Over the past few years, we’ve seen developers push the boundaries of what’s possible with real-time communication — tools for collaborative work, massive online watch parties, and interactive live classrooms are all exploding in popularity. We use AI more and more in our daily lives. Text-based interactions are evolving into something more natural: voice and video. When users interact with the applications and tools that AI developers create, we have high expectations for response time and connection quality. Complex applications of AI are built on not just one tool, but a combination of tools, often from different providers which requires a well connected cloud to sit in the middle for the coordination of different AI tools. ...

As the Internet has become enmeshed in our everyday lives, so has our need for speed. No one wants to wait when adding shoes to our shopping carts, or accessing corporate assets from across the globe. And as the Internet supports more and more of our critical infrastructure, speed becomes more than just a measure of how quickly we can place a takeout order. It becomes the connective tissue between the systems that keep us safe, healthy, and organized. Governments, financial institutions, healthcare ecosystems, transit — they increasingly rely on the Internet. This is why at Cloudflare, building the fastest network is our north star. ...

Today, we are announcing the 1.0 release of the Cloudflare Vite plugin, as well as official support for React Router v7! Over the past few years, Vite’s meteoric rise has seen it become one of the most popular build tools for web development, with a large ecosystem and vibrant community. The Cloudflare Vite plugin brings the Workers runtime right into its beating heart! Previously, the Vite dev server would always run your server code in Node.js, even if you were deploying to Cloudflare Workers. By using the new Environment API, released experimentally in Vite 6, your Worker code can now run inside the native Cloudflare Workers runtime (workerd). This means that the dev server matches the production behavior as closely as possible, and provides confidence as you develop and deploy your applications. ...

Today, we’re announcing support for MySQL in Cloudflare Workers and Hyperdrive. You can now build applications on Workers that connect to your MySQL databases directly, no matter where they’re hosted, with native MySQL drivers, and with optimal performance. Connecting to MySQL databases from Workers has been an area we’ve been focusing on for quite some time. We want you to build your apps on Workers with your existing data, even if that data exists in a SQL database in us-east-1. But connecting to traditional SQL databases from Workers has been challenging: it requires making stateful connections to regional databases with drivers that haven’t been designed for the Workers runtime. ...

We first announced the Cloudflare adapter for OpenNext at Builder Day 2024. It transforms Next.js applications to enable them to run on Cloudflare’s infrastructure. Over the seven months since that September announcement, we have been working hard to improve the adapter. It is now more tightly integrated with OpenNext to enable supporting many more Next.js features. We kept improving the Node.js compatibility of Workers and unenv was also improved to polyfill the Node.js features not yet implemented by the runtime. ...

By Cheng Xie, Bryan Shultz, and Christine Xu In a previous blog post, we described how Netflix uses eBPF to capture TCP flow logs at scale for enhanced network insights. In this post, we delve deeper into how Netflix solved a core problem: accurately attributing flow IP addresses to workload identities. A Brief RecapFlowExporter is a sidecar that runs alongside all Netflix workloads. It uses eBPF and TCP tracepoints to monitor TCP socket state changes. When a TCP socket closes, FlowExporter generates a flow log record that includes the IP addresses, ports, timestamps, and additional socket statistics. On average, 5 million records are produced per second. ...

Postgres for Agentic AI—Now in the Cloud (Sponsored)If you’re building LLM-powered features, you don’t need another black box. pgai on Timescale Cloud gives you full control over your vector data, memory, and retrieval logic—inside PostgreSQL. Everything runs in one place, with SQL and the tools your team already uses. From prototype to production, it's built to scale with you. ...

<div> <h2>Free as in beer</h2> <a href="#free-as-in-beer"> </a> </div> <p>In acknowledgement of its pivotal role in building distributed applications that rely on regional databases, we’re making Hyperdrive available on the free plan of Cloudflare Workers!</p><p><a href="https://developers.cloudflare.com/hyperdrive/"><u>Hyperdrive</u></a> enables you to build performant, global apps on Workers with <a href="https://developers.cloudflare.com/hyperdrive/examples/"><u>your existing SQL databases</u></a>. Tell it your database connection string, bring your existing drivers, and Hyperdrive will make connecting to your database faster. No major refactors or convoluted configuration required.</p><p>Over the past year, Hyperdrive has become a key service for teams that want to build their applications on Workers and connect to SQL databases. This includes our own engineering teams, with Hyperdrive serving as the tool of choice to connect from Workers to our own Postgres clusters for many of the control-plane actions of our billing, <a href="https://www.cloudflare.com/developer-platform/products/d1/"><u>D1</u></a>, <a href="https://www.cloudflare.com/developer-platform/products/r2/"><u>R2</u></a>, and <a href="https://www.cloudflare.com/developer-platform/products/workers-kv/"><u>Workers KV</u></a> teams (just to name a few). </p><p>This has highlighted for us that Hyperdrive is a fundamental building block, and it solves a common class of problems for which there isn’t a great alternative. We want to make it possible for everyone building on Workers to connect to their database of choice with the best performance possible, using the drivers and frameworks they already know and love.</p> <div> <h3>Performance is a feature</h3> <a href="#performance-is-a-feature"> </a> </div> <p>To illustrate how much Hyperdrive can improve your application’s performance, let’s write the world’s simplest benchmark. This is obviously not production code, but is meant to be reflective of a common application you’d bring to the Workers platform. We’re going to use a simple table, a very popular OSS driver (<a href="https://github.com/porsager/postgres"><u>postgres.js</u></a>), and run a standard OLTP workload from a Worker. We’re going to keep our origin database in London, and query it from Chicago (those locations will come back up later, so keep them in mind).</p> <pre><code>// This is the test table we're using // CREATE TABLE IF NOT EXISTS test_data(userId bigint, userText text, isActive bool); ...

You can now add a Deploy to Cloudflare button to the README of your Git repository containing a Workers application — making it simple for other developers to quickly set up and deploy your project! The Deploy to Cloudflare button: Creates a new Git repository on your GitHub/ GitLab account: Cloudflare will automatically clone and create a new repository on your account, so you can continue developing. Automatically provisions resources the app needs: If your repository requires Cloudflare primitives like a Workers KV namespace, a D1 database, or an R2 bucket, Cloudflare will automatically provision them on your account and bind them to your Worker upon deployment. ...
