Cloudflare brings in the Deno team so that Workers and Durable Objects can run on your own infrastructure
Ryan Dahl, creator of Node.js and Deno, joins Cloudflare with his team; they will merge celld and workerd so that self-hosting Workers becomes a first-class supported option.
If you ruled out Cloudflare Workers for fear of vendor lock-in, this move changes the calculation: the stated goal is that the same application, Durable Objects included, can run on your servers or on another cloud. It is still a promise, so do not migrate because of it; but in your next architecture review, ask for a trial of celld to gauge the real cost of exit.
