Cloudflare acquires software startup Deno to strengthen Workers
Deno was co-founded by Node.js creator Ryan Dahl and had raised US$26 million.
Cloudflare has announced that it will be taking on the entire Deno team to build a new platform called celld of Cloudflare. This platform is designed to allow distributed applications to scale without requiring the infrastructure typically set up by each team. The announcement was made by Ryan Dahl, co-creator of Node.js and founder of Deno, on October 9, 2026.
Deno Deploy, the current service provided by Deno, will continue to operate for six more months and then will be shut down. During this period, paying customers will be migrated to Cloudflare Workers. The Deno runtime will receive monthly security patches for one year, after which Cloudflare will stop developing it and the project will become open-source for the community to continue. JSR, Deno's package registry, will continue to operate but its infrastructure will be moved to Cloudflare's servers.
Rusty_v8, the Rust bindings on top of Chrome's V8 engine used internally by Deno, will continue to be maintained and integrated into Cloudflare's workerd runtime. The new platform, celld of Cloudflare, will be built using Workers programming model, combining serverless execution, persistent state, and real-time communication. This allows an application to scale without requiring additional infrastructure set up by each team.
