Deno is joining Cloudflare

Deno creator Ryan Dahl announced that the entire Deno team is joining Cloudflare, where it will merge its runtime and hosting work with the Workers and Durable Objects teams and push that programming model as the default way to build servers. Deno will remain open source and receive monthly bug-fix and security releases for another year before the company ends runtime development, Deno Deploy will keep running for six months with migration support for paying customers moving to Cloudflare Workers, and the JSR registry will stay online with its infrastructure moved to Cloudflare.
