ITK-Wasm combines ITK and WebAssembly to enable high-performance spatial analysis in a web browser or system-level environments and reproducible execution across programming languages and hardware architectures.

The project provides tools to

  • build C/C++ code to WebAssembly.

  • bridge local filesystems, JavaScript/TypeScript/Python data structures, and traditional file formats.

  • transfer data efficiently in and out of the WebAssembly runtime.

  • perform 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 the command line, and in languages like Python via WASI and Emscripten runtimes.
