Framework
Cloudflare's open-source JavaScript and WebAssembly server runtime, built on V8 isolates, which powers Cloudflare Workers and can be self-hosted.
Cloudflare is acquiring the Deno team, with one year of bug and security fixes committed for the runtime. Anyone building on Deno now has to choose between migrating and backing a community fork.
Reality
Deno's entire team is joining Cloudflare and taking celld, its open-source implementation of Workers and Durable Objects, along with it. For teams on Workers, the code they would use to leave now comes from the company they would be leaving.

Deno Deploy shuts down around April 2027 under Ryan Dahl's plan to move the whole Deno team to Cloudflare, a dev.to migration guide reports. Hosted apps must move by then; teams self-hosting Deno get a longer deadline set by the end of security releases.
Reality
Cloudflare made Python Workers generally available on September 21, moving binding type conversion into the runtime and adding ASGI and WSGI connectors for FastAPI, Django and Flask. Outbound TCP still goes through JavaScript's connect().

A week building an image SaaS on Cloudflare Workers produced nine failures. In the five shown in code, two come from the TanStack Start plugin's build behaviour and three from React timing and captcha logic that follow the code anywhere.
Reality
The Node.js API surface and the larger bundle ceiling arrive by default, but the resolution fixes that unblock ported apps only apply to Workers that opt in, and they bite hardest once your bundler stops flattening imports.

Cloudflare has open-sourced the internal platform it built after staff began demanding admin tokens for homemade AI apps. The design bet is on capability grants, not on the model.
