Vercel CLI as a self-updating binary with zero external dependencies. Our CLI is one of the key interfaces enabling the 'cloud for agents'. This solves a huge bottleneck, as we ship changes to our CLI more than ever, and it's embedded in more places than ever. Fun fact: we built 𝚙𝚔𝚐¹ yeaaars ago in service of this vision. I didn't want customers to have to worry about Node.js over here, and the CLI package over there. We deprioritized it because Git and Web took off massively, and CLI usage was more sporadic. Now the situation is inverted. Every day, I hear from customers discovering Vercel after OpenClaw, Claude Code, or Codex not only introduce, but also onboard users to our agentic infrastructure. Our CLI (as well as our MCP and SDKs) is a key enabler of this new wave. ¹ http://github.com/vercel/pkg

Excellent model, particularly impressive in visual tasks. Give it a try

I watched the team dream up a static design with AI, then bring it to life in WebGPU shaders in less than a day. How can you not be excited about software development in 2026 😁 You can just ship beautiful things. http://nextjs.org/nights

The Deployments list was one of the earliest views I built on the (zeit) platform. One of the earliest 'acid tests' of Next.js was whether it could handle the dynamism of an app and the speed of a website, in one framework. Redesigning a view that's so heavily depended on is no small feat. While I didn't build this one, it was fun to be flagged-in to opine on the many variations the team tested to get this out 😁

Vercel protects your agents' deployments behind SSO like @Okta. Even Production ones, giving you a secure 'intranet' of apps generated with @v0, Codex, Claude, etc. It's all fun and games until your agent gets 𝟺𝟶𝟷 𝚄𝚗𝚊𝚞𝚝𝚑𝚘𝚛𝚒𝚣𝚎𝚍 from the deployment *it just made* though 😂 The solution: 𝚟𝚎𝚛𝚌𝚎𝚕 𝚌𝚞𝚛𝚕. By just prefixing 𝚟𝚎𝚛𝚌𝚎𝚕 or 𝚟𝚌 you unblock your agent and yourself to easily 𝚌𝚞𝚛𝚕 any URL you have access to within the Vercel ecosystem.

If you become exceptional at managing agents, but are also exceptional in your understanding of the fundamentals, you will be unstoppable. We all prefer to work with masters of their craft. What’s new: you can’t afford to miss out on the amplification agents have on your output

𝚗𝚙𝚡 𝚍𝚎𝚎𝚙𝚜𝚎𝚌 We're introducing an open-source agent orchestrator for deep security reviews.

Coding agents can now find critical vulnerabilities in minutes that would take teams of people months (if they can spot them at all). Since 𝚍𝚎𝚎𝚙𝚜𝚎𝚌 is optimized to work with Vercel Sandbox, you can effectively harness the power of thousands of agents scrutinizing your codebase in parallel. I encourage you to try this on your repositories. BTW: If you run an OSS project and want us to sponsor a run, my DMs are open.

Coding agents will be the foundation of all superintelligence. At a minimum, coding ability is indistinguishable from 'proficiency with computers'. Great coding agents like Claude Code master bash, filesystems, configuring and installing programs… But it's also about self-improvement. A coding agent has the ability to examine its source, its state, its skills, its instructions… it can propose changes to itself (with human supervision and audit trail, I recommend), or even mutate itself directly. In retrospect, this should be obvious. "What I cannot create, I cannot understand". Coding fluency has given models a deeper understanding of all computer and knowledge work. To master programs, you must be able to create them.

I want to keep everyone updated on the details of the security investigation. The team performed an in-depth analysis to search for root causes and to better understand the behavior of the threat actor. We cast a very wide net, pulling and processing nearly a petabyte of logs of the entire Vercel Network and API, extending well beyond the initial Context[.]ai compromise. We now understand that the threat actor has been active beyond that startup's compromise. Threat intel points to the distribution of malware to computers in search of valuable tokens like keys to Vercel accounts and other providers. Once the attacker gets ahold of those keys, our logs show a repeated pattern: rapid and comprehensive API usage, with a focus on enumeration of non-sensitive environment variables. As a result: ◾We've deepened and widened our collaboration with partners across the industry, like Microsoft, AWS and Wiz, to further protect the broader internet. ◾ We've notified other suspected victims of this threat actor, independent of this event, encouraging them to rotate credentials and adopt best practices. We've also shipped a bunch more product enhancements. I'm extremely thankful to our team and industry partners for working around the clock. For more details on the ongoing investigation, refer to our security bulletin: https://vercel.com/kb/bulletin/vercel-april-2026-security-incident

I’m so encouraged by the way our team and industry peers have shown up to protect the internet. We’ve now shipped over 20 product improvements across Dashboard and CLI to help your security posture. Easier to set up MFA, audit your Environment Variables, Activity logs and more

Whether design belongs in Figma or Claude Design is a distraction from a bigger shift. 1️⃣ Design will become autonomous. More helpful to think of it as 𝙳𝙴𝚂𝙸𝙶𝙽.𝚖𝚍, used by your coding agents running your software factory. 2️⃣ Specialized “personal” design tools generated by teams will proliferate. Design is a capability, not a tool. I agree with @rsms that there are many facets of design, and multiple tools are required. I love prompting in @v0 and it’s become the place where I can channel my inspiration, explore, communicate. But I’m also seeing a new generation of products that use the v0 Platform API or Sandbox and put design on autopilot. There are next-generation agents like @tryflint and http://trybloom.ai generating design & brand systems and maintaining them autonomously. Flint can even keep your website and content up to date and its design consistent. No human prompting needed. From this we will see the emergence of fully autonomous companies with agents like http://nanocorp.so and http://durable.ai, which go a step further and grow and advertise your business. tl:dr; The future looks very different from the present. AI is a true discontinuity. The “here’s the existing thing but with AI and ${jobTitle} is cooked” is short-sighted.

The hardest thing about agents and backends is durability. @workflowsdk fixes this. That LLM you're calling *will* go down. That service *will* rate limit you. That database *will* unexpectedly slow down. You *will* get paged 💀 I've been looking for a unicorn for a decade. I wanted the level of reliability of combining stuff like SQS / Kafka / microservices, and I absolutely did not want *that* at the same time 😂 Truly reliable systems like that are notoriously difficult to reason about, to develop locally, to test, to simulate, to deploy… Workflow SDK solves that without compromises. We're doing what Next.js did for the frontend, but for one of the most important problems of the new generation of backend applications. Notably, Workflow SDK has an incredible self-hosting and multi-cloud story from day 0. We've taken amazing lessons from Next.js and poured them into the many Worlds (adapters) you can deploy to. Congrats to Pranay and the Workflow team on a generational ship: http://vercel.com/blog/a-new-programming-model-for-durable-execution

The rate of progress in AI is relentless. You can capture the upside of its volatility with @aisdk and @vercel AI Gateway. Congrats to @anthropicai on another banger ship, but @xai, @openai, and @googleai are coming. Gonna be a fun year.

This is what the future of design looks like. Not just this specific tool¹, but the fact that every team in the world is now is empowered to build their own 'design factory'. Shader Lab was built with Claude Code, @threejs, @nextjs, and @vercel. To the exact needs, vision, and specification of @basementstudio. Every time we work on a project with them, we get a glimpse of an arsenal of internal tools they've deployed. Some built specifically for a project, some more general purpose. It's now easier to generate software re-assembling powerful building blocks, than searching and procuring the right SaaS for the job. ¹ though it's a banger

The software factory is the product: http://open-agents.dev

Today we're open sourcing http://open-agents.dev, a reference platform for cloud coding agents. You've heard that companies like Stripe (Minions), Ramp (Inspect), Spotify (Honk), Block (Goose), and others are building their own "AI software factories". Why? 1️⃣ On a technical level, off-the-shelf coding agents don't perform well with huge monorepos, don't have your institutional knowledge, integrations, and custom workflows. 2️⃣ On a business level, the moat of software companies will shift from 'the code they wrote', to the 'means of production' of that code. The alpha is in your factory. Open Agents deploys to our agentic infrastructure: Fluid for running the agent's brain, Workflow for its long-running durability, Sandbox for secure code execution, AI Gateway for multi-model tokens. (Because of our focus on Open SDKs and runtimes, this codebase is a gem even if you're not hosting on Vercel.) TL;DR: if you're building an internal or user-facing agentic coding platform, deploy this: https://vercel.com/templates/template/open-agents

Vercel Sandbox is now the #1 fastest microVM-based Sandbox. We’ve also heard from customers migrating that beyond “in the lab” benchmarks, our real-world performance & reliability are second-to-none.

Agentic Infrastructure is the future of the cloud ① For coding agents If you use Claude Code, Codex, Cursor, you need infra that 'clicks' for your agents, not just devs. ② To deploy agents Pages → Agents. Long-running compute, sandboxes, and our token delivery network are the building blocks of this new kind of software. ③ Itself an agent Vercel is beloved because it's self-configuring (serverless). Add to that: self-healing, self-optimizing, self-securing. The agent holds the pager. ⟁ It's a triple-entendre that works. I highly recommend the read. Agentic Infrastructure will make existing companies more efficient and support the next generation of AI-native startups.

The best outcome for humanity is many strong AIs competing for the top spot. Vercel is proudly powering http://meta.ai and the infrastructure that made today's model release possible.

The web's brightest days are ahead. 1️⃣ The web is AI's natural medium. LLMs are proficient in web tech. The browser is now everyone's IDE. No 'App Store' bs. 2️⃣ As we approach coding superintelligence, powerful low-level web APIs are maturing: WebGPU, HTML in Canvas, WebAssembly. The performance ceiling of the web will vanish, and you'll witness the most impressive, whimsical, and multi-dimensional pages and apps. 3️⃣ Generative UI is AI's final form. The web will be the birthplace of "AGUI". Each hyperlink providing a just-in-time, beautifully personalized experience. If you bet on the web, you bet on the right horse.

Created a flag on the moon based with hyper-realistic physics with @v0: http://v0-moon-flag.vercel.app. The flag is simulated as a grid of particles connected by springs (cloth simulation). It's influenced by gravity, wind, air resistance. The initial approach v0 one-shotted was quite simplistic, but giving it references to more sophisticated approaches in C++ and Rust quickly improved it. It was mind-blowing it to see it deeply understand the physics and port new ideas across languages. It simulated a real sun for lighting, and procedurally generated moon-like terrain with craters. I found a sick free texture on Reddit that I uploaded and it layered on top. Another epic moment was watching it improve performance. It seamlessly moved the physics simulation to a Web Worker. (Kinda cool to see given we just improved support for them in Turbopack 😉)

When Opus 4.5 came out, it was a one-way door to a new way of engineering. Agents now do most of our coding. Knowing the inherent flaws and over-confidence of LLMs, we sent a clear message to our teams. Vibing and mission-critical infrastructure don’t go together. We’re sharing some of our early internal guidance in how we’re “agenting responsibly”, prioritizing security, durability, and availability at all times. https://vercel.com/blog/agent-responsibly

Some people have been contemplating an idea for years, maybe decades. Obsessing, attempting, discarding, agonizing, retrying. Some of these ideas are unpopular, niche, impractical. Not obviously capitalizable. They live on in the inventor's mind. In 2026, millions of these ideas will come to life thanks to superintelligent coding agents. AI doesn't get tired. It amplifies the individual, and for better and sometimes for worse, it always takes you seriously. "Great idea. Splendid. Wow. You're absolutely right." A world of digital wonders awaits us. This world will disproportionally disfavor the boldest ideas. Software that once seemed impossible will be one hyperlink away. I can't wait to see it.
