The Deno team joins Cloudflare to merge its celld runtime into Workers, and Deno Deploy will shut in six months

Cloudflare said on October 9 that the team behind Deno, the JavaScript runtime company led by Ryan Dahl, is joining it. The joint post by Dahl and Cloudflare's Kenton Varda says: “The Deno team is joining Cloudflare, and we're merging workerd and celld!” Workerd is Cloudflare's open-source Workers runtime; celld, released by Deno in August, is its self-hostable implementation of Workers.

Neither company's post gives terms. TechCrunch said the financial terms were not disclosed and called the deal an acquisition; Cloudflare's own post does not use that word.

Dahl's post on Deno's blog sets out what ends. “Deno Deploy will continue operating for six months before shutting down.” “We will support the Deno runtime for another year with monthly releases containing bug fixes and security updates.” After that, Deno's own work on the runtime ends. “JSR will continue operating, with its infrastructure moving to Cloudflare.”

Cloudflare's post says Ryan and a colleague it names only as Bert will lead an effort to make self-hosting workerd a fully supported option.
