Cloudflare announced October 9, 2026 that the entire Deno team is joining Cloudflare. Ryan Dahl and Bert Belder will lead merging celld into workerd to make self-hosting Workers and Durable Objects a first-class path for distributed applications.
Ryan Dahl created Node.js and later Deno; Kenton Varda created workerd and the Workers programming model. The post frames the join as combining Deno’s self-hosted runtime expertise with Cloudflare’s edge platform scale.
Operational details for Deno runtime, Deno Deploy, and JSR are covered in Deno’s companion announcement.
