What is a In-browser Data Engine, mastering WASM, and near-native workers - AMA about Datastripes

Hey Product Hunt 👋

I’m Vincenzo, and over the past few months I’ve been heads-down building something I wasn’t even sure was possible: a full-featured data engine, with drag & drop analytics, visual dataflows, machine learning, and real-time smart insights that runs 100% in your browser.

No servers. No backend. No installations.

It’s called Datastripes, and it’s my answer to:

Why does working with data still feel like you need a degree in engineering?

So, why in-browser? Because if you want something alive, something you can actually see flowing, and something that’s private and secure by design (everything runs locally), this is the way.

But getting this to work client-side wasn’t easy:

Processing big data in memory without frying your laptop

Building a modular compute graph with real-time feedback, all in JS

Running regressions, t-tests, UMAP, clustering in-browser!

Generating AI insights per node, even offline

Using WebGPU to render complex visualizations at 60fps

Compiling C++/Rust libraries into WASM to avoid server calls

And of course… making it usable for non-technical users, the hardest part

Again, why?

Because I believe people should be able to explore and understand their data, without needing a backend team or a technical manual.

Because I wanted to see data flow and to watch it transform live, like a living system.

I wanted something more alive. More exploratory. More fun.

Happy to answer anything about the tech stack, the challenges, or even ideas for doing this differently.

Thanks so much for checking it out and I’d truly love your feedback.
