This is a visualization of JavaScript/CSS source map data, which is useful for debugging problems with generated source maps. It's designed to be high-performance so it doesn't fall over with huge source maps.
Drag and drop some files here or Upload files to get started. You can either drop a single JavaScript/CSS file with an inline source map comment, or a JavaScript/CSS file and a separate source map file together.
Or you can Load an example to play around with the visualization.
