USL: One Script, 100+ Languages — Build It Once. Use It Everywhere.
Build once. Export everywhere. Logic to 100+ real programming languages with one click.
You've invented IR - eg take a look at egress targets in MLIR https://github.com/llvm/llvm-project/tree/main/mlir/lib/Targ...
Hey HN,
I built something I wish I had years ago.
USL (Universal Scripting Language) is a symbolic syntax system that lets you write logic once, and output that logic into 111+ real programming languages — Python, Rust, C++, JS, Java, Go, etc.
Upload a .usl file into the hosted app → choose any language(s) → download a .zip of the real code.
It supports:
Symbolic logic for print, assign, function, loop, if, etc.
Custom syntax templates for each language
A web app with multiselect UI + ZIP bundling
Gumroad option to support or unlock everything ($5)

I’d love your thoughts on:
How it could be more useful for devs/teachers
Any language you'd want added
Whether this belongs as a CLI tool, VS Code plugin, or playground next
Happy to answer anything or collab. Thanks for reading!
Hey, congrats on the launch. I'm interested in what use-case led you to create this? What problem does it solve?
I've had a little experience translating code between languages (ObjC/Swift, Javascript/Python), and it has been frustrating, not because of re-stating the logic, but due to different availability of libraries, different execution semantics (e.g. async/await), different type systems, etc.
Also, it looks like USL is a new language? Did you consider something like CEL instead (Common Expression Language, https://cel.dev/), which seems to be doing something similar for the expression of basic logic.
It's a new language. I haven't tried cel, but USL transpiles all of the logic--I'll keep working on it and make sure it works as you've mentioned.
I was curious to see if I could do something like this for fun. It currently works with 111 languages from the 40/50s-today.
I think the landing page would be a lot more convincing with more examples. Show some simple scripts and a few of the generated outputs so people can get an idea of what your app is capable of.
I find it impossible to take a $5 product seriously. It’s either a complete toy or the company will disappear inside of a year, or both. That isn’t a sustainable business model.
Edit: Aldo the very first line of the very first example has. Basic syntax error (missing. Terminal quote in string constant).
Can you post it so I can see please? Which languages did you try?
It's the first release--early bird pricing to raise funds for development.
I’m talking about literally the very first tab of the first example I. The link that was posted
It’s something like print(“foo)
Most languages are really just their standard library + ecosystem, go figure.
Heh, many languages have this inverse correlation between language features and the quality of their standard library. Zig for example has amazing language features, I wish that I could inline "orelse" or inline "catch" in Java, but I can't, and yet spinning up a cross-platform and asynchronous tcp server is infinitely easier in Java than in Zig. In fact, the more accurate correlation might be that the more annoying it is to write in a language, the more likely it is to have a thriving ecosystem, eg: Rust, Go, Javascript.
