Who we are
RunMat is a fast, open-source runtime that runs MATLAB-syntax code on GPU. We built it because we saw the problem firsthand: talented engineers losing time to slow tools, expensive licenses, and workflows that couldn't keep up with modern hardware.
We started with Dystr and learned a simple thing: engineers don't want a new platform. They want their current workflow to run faster and feel modern. That led us to RunMat. Read more about why we built RunMat.

Who is RunMat for
RunMat is for people who do math on a computer:
- Simulations and control systems
- Signal and image processing
- Finance, risk, and research
If you've ever felt stuck between MATLAB's readability and Python's openness, RunMat gives you both, plus real GPU speed.
Whether you're migrating off expensive MATLAB licenses, looking for GPU acceleration without learning CUDA, or building workflows where AI writes code and humans verify it, RunMat fits.
Easy to read, fast to run
Code generation is speeding up. More code gets written fast, but checking results is still slow.
Many engineers stay on MATLAB for readability, but deal with licenses and performance limits. Others move to Python and gain openness, but lose the math-like syntax that makes code easy to review.
We think MATLAB-style syntax matters more than ever because it's easy to read. As AI writes more first drafts, humans still need to verify results fast. RunMat is built for that.
Our mission
To enable people to do math and physics that they couldn't do before by creating a modern, high-performance alternative to MATLAB.
We focus on performance, portability, and developer experience, without breaking the way engineers already write math. That means a runtime that's fast, secure, and built for today's hardware.
What is RunMat today
RunMat is an open-source runtime for math that runs MATLAB-style code in the browser, desktop, or CLI, and can automatically run work on CPU or GPU.
Automatic GPU acceleration via kernel fusion
~5ms startup (about 180× faster than GNU Octave)
Async support so long work doesn't lock up your app
Built in Rust for portability
Browser sandbox: run code instantly, no install
Fast plotting and visualization (improving quickly)
Language tools (LSP + linter) for autocomplete and error checks
Clear errors that help you fix issues fast
Available now: air-gapped deploys, local-first runs on your hardware.
Coming very soon: saved projects, team orgs/projects, roles + SSO, large-file storage with resumable uploads, and version history.
Where we're headed
You can use RunMat today as a MATLAB-style runtime. Next, we're building it into a modern environment for engineers where:
Open source at the core
The core runtime is MIT licensed and on GitHub. The JIT, the fusion engine, the GPU planner. We're committed to keeping it open source and actively maintained.
Run MATLAB code online - no install, no license
Start running math immediately in your browser.
We're based in Seattle, WA and San Francisco, CA. Reach us at team@runmat.com
