I’m happy if this means Deno is able to get a second impulse. I use Deno daily and while it’s true that it’s in this weird position where it’s not sexy like bun or enterprise-y like node, it has a great developer experience. a no-surprises runtime that does a lot of interesting things the right way (like compile to desktop to a browser-less webgpu runtime), the vscode extension is flawless and overall the perfect balance of batteries included without bloat. of course i’m only talking about deno, the technology not deno, the cloud service.

> We will support the Deno runtime for another year with monthly releases containing bug fixes and security updates. After that year we will end our development of the Deno runtime. Deno will remain open source, and we welcome others who want to continue its development. So unless someone else picks up development, Deno will no longer be supported.

If this was done to kill celld as a runtime that would be unfortunate. edit: my reaction was too soon, it seems like they will be explicitly working on making workerd an open source self hostable runtime

The Cloudflare side is also worth a read: https://blog.cloudflare.com/deno-joins-cloudflare/

I'm very surprised they are not running with the runtime. That seemed like Deno's secret sauce? The rest of it is very aligned with Cloudflare already, deploy, kv, workers, etc seems like the lower hanging fruit.

As a bystander, I'm excited by this. I don't know what it'll be, but I have a sense some interesting, powerful, and secure new ways of shipping code could come from this marriage...

> We will support the Deno runtime for another year with monthly releases containing bug fixes and security updates. After that year we will end our development of the Deno runtime. Deno will remain open source, and we welcome others who want to continue its development. So Deno is going to be unsupported and will no longer be maintained and will be discontinued. It looks like "written in Rust" is not enough for a selling point and lost out to the fierce competition against Bun.

Congrats on the exit :) Finally, the next step of forking Node is up for grabs: Node > Deno > Done (anyone?)

No idea why CF wouldn't just have them to continue working on Deno indefinitely...

Please be sure to read the post on Cloudflare's blog, it's not just fluff: https://blog.cloudflare.com/deno-joins-cloudflare/ TL;DR: Ryan and co. will be merging celld with workerd to create one first-class open source self-hostable runtime for Workers and Durable Objects. In the post I explain in the post why, contrary to what you might think, this is good business for Cloudflare and we're very excited about it.

So both major (and the only meaningful) possible Node alternatives have been absorbed into proprietary monoliths in the last year. We all know how well the Joyent years went, RIP to open source innovation at this point.

Congrats Ry

I feel it leaves a bitter flavor how Ryan Dahl pushed so hard for Deno and Deno Deploy for years, just to let them die within 1 year and 6 months respectively. Thankfully I don't have any codebases that heavily use Deno features, otherwise this would be a steep curve now.

> Deno sells out

Congrats. But also terrible news for the ecosystem; this project was a bit doomed from the start, and they acknowledge it multiple times (implicitly), but nice to have competition, I guess. Ultimately I only trust Node.js to succeed. Bun being too deep into "shipping anything that increases usage".

is this Cloudflare signalling they're going to hard pivot to being an AI company?

Disappointing. Everything I want to express about this is impolite. I guess I can say that this means Deno won't ever have a much needed Python 3 moment.

really wondering what role celld played in the negotiations
