If you use different browsers across different computers or operating systems, then you have been in the situation where you were looking at a web page on one browser but needed that information on another browser at another computer.

Cache Nut is a browser extension for Firefox and Chromium-based browsers that allows copy-pasting between different types of browsers across computers. The copied data can be page content, page or tab locations, and image or link URLs. The data can be pasted when the computers are not on the same network by using the Cache Nut cloud as an intermediary. The information is end-to-end encrypted between browsers, and is not visible to any other party including Cache Nut servers.

The browser extension is available for Brave, Chrome, Edge and Firefox browsers. It will be available for other browsers in the future. In the meantime, it can be installed manually with the early access release.
