With quick access to flexible infrastructure and innovative AI tools, startups are able to deploy production-ready applications with speed and efficiency. Cloudflare plays a pivotal role for countless applications, empowering founders and engineering teams to build, scale, and accelerate their innovations with ease — and without the burden of technical overhead. And when applicable, initiatives like our Startup Program and Workers Launchpad offer the tooling and resources that further fuel these ambitious projects. ...

Since the launch of Workers AI in September 2023, our mission has been to make inference accessible to everyone. Over the last few quarters, our Workers AI team has been heads down on improving the quality of our platform, working on various routing improvements, GPU optimizations, and capacity management improvements. Managing a distributed inference platform is not a simple task, but distributed systems are also what we do best. You’ll notice a recurring theme from all these announcements that has always been part of the core Cloudflare ethos — we try to solve problems through clever engineering so that we are able to do more with less. ...

Today, we’re launching the open beta of Pipelines, our streaming ingestion product. Pipelines allows you to ingest high volumes of structured, real-time data, and load it into our object storage service, R2. You don’t have to manage any of the underlying infrastructure, worry about scaling shards or metadata services, and you pay for the data processed (and not by the hour). Anyone on a Workers paid plan can start using it to ingest and batch data — at tens of thousands of requests per second (RPS) — directly into R2. ...

Super Slurper is Cloudflare’s data migration tool that is designed to make large-scale data transfers between cloud object storage providers and Cloudflare R2 easy. Since its launch, thousands of developers have used Super Slurper to move petabytes of data from AWS S3, Google Cloud Storage, and other S3-compatible services to R2. But we saw an opportunity to make it even faster. We rearchitected Super Slurper from the ground up using our Developer Platform — building on Cloudflare Workers, Durable Objects, and Queues — and improved transfer speeds by up to 5x. In this post, we’ll dive into the original architecture, the performance bottlenecks we identified, how we solved them, and the real-world impact of these improvements. ...

Writing clean, maintainable, and scalable code sounds easy as a requirement, but is a constant challenge when developing real-world applications.  As projects grow, the task becomes more complex. One way to simplify it is by identifying recurring design problems, which can be solved using appropriate design patterns. Design patterns are proven, reusable solutions to common software design problems. They provide best practices and structured approaches for solving recurring challenges. These patterns are not concrete implementations but templates or guidelines that can be adapted to specific use cases. ...

Apache Iceberg is quickly becoming the standard table format for querying large analytic datasets in object storage. We’re seeing this trend firsthand as more and more developers and data teams adopt Iceberg on Cloudflare R2. But until now, using Iceberg with R2 meant managing additional infrastructure or relying on external data catalogs. So we’re fixing this. Today, we’re launching the R2 Data Catalog in open beta, a managed Apache Iceberg catalog built directly into your Cloudflare R2 bucket. ...

Read replication of D1 databases is in public beta! D1 read replication makes read-only copies of your database available in multiple regions across Cloudflare’s network. For busy, read-heavy applications like e-commerce websites, content management tools, and mobile apps: D1 read replication lowers average latency by routing user requests to read replicas in nearby regions. D1 read replication increases overall throughput by offloading read queries to read replicas, allowing the primary database to handle more write queries. ...

Every cloud platform needs a secure way to store API tokens, keys, and credentials — welcome, Cloudflare Secrets Store! Today, we are very excited to announce and launch Secrets Store in beta. We built Cloudflare Secrets Store to help our customers centralize management, improve security, and restrict access to sensitive values on the Cloudflare platform. Wherever secrets exist at Cloudflare – from our developer platform, to AI products, to Cloudflare One – we’ve built a centralized platform that allows you to manage them in one place. ...

We’re excited to announce Workers Observability – a new section in the Cloudflare Dashboard that allows you to query detailed log events across all Workers in your account to extract deeper insights. In 2024, we set out to build the best first-party observability for any cloud platform. Since then, we’ve improved metrics reporting for all resources, launched Workers Logs to automatically ingest and store logs for Workers, and rebuilt real-time logs with improved filtering. However, observability insights have been limited to a single Worker. ...
