daemons now support HTTP liveness checks. Vercel periodically requests a health endpoint in your daemon and restarts its container when the check fails.
Amazing technology is being developed and released at a rate humans can hardly keep up with. Agents are shipping software faster than we can yap about it.
