As the world’s leading in-person car auction enterprise, Mecum Auction Company has sold some of the most famous vehicles in the world. And while their digital platform had capably evolved over the years, it was hitting its limit, hindering their ability to create listings quickly. With the help of digital agency Americaneagle.com, Mecum adopted a new, composable stack—giving them confidence that their website would be fast, performant, and reliable.  

Hello! I’m Aryan. I am currently a student at UC Berkeley, studying Electrical Engineering and Computer Science (EECS). This summer, I had the opportunity to be an intern at Vercel. It’s been an unforgettable experience. As my internship comes to a close and I head back to school, I want to share a behind-the-scenes look at what an internship at Vercel is like. How it all started I started programming when I was in 8th grade. A major inflection point in my journey was competing in my first hackathon, Hack Cupertino 2018. This hackathon changed my mental model of the world. Instead of being a consumer of applications, I could become a creator. I could transform my ideas into code and publish it on the internet for others to use. Coding truly felt like a superpower. Throughout high school, I continued cultivating my development skills by interning at a f...

React 19 is near. The React Core Team announced a React 19 release candidate (RC) this past April. This major version brings several updates and new patterns, aimed at improving performance, ease of use, and developer experience. Many of these features were introduced as experimental in React 18, but they will be marked as stable in React 19. Here’s a high-level look at what you need to know to be ready.

McKinsey's latest AI survey shows 65% of organizations now regularly use AI — nearly double from just ten months ago, with many using it to increase efficiency in critical areas like customer support. At Vercel, we integrated AI into our support workflow. Our AI agent reduced human-handled tickets by 31%, allowing us to maintain high support standards while serving a growing customer base. The challenge: balancing support quality with growth Customer support teams routinely handle a diverse range of customer inquiries, many of which involve repeatable processes. These can range from simple tasks like guiding customers to specific documentation pages, to helping customers through the process of configuring their domain. The landscape of customer support is pointing organizations toward building AI-powered chatbots as a critical component of their customer support strategy. Accordin...

In 2014, the OpenID Foundation introduced a new standard for authenticating people online, known as OpenID Connect (OIDC). This standard was initially created to simplify the authentication process for users, providing a streamlined and secure way to log into various services. Today, Vercel leverages OIDC to enhance the security of backend connectivity, enabling developers to replace long-lived credentials with more secure, temporary tokens.

Last year, we added storage solutions to our platform, introducing our first-party Blob and Edge Config, as well as partner solutions like Postgres by Neon and KV by Upstash. We heard your feedback—you want more providers and different types of integrations. Today, we’re launching the first version of the Vercel Marketplace. It supports storage solutions from Supabase, Redis, and EdgeDB, at the same price as going direct. These integrations come with features like integrated billing, direct connections to provider consoles, and more.

As publishers of leading independent games, the team at Devolver is never short on work. But as a small engineering team, they felt limited by their clunky infrastructure and were spending more time on system management than they needed. With Vercel, the Devolver team was able to cut time spent on system management and configuration by more than half, allowing them to bring game websites to life 73% faster. Soon after adopting Vercel, the team was even able to launch five websites during a 30-minute press conference without any issues.

Recently, there was an issue affecting our customers when trying to purchase a domain containing non-English characters. This problem became apparent when these domain purchases consistently failed, creating a significant roadblock for users wanting to expand their online presence with internationalized domain names (IDNs). The bug background The root of the problem was the encoding process. Domains with non-English characters are encoded in Punycode format. This encoding allows for a wide range of international characters to be represented using the limited character set of the ASCII standard. However, when we sent these encoded domains to our domain registrar, OpenSRS, we encountered cryptic error messages that gave little indication of the underlying issue. Through a deep dive into the OpenSRS documentation, we ...

In today's AI-driven landscape, your business's competitive edge lies in how effectively you integrate AI into your product and workflows. This guide focuses on three critical aspects of building scalable AI applications: Choosing and implementing AI models as they release Managing and preparing your unique data for AI Developing and optimizing future-proof infrastructure Choosing the right provider Choosing AI providers, such as OpenAI, Anthropic, and Google—or even fine-tuning or rolling your own model—can be daunting. While each has pros and cons, the Vercel AI SDK offers the flexibility to work with multiple providers, allowing you to take advantage of each of their best features without being locked into a s...

On August 7, 2024, Vercel's Edge Middleware and Edge Functions experienced a significant outage affecting many customers. We sincerely apologize for the service disruption. Vercel’s platform is designed to minimize the risk of global downtime. As standard practice, we use staggered rollouts for both code and configuration changes. Every aspect of our infrastructure is designed to gracefully fail over to the next available region in the event of an incident, and ensures no single point of failure across infrastructure components. However, on Wednesday, an upstream provider for a subset of our compute infrastructure went into a globally erroneous configuration state. This event tested our infrastructure's resilience and how we respond to a global provider failure. Let’s break down what happened, how we responded, and the steps we’re taking to eliminate this as a possible failure mode.

Implementing AI in your business can be challenging due to the rapid pace of change, the complexity of integration, and the need for specialized skills.

Companies like Tome, Chick-fil-A, Chatbase, Runway, and Suno are already using these tools to bring AI into their apps and workflows.
