Cloudflare acquired Deno (and will stop developing the Deno runtime in a year)
“Node’s inventor just joined Cloudflare. Deno has one year to live as a product.”
The Story
The Deno team is joining Cloudflare to merge celld with workerd and make the Workers/Durable Objects programming model easy to self-host. Deno runtime gets one more year of monthly security/bugfix releases, then Cloudflare stops developing it (it stays open source); Deno Deploy shuts down after six months with a Workers migration path. Dahl said Deno got trapped in Node compatibility gravity and wasn’t solving the bigger problem.
Why It Matters
The guy who created Node, then tried to replace Node, just sold the replacement to the company that wants JavaScript to be the operating system of the edge. Builder lore + the internet’s next default runtime.
