Cloudflare acquires Deno

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

i always wondered how they were making money

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

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.

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

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

Please be sure to read the post on Cloudflare's blog, it's not just fluff:

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.

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

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

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

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

> 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...

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.

Grats on the bag.

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

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

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.

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.

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

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.

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

One step towards a $25K github replacement?

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

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".

> 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 ...

</3

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.

Congrats Ry

RIP

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.

huhyyy

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

> Deno sells out

> 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.

What a shame. Guess me and the clankers will be maintaining a fork now

Sorry, but even factoring in that this acquisition carries over the existing customer base and goodwill, this is still **** (censored because I aim to stay polite). Deno is factually speaking a one to two week project at this point (proven by the numerous JS runtimes already on the market). I genuinely do not see how this makes any sense whatsoever. If Cloudflare was seeking to hire the team behind Deno they could have done it at a fraction of the price paid. This, naturally, assumes they did pay anything and I can't be bothered to look up the exact $$$ amounts.
