§ free browser tool
Online GDS Viewer & Layout Editor
A real EDA layout tool, compiled to WebAssembly - open a GDS in your browser.
Launch the tool →This is a browser build of Entropic, an open programmable EDA platform written in Rust with a KLayout-style core. The layout tool ships here as WebAssembly, so you can open GDSII files, style them with .lyp layer-properties files, browse the cell hierarchy, and work the layer panel without installing anything.
Files are parsed entirely client-side: nothing is uploaded, which matters when your layouts are under NDA. It is an experiment in web-deploying a native application, so expect it to be slower than the desktop build - but it is a genuine viewer/editor, not a screenshot gallery.
Typical uses: quickly inspecting a GDS someone sent you, checking layer mapping against a .lyp, sanity-checking a tape-out cell hierarchy from a machine without EDA tools installed.
