Cloudflare buys Deno to make Workers easier to run anywhere

Cloudflare has acquired Deno, the company behind a JavaScript and TypeScript runtime, and is bringing its entire team into the group building Workers. Workers lets developers run applications on Cloudflare’s network, while its Durable Objects feature keeps a piece of application logic and its data together, reducing the infrastructure developers must assemble to scale software. The deal centers on Deno’s newer celld project, an open-source version of that model: Cloudflare plans to merge it with its own runtime so the same approach is easier to run on a company’s own infrastructure, not just Cloudflare’s. That could make Cloudflare’s developer platform more portable, but it also winds down Deno’s separate products: its runtime will receive fixes for a year and Deno Deploy will close after six months, with paid customers offered migration to Workers.
