itk-wasm combines ITK and WebAssembly to enable high-performance spatial analysis in a web browser, Node.js, Python, and reproducible execution across programming languages and hardware architectures.

The project provides tools to a) build C/C++ code to WebAssembly, b) bridge local filesystems, JavaScript/TypeScript/Python data structures, and traditional file formats, c) transfer data efficiently in and out of the WebAssembly runtime, and d) asynchronous, parallel execution of processing pipelines in a worker pool. itk-wasm can be used to execute ITK or arbitrary C++ codes in the browser, on a workstation / server with Node.js or Python, or standalone execution and wrapped in WASI runtimes.
