iTensor
Open Scientific Computing in Your Browser
A free, open-source scientific engine for physics, general relativity, and differential geometry. Built to bring advanced tensor calculus, symbolic computation, and numerical simulations directly into the browser.
Why iTensor?
Modern science relies on symbolic and numerical tools like Mathematica or Maple, but these are expensive, closed-source, and often out of reach for students, researchers, and independent developers.
Tensor Algebra
Perform real-time tensor calculations with support for Riemann, Ricci, Einstein, and Weyl tensors directly in your browser.
Open Source
Built with transparency and extensibility in mind, enabling collaboration and customization for your specific needs.
Educational Access
Accessible to anyone, anywhere—from students to researchers—without the barriers of expensive proprietary software.
Key Features
- Real-time tensor algebra in the browser
- General relativity support: Riemann, Ricci, Einstein, Weyl tensors
- Differential operators: Laplacian, divergence, gradient
- Symbolic and numerical backend using SymPy and a Django API
- Early support for magnetohydrodynamic (MHD) simulations
Who Is Behind It?
Klaudiusz Sroka
iTensor is a solo project by a scientific software developer with a background in technical physics, general relativity, and system design. It is built with passion, but its ambition demands support.
Follow on GitHubWhat We Need
To continue developing iTensor and make it an even more powerful tool, we need support in several key areas:
Infrastructure
Server costs, backend compute resources, and bandwidth to keep the platform running smoothly for all users.
Development
Time and resources to finalize the C-based numerical engine and desktop interface for more advanced calculations.
Education
Design and UX polish for education and outreach to make advanced physics concepts accessible to more people.
Scientific Validation
Collaboration with physicists and mathematicians to ensure accuracy and relevance of all calculations and simulations.
Community
Building forums, feedback tools, examples, and tutorials to create a thriving community around open scientific computing.
Project Roadmap
Our vision for iTensor extends far beyond its current capabilities. Here's where we're headed:
