Cloudflare acquires Deno

Well this sucks. My blog is based on deno as I wasn't a fan of node.js at the time. I guess I'm gonna have to rewrite my blog engine.

Wow, so React Native and Deno both effectively have nails in their coffins. I wonder what's next.

Well this is very stupid. Why not move Deno to be based on workerd or something? or vice versa? throwing it away is such a waste.

What is it with everyone buying runtimes? — P.S. Deno always felt like it is going to be abandoned, you can't build your work on this much shaky ground...

Well this is fucking depressing.

So what's the story with JSR sticking around then? Does it already see meaningful use among people using Workers, or do they just really want an escape hatch in case we see more long-term issues with GitHub and NPM?

And does it at least mean the stdlib will see continued development?

Inevitable for a project like this when you take VC money, unfortunately.

Does this mean that celld is dead? No more open source durable objects?

Does Cloudflare already use Deno under the hood then? Like the Anthropic -> Bun aquisition

This is mostly to be expected.

After Deno did layoffs we saw a consistent decline in announcements and innovation.

Sad day, but unsurprising.

Wow. Just about to choose Deno for something. That not only makes me rethink Deno but ... rethink a lot of things ...

Fools... I downloaded it for free...

my recent comment [0]: was deno was the only other tech player building a proper serverless platform to bring Cloudflare workers in an open source manner.

will they continue that work ?

otherwise this is a proper acquisition. t

10 things I regret about Deno talk incoming

This is actually awesome news believe it or not. I'm excited b/c i think there's a lot of potential in the world w/ deno's team being on solid footing w/ cloudflare.

I know the runtime is in trouble, but i'm not as worried tbh b/c the principles deno championed are going to keep going.

anthropic + bun vs cloudflare + deno, could it be counter move for building from agent sandbox that runs on the edge?

Cloudflare really be buying up everything

Can we rename title to "Deno is winding down" ? It's not joining cloudflare. the people are

never used deno or paid much attention to it despite all the fancy marketing.

i always wondered how they were making money

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

> 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.

Extremely disappointing...

It's only OpenAI which doesn't have an in-house modern runtime

Grats on the bag.

Disappointing news to see it shut down, but maybe the writing was on the wall after they laid off some of their folks.

I've been using deno for years and built some nontrivial services in it. When deno added support for npm packages, the early days were pretty rough. I ran into lots of issues with packages and spent a lot of time reading random github issue threads. It's been pretty smooth sailing for the last year or so though.

At least I can use ai to help migrate off of deno.

Gotta say the fate of Deno has been pretty disappointing I had high hopes for it

Can't believe they bought out Vite and now Deno. All our toolchains are getting bought out by military contractors

is this a good or a bad news ?

I’m disappointed that they discontinue the Deno runtime. It really is a joy to use.

I think they ran out of money and joining Cloudflare was their only remaining option.

Congrats to the team! Sad to see deno go away, it’s a really great tool

Man, this year has been nothing but bad news for me. This is disappointing, and really makes me question what is the point if even open source is now this easily enshittified or "killed by [insert big tech co here]." I've spent years now using Deno nearly exclusively for new projects, and saw it as the most sane JS server runtime. This also makes me hesitant to use anything with Ryan Dahl's name on it ever again.

This is awesome. The Cloudflare platform is great; being able to run more of it locally is a definite plus.

Deno was a good idea in the Old World of software development before LLMs, and simply doesn’t make sense anymore.

Damn that is a shame. I liked pretty much everything about Deno. Especially great for scripting.

I'll probably move to Rust for scripting I reckon. It's not very mature but hopefully it won't be too much longer.

Fresh was also the best web framework I've used. Oh well.

R.I.P.

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

i guess bun won?

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".

sorry, but who even is still working on Deno? All my friends who used to work on Deno got fired

how about the IP? will the future open source project be DENO or will they have to come up with another permutation.

(I've trademarked ENDO , feel free to DM me for a license)

One step towards a $25K github replacement?

Announcing eDon, my rewrite of Deno in Rust!

Edit: Yes, but it's not named after me, which this fork fixes.

It's going to be the first JavaScript runtime to natively support Super Intelligence APIs.

I'm having an LLM replacing all occurrences of "ai" in every API with "si", in the hopes that OpenSI or SpaceXSI will acquihire me.

> The Deno team is joining Cloudflare to radically simplify self-hosting Workers and Durable Objects so developers can use the same primitives in more places.

Well, that's pretty big news actually.

Cloudflare is playing a big game ...

Holy shit, I used to work on the Workers Runtime Team and I'm surprised!

Congrats Ry

Honestly, this motion right here is the death of open source - the rug pull. I no longer can trust any open source project won't get bought up and sunsetted. I'm glad open tofu and valkey and Linux exist to serve as a counter example but this makes me sad.

can yall stop selling out to cloudflare? The continued consolidation of the internet/tech is wild.
