RunMat (formerly Dystr)

Dystr is an engineering software company whose current product is RunMat, a GPU accelerated runtime for math that runs MATLAB syntax code in the browser, on the desktop or from a command line. Engineers keep writing in a syntax they already know while RunMat compiles the code and schedules it across CPU and GPU cores, fusing chains of elementwise math and reductions into as few GPU dispatches as possible and handling data movement automatically. It is aimed at engineers and research teams doing serious math and physics work, such as simulation, analysis and plotting. A GPU accelerated 2D and 3D plotting engine keeps figures live and interactive rather than static. RunMat is designed for agent in the loop work: an AI agent can see runtime figures and variable state, operates under an explicit read and write policy, and accumulates reversible change sets that people review. It supports embedded ChatGPT and Claude executions and a desktop MCP server, along with shared cloud projects, real time collaboration, and version and run history for files and outputs. Teams can use it locally, in the cloud or self hosted. RunMat is free on the web and desktop. The Free plan includes the runtime and CLI, desktop app, unlimited cloud projects and collaboration, 30 days of version and run history, 50 Agent credits per active member each month and 2 GB of cloud storage. Extra Agent credits cost $10 for 100, and extra storage is $5 per month per 10 GB. Enterprise is quote based and adds SSO, SAML and SCIM, audit controls, private or air gapped deployment, managed FEA workflows and remote parallel workers. The Dystr site now serves mainly as a pointer to RunMat, so buyers should evaluate RunMat directly.
