Deno Is Joining Cloudflare

Deno's team has joined Cloudflare to further develop their innovative runtime and take it beyond the current limitations. The team's ambition extends beyond just providing a runtime; they aim to create a seamless experience for running applications, from compute and storage to communication. The Deno Deploy service has already been a step in this direction, simplifying the process of running applications. However, more work remains to be done to fully simplify the underlying complexity.

Kent Varda and the author of this story, while explaining the progression from Deno to Deno Deploy to celld, mention how this shift makes sense as Cloudflare combines their work with that of the Workers and Durable Objects teams. The aim is to make this programming model the default way of building servers, whether on Cloudflare's network or on the user's own infrastructure.

For those who have built on Deno, the authors express their gratitude for their contributions, code, problem reporting, and trust in their direction. They clarify that the move is significant for those who built their businesses on Deno, emphasizing the need for better abstractions, especially with the rise of AI.

Durable Objects, a feature brought together by Deno Deploy, is of particular interest to the authors. They highlight how this feature, with inexpensive, serverless execution, persistent state, WebSockets, and a high-level JavaScript interface, is perfect for building agent harnesses. This is why celld, the next step in Deno's evolution, focuses on Durable Objects.
