Claude-directed code by someone being conscientious and getting involved in the important decisions is going to be better than a whole swathe of existing open-source that was hand-written.
“Better”, maybe or maybe not. But there’s an underlying truth here. If you’ve ever LOOKED at the open source libs you use, some of them are very very rough.
Going in to a project hoping to make a change and seeing no tests and spaghetti used to be soul crushing. These days I’d have Claude go refactor and add tests and make pull requests for me to look at to fix it.
Maybe if it's a business level tool made in house with claude vs contracted to a software house in India. Never for a compiler, who even is that person?
>But apparently random HN commenters can now overrule an AI ML expert because the code "looks Claude-ish"!
And let’s imagine if LLM bots could do that as well, without any human caring to type the actual messages, just orchestrating the bot fleet. What trust could be we put in such a brainless peace of publications?
Porforr<https://porffor.dev> has been working towards the same goal for a while. The creator, CanadaHonk<https://honk.foo>, is extremely talented and the project still only passes ~68% of Test262. I'm more than a little suspicious of how Vercel has made so much progress so fast, unless I'm misunderstanding the scope of this project.
Christ. Imagine if bridges, skyscrapers, dams, cars, airplanes were designed and built like that.
I vibeslopped thousands of pages of blueprints, nobody reviewed them, but another team of digital monkeys with the intellect of an ant have already built the bridge, and it seems to not have collapsed yet, so we're already directing traffic there.
I can't imagine actual engineers feeling anything but deepest contempt for this industry.
"Actual engineers" don't really care about software engineering, much less a strong emotion at all like the "deepest contempt" and many of them already vibe code today for their work anyway.
Oh no, we do, because the software world has been abusing what engineering means for decades, in order to inflate job titles. Most people are programmers, not software engineers, and that's OK.
> already built the bridge, and it seems to not have collapsed yet, so we're already directing traffic there.
“Actual” engineering went through a phase where bridges and other structures did collapse due to structural flaws - it’s not like they magically figured out ahead of time how to avoid that.
Now, they can build structures that are some specified tolerance away from collapsing, but that’s only the case because the edges of what was possible were explored.
That makes sense. It also seems like this uses a lot more dependencies and tiers of compilation whereas Porforr is trying to do everything from scratch.
I don't actually see any dependencies other than node and typescript (and the optional quickjs package) (maybe they inlined dependencies? But the package.json files don't indicate any npm dependencies)
Putting aside the whole “team of professionals putting out a product vs solo dev fine tuning their opus” of it all:
Can you clarify what about the architecture is ‘idiotic’? Not trying to catch you or demand a defense, just looking for a vague description. I don’t even know how to start examining the architecture of something like this.
As far as I can tell they pull in QuickJS (actually quickjs-ng) only in the case where the program has untyped dependencies that still need to be run by an interpreter - and they chose that library because it's pretty small (620KB). Did I miss something, are they using it outside of that purpose?
They won't have untyped dependencies for situations where someone used Scriptc as a way to build a fast binary executable for some custom-written TypeScript, which was the first use-case that came to mind for me.
Being able to build small, fast binaries without writing them in C or Rust - if you're already fluent in TypeScript - seems like a valuable capability.
Yes, being able to build small and fast binaries in TS would be a valuable capability, which is why basically all of us who work in this space have thought of this idea and rejected it after going deep on it. This isn’t a new idea.
CanadaHonk has gotten further than the rest of us. It’s surprising and impressive.
You’re only replying to the quickjs issue I raised, but it’s not the only issue. Their approach to numbers is broken. Their approach to measurement is broken. The quickjs thing raises another red flag: it suggests to me that they are using reference counting, not GC. That’s guaranteed to make them too slow to be useful. (If they weren’t using RC, then they’d have a hard time on the boundary to quickjs.)
As to the `any` issue, let me explain it in a way you’ll appreciate. I asked Claude how likely it is that TS code uses any, and it found:
- 79.5% of TS repos use any explicitly. So, about 4/5 chance that newly written dep-free TS code will use it.
- the explicit any type is about as common as Boolean and void.
- a third of inferred types are any. That’s huge.
So, if you don’t believe me, then at least believe Claude: any is a super common type, so they will be falling off into quickjs a lot.
Oh, and in case it isn’t clear, quickjs-ng is no better than quickjs. They’re the same thing for the purpose of perf
If you’re writing Typescript with zero dependencies and trying to target native I feel like it makes more sense to write it in a different language like Rust or Go. The main reason for this I think is getting cheap perf wins by running existing code natively.
Personally i can kind of see a use case here. I've shipped some simple server side packages as a "compiled" Node single executable written in TS, but you're stuck with the big overhead of Node.
I've just been teaching myself Go, also a single binary but without the overhead. But in Go i miss the expressiveness of the TS type system sometimes.
Devil's advocate - this is for the backend. You get to control your dependencies there, and I'd say Vercel controls its own stack, so they can replace deps as they go by submitting patches/slopforking projects to remove incompatible features.
this is enough to keep them on the first page of HN and similar services. Its a growth strategy: invest tokens, build some "nice" project nobody wants, get some reach through publishment. Rinse and repeat.
Heads up, in 12 months from now, 90% of open source projects will be vibecoded, without actual users - only looking "interesting" (if not already?).
Its easy to vibe code a full blown compiler these days, the question is: will it be maintained? A catchy title is not enough to get sticky users, long term maintenance, community around the project is (or at least used to be).
Having said that, the only viable reason for these kind of projects I see is getting attention for a moment, boosting reach of Vercel logo across the web and then disappearing (or stop development).
If Vercel would think seriously about this project: they would show skin in the game - for example implement it as their own experimental runtime.
One of the strengths of TypeScript besides its expressiveness is that it's compatible with the massive npm ecosystem. Most packages only ship untyped JavaScript with type declarations defining the interface,[0] so realistically you'd still need a JavaScript engine if you use any packages.
But if you're starting from scratch and know you won't be using any npm packages, you might as well use AssemblyScript.[2]
[0]: Publishing packages in TypeScript is explicitly discouraged by Node[1]. TypeScript isn't backwards compatible even in minor releases, and its compiler settings aren't portable for packages.
> so realistically you'd still need a JavaScript engine if you use any packages.
Looks like Scriptc's solution to that problem is that it can optionally bundle a 620KB quickjs-ng JavaScript engine if you have dependencies that need to be executed that way.
Those are good reasons to publish untyped libraries as a rule, sure. But the contention that those reasons outweigh the value of types kinda boggles the mind, ngl!
Publishing a lib as JS with .d.ts type files gives you JS compatibility and TS types for using the lib, but no TS source so no types inside.
I’ve seen people want to publish TS libs but there are issues: TS will type check the libs as well as your project. You can’t tell it to stop just because it’s going inside node modules. And the app may have tighter settings than the library and you will get type errors if your configs were setup differently. It would be interesting to standardize publishing real typescript libs but I haven’t seen it. Maybe deno tried? I haven’t looked.
When publishing on jsr.io, you upload the TypeScript, and if using Deno, you also download TypeScript (with import statements rewritten.) Having nearly the original source code is better for debugging.
Deno doesn’t type-check external dependencies unless you ask.
This seems like a fully-llm-architected project: "Make a compiler that converts typescript to native code". It might work as llms get better, but if the generated files are thousands of lines long, they can never be maintained by a human. This is a dead end.
I've been working on something very similar (was previously on HN) for the last 9 months, almost full time. I went through the code - all I can say is that the last 10% is 99% of the work.
It's nice they acknowledge and confirm the need for small, fast native executables.
Having followed the story for this in Java over the decades I'm skeptical about the practicality.
GCJ existed in the 90s and the technology was good, but there was no ecosystem support.
After many small steps between GraalVM Native finally tackled the problem more holistically and the ecosystem followed. All the major libraries and frameworks put effort into being GraalVM compatible.
And, still it's a major pain to make even simple existing applications run flawlessly natively.
I'm glad something like scriptc exists but I'm afraid until this is of practical use it will be s long thorny way.
I desperately want to see some of these projects used in production by the companies or people making them, at best it might prove that it isn't just a sloppy publicity stunt
Funny to see vercel is loosing all credibility under the influence of AI.
Never liked their products anyway, so I believe it's a net positive for the industry :)
This is like putting lipstick on a pig. Give me an AI written README or tests but actually thoughtful codebase over human written readme but aislop code any day of the month
I've heard stories like this before, how one or a few people miraculously coded up an alternative to Node.js. But can you name even one that actually works properly in production? Not a single one.
Take Bun, for example. Nobody is actually running it in production as a runtime. Why? Memory leaks and a whole bunch of other issues. I've personally tried it multiple times, and something always breaks. Come on, it's just not that simple.
Sure, you can build something that has similar interfaces and even works to some degree. But making a production-ready solution is a completely different level of complexity. There's that well-known chart where the first 90% of implementation happens almost instantly, and the remaining 10% takes forever to polish out all the rough edges.
On one hand, I really like the idea, and I've always wondered why TypeScript doesn't compile to native code. On the other hand, I'm quite skeptical that Vercel can actually pull this off. I'd be happy to be proven wrong, but I have very little faith in it.
Either way, good luck to them, but honestly, even if they succeed, I probably won't use it. Knowing their track record with vendor lock-in and Next.js, where they do everything possible to push you onto Vercel Cloud — no thanks.
We are increasingly using a subset of typescript in our backend so as to be amenable to a tool, in the long run, which can convert the ts subset to rust source code.
This project will enable an alternative of that vision earlier - except of course without the parallelism.
Also I am curious as to whether this will compile to a static lib which can be linked to an existing cpp app to be run on android/ios targets. In theory it should be able to. The docs mention ffi, but I didn't dig deep.
A lot of people are trying this now with AI, a native TypeScript compiler, for example https://github.com/PerryTS/pry. It's a compelling value proposition, TypeScript is already well typed and barring a few cases it can be turned into machine code without a JS runtime.
Agreed. Along those same lines, their startup time claim "faster than go", gives me concern because the slowest part of go startup is the various GC-related initializations. If they are doing GC, then you would assume their times would be broadly similar.
This is one of the things that is tiring me out the most. Previously people could have these "ohh shiny" ideas and would lose steam before they could be implemented, especially in areas they're clueless about.
Now people can have these ideas, slop together an awful solution that works at a surface level, maybe, but will never really go places because the foundation is slopped with no party involved actually capable of thinking thing through. But hey we launched something so let's make lots of noise! Oh look, a banana ... Sorry, what were we talking about?
There's an engineer on a team at work that I routinely engage with who slops together stuff so fast his team is basically exhausted all the time. They're stuck picking up a whole stream of pieces of crap because the engineer is incapable of actually doing the hard work of getting things to production because there's more "ohh, shiny" stuff they can spend tokens on, and their leadership aren't stepping in because it all looks terribly productive (it really isn't)
I have forked Fabrice Bellards QuickJS and extended it heavily to adopt anti-npm/node stance.
all of the essential standard lib and top npm packages will be built natively in C17 with every build and minor release focred through CPU, IO and memory profiling.
Currently it supports MacOS and Linux, FreeBSD and Windows in future.
Either it is only accepting a subset of TypeScript, or it is still interpreting the parts that don't have enough types. Given other comments here it sounds like the later.
What it can actually compile is a subset of well-behaved typescript. For anything else it bails out and asks you to ship a JS engine (albeit, not NodeJS) again.
another use case is getting standalone self-contained binaries which are easier to ship.
other projects like claude code use something like `bun build --compile`[^1] for that, which instead of producing a small native binary just bundle the JS runtime into the executable.
Don’t see how compiling Typescript changes how little Electron cares about the host OS in terms of UI and how it just ships Chromium in order to show any UI at all

It's coming from Vercel, what do you expect?
I don't actually see any dependencies other than node and typescript (and the optional quickjs package) (maybe they inlined dependencies? But the package.json files don't indicate any npm dependencies)
That explains why:
- the architecture is idiotic.
- they have zero credible perf numbers.
I plan to benchmark it using generally accepted methods.
Porffor makes careful trade offs that make sense and is benchmarked in a way that I can believe.
(Source: I make dynamic languages fast for a living)

Can you clarify what about the architecture is ‘idiotic’? Not trying to catch you or demand a defense, just looking for a vague description. I don’t even know how to start examining the architecture of something like this.
Yeah
- using quickjs at all in a thing that needs perf. Quickjs is hilariously slow. Midwits use it because it has “quick” in the name.
- using floats for numbers and deferring int optimizations for later. Inferring ints is like half the problem of fast JS.
- rejecting inadequately annotated or too dynamic code without a whole heck of a lot of self-reflection about how unlikely that is to work out.
The observation that languages that are even slightly dynamic need dynamic JIT opts is very old; folks figured that out in the 80s.
This project reeks of weapons grade AI psychosis

They will have untyped dependencies. That’s how the TS/JS ecosystem works.

If I was using this project for something I'd expect to write custom TypeScript for it.
The floats rather than integers thing does look bad though. I tried compiling their fibonacci example to C (--backend c) and got this:

I had to do a triple take on this.
I think more human effort is going into defending this project then what was put into the project itself haha.
There is always AssemblyScript
So like less than 1% of the time? What part of the JS ecosystem doesn’t depend on a mountain of untyped dependencies?

Looks like Scriptc's solution to that problem is that it can optionally bundle a 620KB quickjs-ng JavaScript engine if you have dependencies that need to be executed that way.
I would use it for a focused command-line tool that needs to share code with a larger TypeScript project, not for code with a lot of dependencies.
Those are good reasons to publish untyped libraries as a rule, sure. But the contention that those reasons outweigh the value of types kinda boggles the mind, ngl!

Anyone serious would be paying for Excelsior JET, BEA JRockit, or the myriad of other commercial JDKs wihth AOT tooling.
In fact most likely one reasons why Excelsior is not more, is that now GraalVM and OpenJ9 exist as free bear.
PTC and Aicas still have it good, because few care about their embedded and real time customers.

We are increasingly using a subset of typescript in our backend so as to be amenable to a tool, in the long run, which can convert the ts subset to rust source code.
This project will enable an alternative of that vision earlier - except of course without the parallelism.
Also I am curious as to whether this will compile to a static lib which can be linked to an existing cpp app to be run on android/ios targets. In theory it should be able to. The docs mention ffi, but I didn't dig deep.
A lot of people are trying this now with AI, a native TypeScript compiler, for example https://github.com/PerryTS/pry. It's a compelling value proposition, TypeScript is already well typed and barring a few cases it can be turned into machine code without a JS runtime.
Does this mean I can turn my JS-based backend into single executable and easily ship it, like in Go?
Recent versions of Node can package a backend into a single binary already, it'll just be 100MB+ and embed the whole Node runtime.
This is more equivalent to Go, with a single static native binary that does not include the whole Node runtime
178kb?! What are you putting in there, a JVM?
You're 2-3 orders of magnitude off for a JVM
Agreed. Along those same lines, their startup time claim "faster than go", gives me concern because the slowest part of go startup is the various GC-related initializations. If they are doing GC, then you would assume their times would be broadly similar.
Hasn't quickjs and GraalVM been able to do this for a while now?
Also, does "Linux and Windows binaries build by cross-compilation" mean that you can't run it on non-MacOS? If so, that's pretty lame...
another vercel labs thing that's been slopped together, hyped up on twitter and then left to be forgotten about in a few months time.
This is one of the things that is tiring me out the most. Previously people could have these "ohh shiny" ideas and would lose steam before they could be implemented, especially in areas they're clueless about.
Now people can have these ideas, slop together an awful solution that works at a surface level, maybe, but will never really go places because the foundation is slopped with no party involved actually capable of thinking thing through. But hey we launched something so let's make lots of noise! Oh look, a banana ... Sorry, what were we talking about?
There's an engineer on a team at work that I routinely engage with who slops together stuff so fast his team is basically exhausted all the time. They're stuck picking up a whole stream of pieces of crap because the engineer is incapable of actually doing the hard work of getting things to production because there's more "ohh, shiny" stuff they can spend tokens on, and their leadership aren't stepping in because it all looks terribly productive (it really isn't)
Does it compiles to C? Wasm? I couldn’t find it the readme slop
I like the idea.
finally someone did this
Whatever happened with their new programming language for agents? I expect this will follow the same path.
Shameless plug but worth reading :
I have forked Fabrice Bellards QuickJS and extended it heavily to adopt anti-npm/node stance.
all of the essential standard lib and top npm packages will be built natively in C17 with every build and minor release focred through CPU, IO and memory profiling.
Currently it supports MacOS and Linux, FreeBSD and Windows in future.

how can you compile it if javascript is a valid subset of typescript? confused.
Either it is only accepting a subset of TypeScript, or it is still interpreting the parts that don't have enough types. Given other comments here it sounds like the later.
No idea about this project, but it is very possible to compile a dynamically typed language, without large VM/runtime. See Common Lisp, Julia
Both, basically. Default is the subset, but you can enable an interpreter
What it can actually compile is a subset of well-behaved typescript. For anything else it bails out and asks you to ship a JS engine (albeit, not NodeJS) again.
this is interesting , so i can turn electron into a native app now?
whats the use case for this , make it hard to reverse engineer my node projects?
Still need the entire browser DOM, APIs, layout, renderers, etc outside of JS.
Some of us don’t like Spotify, Slack, Discord, and a simple notes app taking 1-2GB of RAM each..
another use case is getting standalone self-contained binaries which are easier to ship.
other projects like claude code use something like `bun build --compile`[^1] for that, which instead of producing a small native binary just bundle the JS runtime into the executable.

This is a really important question. If true, it could end a lot of Electron wastefulness.
Don’t see how compiling Typescript changes how little Electron cares about the host OS in terms of UI and how it just ships Chromium in order to show any UI at all
Nothing more horrible than apps that "care about the host OS in terms of UI", thus looking different on every type of device I have to use for work.
Im 99% certain it cannot. This seems better suited to server side projects.
