So unless someone else picks up development, Deno will no longer be supported.
This is a wild detail to just bury at the bottom. So many companies went all-in on Deno in recent years. Some even did major migrations off Node.js. Sucks for them I guess, but that's always the risk in chasing the shiny new thing over sticking to the old and dependable.
>So many companies went all-in on Deno in recent years.
Companies went all-in in a barely established niche player with 1/100 the traction, instead of sticking with Node, and even better an LTS Node, and are now surprised?
Do these runtimes have some value today? Sort of. But the cost of reimplementing them goes down, down, down. I made two bespoke JS runtimes within a year. Next year it will be even easier.
Deno/Bun see the picture better than I do, and they decided it was the right time for an acquihire.
However I now work with software that requires PQC resistance and node's native ML-KEM and ML-DSA abilities made me switch back. Also I'm not particularly an Anthropic fan so that was also a separate nail in its coffin for me.
I mean I used to do a lot of things I'm glad I don't have to anymore. I'm not a big fan of doing repetitive work just because I understand how to.
Node at least picked up --run, TS stripping support, .env loading, watch mode, and sqlite (plus some other things I'm probably forgetting) since Deno started so at least theres that.
I was really surprised that cloudflare was acquiring deno to be honest, I have written about this here before, Deno was always sort of dead to me due to how little they cared for compat of all kinds (nodejs, CJS, backwards). It was refreshing to see bun care a lot about it (well, now its on a different path in other ways).
Then I read that paragraph, and it made more sense that they're acquihiring + killing.
Fuck me! We’re going to have to start our migration as soon as possible. I knew we were in a precarious spot after the layoffs, but this is a truly sad outcome.
Right up until the day the founder gets bored and leaves Anthropic, or some middle manager does a reorg and the project isn't important to them anymore.
So are racial slurs or various things we can call you and your family. It’s never “just a word.”
Or we can go the other direction: if it’s “just a word” then it clearly means very little to you and a lot to somebody else, so why don’t you just be respectful and not use it? My parents don’t like cursing when I’m at their house, so I watch my mouth out of respect. I don’t demand that they make me agree with them beforehand. It’s just the right thing to do. Treat people with respect.
Why would you care if a random stranger on the internet says a word that you have deemed a no-no? Especially when the word has nothing to do with you - that looks more like looking for things to be offended by.
These people are absolutely determined to tell everyone what to do. I’m not sure why they think anyone will listen, especially given the utterly unhinged nature of their core values.
“Go back to Reddit” is the exact kind of comment the guidelines here explicitly ask people not to make. Your account isn’t that old by the way, so maybe don’t get on a high horse about forum culture.
Whining about “PC culture” is also pretty stale if you’re going to accuse this guy of living like it’s 2020. Though I don’t see what’s so offensive about telling people to treat each other with respect and to not use clearly harmful, othering language that trivializes mental health issues.
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.
Insane, I'm deeply saddened and embittered, I don't want to go back to NodeJS and I don't find any advantage in Bun. I guess this is my sign to just get off of JavaScript entirely.
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.

Bad news, sorry, the article says:

Sounds like Celld will live on within workerd, Deno is over.
> I’m happy if this means Deno is able to get a second impulse.
From TFA: 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.
The fact that Deno development is being suspended doesn't mean the community can't step in. The Deno runtime is licensed under MIT. Such forks might be impulse to grow even further.
I think the biggest thing Cloudflare needs to buy is some sort of Postgres-database service. They've already cornered the market for everything front-end/serverless
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.
A lot of the comments are on sunsetting Deno, but the more interesting part is merging the celld model into workerd.
I've been following celld since it was announced. Bootstrapping both durability and coordination off object storage simplifies so many things for self-hosting. (Yes, ironic that self-hosting has a cloud dependency, but in this case I think justified because S3 has become a widely supported protocol that you can run yourself too).
Will be curious to see the details on exactly how that model makes it into workerd.
>A lot of the comments are on sunsetting Deno, but the more interesting part is merging the celld model into workerd.
I think people are focusing on it because if you've built your business on Deno, then the "Deno will have no support in 13 months time" is a bit of an existential risk, and will be a huge time-sink for your team. So it's far more interesting to most of the people reading this page on HN, because HN is full of people who are first-adopters.
I have no idea anymore what is happening, and none of the blogposts seem to explain that either. So, if I am to start a new JS or TypeScript project or whatever, what should I choose and why? One runtime used a lot of tokens to rewrite Zig project, one was already Rust, one bought, one rewritten in Go, what is going on?
I don't choose TS/JS for new projects anymore unless they're browser based. If you need to be in JS land for whatever reason, deploy with Node but do local package management/testing with Bun, because it's way faster for those and you can migrate off without too much pain if it ever becomes problematic.
You should choose Node.js unless you have a good reason to use something else. This is what everyone uses, and it is used widely enough that it's in the same position as Java, i.e. it will be supported forever.
Also the other runtimes only offer incremental improvements.
Regarding the blogposts, you don't read a lot about Node.js because it is mature software and there isn't a lot of drama or new things to talk about.
One was not rewritten in Go. Typescript rewrote its compiler in Go, but that doesn't affect which runtime you use for the resulting Javascript code. Moreover this isn't producing a fork in Typescript as it is a replacement for the previous compiler, at least once they're done with it. The JS runtime forks and churn are not related to Typescript per se.
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.
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.
It's not the death of open source. It will probably be the death of small company open source. Either 100% community/non profit or 100% big corporation and users check corporate alignment with project goals.
Especially with LLMs automating all sorts of code and operational aspects, we could do Tcl/Lua type whitelist sandboxes where the application can only call a limited set of functions.
I think it makes more sense to use the kernel‘s’s sandboxing utilities (like seccomp, SELinux, namespaces, prctl and eBPF) than to rely on the process to try to isolate itself purely in userspace which will always have holes.
I mean, sure, but this doesn't preclude CF from keeping a few people around who can work on the runtime while everyone else does... whatever CF wants them to do.
They don't even need to be the long term stewards either. Spend some time setting up a proper governance structure for Deno, hand it off, and then pay some maintainers to continue their existing effort.
At least how it's stated in the post, it really feels like an "ah good luck everyone, I'm out!" sorta deal, which seriously sucks for everyone who really believed in Deno.
> 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.
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. 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".
No if that were true they wouldn't be stopping development of Deno, which as it stands sits in the best position for codemode given it's granular sandboxing.
> Deno people probably just want a paycheck after they spent years seeking glory and money on something that other people used but didn't pay them a cent for.
My take: Opensource-Infrastructure-as-startup-but-also-charity is a thing that is going to die along with ZIRP. I don't know why VCs ever sniffed around things like this in the first place. The younger generation that followed this business model with liberal "take my stuff" licenses and sneered at GPL etc are learning the hard way that making a nice cool thing and getting noticed is not going to earn you a good living. (And other people will make millions off your passionate work.)
No people on the Boards of both companies? Sorry for being cynical. Seen so much funny stuff in this industry. Good for Deno. Better choice given the talent behind it than Bun, IMHO.
So what am I supposed to do, just congratulate them and avoid any critical thought so as not to get downvoted into negative territory on my first day commenting on HM after 5 years of staying away for this exact reason?
> 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.
I'd guess Deno failed because of the original decision of not supporting node_modules, instead went with a different way of handling dependencies. Else the native typescript support would most likely had pushed them to bigger success past nodejs.
Though nodejs was even then quite solid in it's position, so maybe it would not have made a difference.
Deno wasn't doing well and was repeatedly outperformed in downloads and raw performance when Bun was written in Zig, and even before Bun got acquired by Anthropic.
My point is, even if Bun stayed on Zig, Deno still struggled to compete regardless of the language used.
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.
I do appreciate that it's not explicitly anti-competitive, but as a biochemist who spent a lot of time thinking about living systems, I am a bit concerned about a budding ecology that has perhaps collapsed <3
But I do have a strangely high trust in the individuals involved (you, Ryan, Sunil, others), even though I am a bit perplexed by CloudFlare's incentives or economics
Which is to say: I am choosing to be optimistic :)
Caveat, am commenting before reading, mind you -- just my general reaction to mergers in a world that never cleaves :)
EDIT: though this has also probably deflated a lot of the good-faith conversations I was having with gov-adjacent Europeans about celld being a boon for the moment of heightened European sovereignty, where EU data residency isn't necessarily considered enough distance anymore.
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...
So unless someone else picks up development, Deno will no longer be supported.
Companies went all-in in a barely established niche player with 1/100 the traction, instead of sticking with Node, and even better an LTS Node, and are now surprised?
Do they also do their front-end in Dart?
This is actually a good decision though.
Deno/Bun see the picture better than I do, and they decided it was the right time for an acquihire.
They should hire a few devs to develop it then.
For my projects, I am used to maintaining package manager configuration, bundlers, linters etc.
So I never had much interest in looking into benefits of Deno or bun.
However I now work with software that requires PQC resistance and node's native ML-KEM and ML-DSA abilities made me switch back. Also I'm not particularly an Anthropic fan so that was also a separate nail in its coffin for me.
Node at least picked up --run, TS stripping support, .env loading, watch mode, and sqlite (plus some other things I'm probably forgetting) since Deno started so at least theres that.
I don't. What do you mean?
Then I read that paragraph, and it made more sense that they're acquihiring + killing.
It's an acquihire. They hired the people behind Deno
unless cloudflare's CEO is a friend of cloudflare people, so just want to financially them bail out...
...why acquire and kill? cloudflare can have more outreach and reputation by keeping deno alive
I'm sure they'll have a migration path to the cloudflare platform in 12 month.
From what is likely going to happen is that Deno will be donated to the Linux Foundation to avoid this.
Or we can go the other direction: if it’s “just a word” then it clearly means very little to you and a lot to somebody else, so why don’t you just be respectful and not use it? My parents don’t like cursing when I’m at their house, so I watch my mouth out of respect. I don’t demand that they make me agree with them beforehand. It’s just the right thing to do.

From TFA: 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.
Finally, the next step of forking Node is up for grabs:
Node > Deno > Done (anyone?)
I also wish they expanded jurisdiction more. I worked at companies that couldn't use Cloudflare because of specific location requirements in contracts
If they bought Neon that'd be a coup.
edit: my reaction was too soon, it seems like they will be explicitly working on making workerd an open source self hostable runtime
will they continue that work ?

I guess I can say that this means Deno won't ever have a much needed Python 3 moment.

They would rather have Deno pursue an acquisition instead of shutting down and losing their investment.
The only questionable detail about this announcement is it was for an undisclosed amount. Make of that what you will.
So Deno is going to be unsupported and will no longer be maintained and will be discontinued.
