Deno, the modern runtime for JavaScript and TypeScript, is joining Cloudflare. The announcement was made on the official Deno blog on October 9, 2026, by Ryan Dahl, the creator of Deno and Node.js. The entire Deno team will move to Cloudflare to work on the company's developer platform, specifically the Workers and Durable Objects teams.
The move marks a major consolidation in the JavaScript and edge computing ecosystem. Deno has been a popular alternative to Node.js since its launch, known for its focus on security, simplicity, and modern tooling. Now, its future development will be folded into Cloudflare's infrastructure, a clear signal that the company wants to become the default platform for building server-side JavaScript applications.
Why Deno is joining Cloudflare
According to the blog post, the decision comes after years of working to simplify server software development. The Deno team explored how modules could be distributed, what security guarantees a runtime could offer, and how to make applications easy to deploy. They also built Deno Deploy, a serverless hosting service for JavaScript projects, and more recently celld, a project built on Cloudflare's Workers programming model.
The post explains that building and operating Deno Deploy revealed how much complexity remained under the hood. This led the team to focus on celld, which aims to make distributed applications simple to operate from the start. By joining Cloudflare, the Deno team will combine their efforts with the Workers and Durable Objects teams to make this programming model the default way to build servers.
What happens to Deno and Deno Deploy
The blog post states clearly that future development work will go into the shared Cloudflare platform rather than continuing to develop a separate runtime and hosting service. This means Deno as a standalone product will no longer receive the same level of active development from the core team.
