cirq — design your electronics

cirq is a modern solution for schematic and layout editing, runnable in your web-browser, but working fully offline. What, a browser-based offline solution? Yes, you can use this application from within your browser, but all of your data is hosted offline an will never sent via the network: the browser is just the easiest way to obtain the software. You can even install this as a so-called progressive web app, which leads to a native feeling on all devices.
