Terms were not disclosed. The whole Deno team, including Ryan Dahl and co-founder Bert Belder, joins Cloudflare to fold celld, a Rust binary released in August that runs Workers and Durable Objects on a company's own servers, into the open-source workerd runtime. The Deno runtime stays open source but gets only bug and security fixes for one year before active development stops. The JSR package registry keeps running on Cloudflare infrastructure. Deno had raised about $26 million, including a $21 million Series A led by Sequoia. Dahl said the project had been pulled into chasing Node compatibility, while Cloudflare's Kenton Varda said self-hosting workerd will become a first-class supported option. Teams running agents or backends on Deno Deploy now have a migration deadline. The bigger signal is that edge platforms are racing to offer the same runtime in the cloud and on private hardware, a requirement that keeps surfacing as enterprises push agent workloads behind their own firewalls.
