Introducing Workers Unbound

Today, we are excited to announce the next phase of this with the launch of our new platform, Workers Unbound, without restrictive CPU limits in a private beta. We launched Cloudflare Workers® in 2017 with the goal of building the development platform that we wished we had. We want to enable developers to build great software while Cloudflare manages the overhead of configuring and maintaining the infrastructure. Workers is with you from the first line of code, to the first application, all the way to a globally scaled product.

We launched Cloudflare Workers® in 2017 with the goal of building the development platform that we wished we had. We want to enable developers to build great software while Cloudflare manages the overhead of configuring and maintaining the infrastructure. Workers is with you from the first line of code, to the first application, all the way to a globally scaled product. By making our Edge network programmable and providing servers in 200+ locations around the world, we offer you the power to execute on even the biggest ideas.

Behind the scenes at Cloudflare, we’ve been steadily working towards making development on the Edge even more powerful and flexible. Today, we are excited to announce the next phase of this with the launch of our new platform, Workers Unbound, without restrictive CPU limits in a private beta (sign up for details here).

What is Workers Unbound? How is it different from Cloudflare Workers?

Workers Unbound is like our classic Cloudflare Workers (now referred to as Workers Bundled), but for applications that need longer execution times. We are extending our CPU limits to allow customers to bring all of their workloads onto Workers, no matter how intensive. It eliminates the choice that developers often have to make, between running fast, simple work on the Edge or running heavy computation in a centralized cloud with unlimited resources.

This platform will unlock a new class of intensive applications with heavy computation burdens like image processing or complex algorithms. In fact, this is a highly requested feature that we’ve previously unlocked for a number of our enterprise customers, and are now in the process of making it widely available to the public.

cloudflare workers serverless serverless week product news

A “cold start” is the time it takes to load and execute a new copy of a serverless function for the first time. It’s a problem that’s both complicated to solve and costly to fix.

Today the Cloudflare Workers team is thrilled to announce the launch of Cron Triggers. Before now, Workers were triggered purely by incoming HTTP requests but starting today you’ll be able to set a scheduler to run your Worker on a timed interval.

Durable Objects provide a truly serverless approach to storage and state: consistent, low-latency, distributed, yet effortless to maintain and scale. They also enable coordination and real-time collaboration between clients.

HTMLRewriter for Cloudflare Workers now supports asynchronous handlers, allowing developers to prefetch assets or user-specific content from a remote service.

Today, we’re excited to announce support for Python, Scala, Kotlin, Reason and Dart. You can build applications on Cloudflare Workers using your favorite language starting today. We initially launched Cloudflare Workers with support for JavaScript and languages that compile to WebAssembly, such as Rust, C, and C++. Since then, Cloudflare and the community have improved the usability of Typescript on Workers. But we haven't talked much about the many other popular languages that compile to JavaScript. Today, we’re excited to announce support for Python, Scala, Kotlin, Reason and Dart.
