That pushed the team toward Cloudflare Workers and its Durable Objects mechanism, and toward celld, which would let Workers-style machinery run on servers outside Cloudflare\u0026#39;s own.\u003c/p\u003e\u003cp\u003eCloudflare has already published the Workers runtime workerd as open source. The two teams now plan to fold celld\u0026#39;s technology into workerd, and Deno\u0026#39;s own development is the casualty. The runtime stays open source, but nobody has been named to continue it.\u003c/p\u003e","blueskyPost":"Cloudflare has acquired the company behind Deno and will end official development around October 2027.
