I'm building something powerful—and your support can help keep it alive

I'm dedicating everything I have to a project that means the world to me.

It's called iTensor, a free, open-source scientific platform created to empower students, researchers, and curious minds everywhere. It's designed to explore deep concepts like symbolic tensors, spacetime curvature, Einstein equations, and magnetic simulations—all directly in your browser, completely free. No barriers, just genuine curiosity and learning.

But here's my honest situation:

I'm currently living with my parents, pushing forward with barely enough to survive.
I've invested all my savings into servers, hosting, and domain fees—simply because I believe this tool deserves to exist.
I've sent out over 30 job applications after graduating with a degree in technical physics and showcasing iTensor and my other projects... but the silence has been deafening.
Almost every day, I work late into the night—usually until 11 pm, midnight, or sometimes even 2 am—handling everything myself: frontend, backend, symbolic computations, and complex C-based simulations. Recently, I've even lost access to some essential tools that were helping me speed things up.

Still, I'm not ready to give up.

My dream is clear: complete iTensor and keep it free and accessible to everyone.

But right now, I genuinely need support to keep going.

Here's how you can help:

💙 Support me with a coffee: https://ko-fi.com/itensor🔧 Hire me for tutoring or freelance work (math, physics, software development)—even short-term tasks make a huge difference🤝 Join forces with me—I'm open to collaborators passionate about open science and meaningful projects💬 Even a simple message of encouragement or feedback means the world to me

This isn't just about software—it's about proving that a single person, driven by passion and determination, can create something valuable for everyone.

Thank you deeply for your attention. If this resonates with you, please consider sharing it.

I built a relativity calculator in the browser (iTensor) — now trying to fully launch it

Hey Devs 👋
I'm Klaudiusz, a technical physics graduate with a passion for science + software. I created iTensor, an interactive tensor calculator for general relativity. It's powered by Python, SymPy, and a custom backend, which I'm still working to host publicly.

👉 Compute Christoffel, Ricci, Einstein tensors from your own spacetime metrics
👉 Learn GR with full docs: https://itensor-docs.com
👉 If you like the project, you can support it here: ko-fi.com/itensor

Any help — feedback, support, or ideas — means a lot! I'm solo-building this in my free time, and I want to keep it open, useful, and accessible.
