seems like simon only changed the readme and wasn't really involved in the project.

tests don't mean much if you are not an expert on the subject
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.
Why do you care?
It's a stranger from the Internet. Same as with any other software you're using. In particular, same as with any OSS tool you're using.
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?
Coding agents. They landed 918,000 lines of code in a single week: https://github.com/vercel-labs/scriptc/graphs/contributors?s...
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.
But it is indeed engineering, and that’s OK.
“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.
- 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.

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.
- 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
Note that “untyped dependency” means any code that says `any`.
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.
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 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:
static double sc_f_fib(double sc_l_n_0) { /* /private/tmp/fib.ts:1 */
double sc_t0 = sc_l_n_0;
double sc_t1 = 2.0;
bool sc_t2 = sc_t0 < sc_t1;
double sc_t3;
if (sc_t2) {
double sc_t4 = sc_l_n_0;
sc_t3 = sc_t4;
} else {
double sc_t5 = sc_l_n_0;
double sc_t6 = 1.0;
double sc_t7 = sc_t5 - sc_t6;
double sc_t8 = sc_f_fib(sc_t7);
double sc_t9 = sc_l_n_0;
double sc_t10 = 2.0;
double sc_t11 = sc_t9 - sc_t10;
double sc_t12 = sc_f_fib(sc_t11);
double sc_t13 = sc_t8 + sc_t12;
sc_t3 = sc_t13;
}
return sc_t3; /* /private/tmp/fib.ts:2 */
}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.
I had to do a triple take on this.
This phrase I think highlights the fundamental issue for a lot of folks that would otherwise consider adopting a project like this written by humans.
For a project like this, isn't it worth introducing a TS type for Ints? Since they are trying to leverage TypeScript anyway...
This part made me laugh out loud
1. TS only has a "number" type. But what type of number is it? This is doable safely via keywords (or known markers), or sometimes via analysis, but I couldn't find it in the README.
2. A compiler that works only on macOS?
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.
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.

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’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.
Deno doesn’t type-check external dependencies unless you ask.
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.
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.
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.
This is more equivalent to Go, with a single static native binary that does not include the whole Node runtime
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...
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.

whats the use case for this , make it hard to reverse engineer my node projects?
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.
Deno is building a less-wasteful Electron style framework for native desktop apps
I can't think of any serious company or project that would use this thing.
P.S: I just checked the contributors list, I have the utmost respect to them (notably simonw), but clearly this code is claude'ish but it is not among the contributor which makes it even more suspect.
