GrayTabby is a simple tool that allows you to close all the tabs in your current browser and save them, as clickable links, in a dedicated window.

GrayTabby lets you see your tabs in a tree structure, so you can easily get back what you've lost.

You will only be asked to view your tabs and permissions when you need them. You'll never be forced to share any of your data.

If you're not ready to commit to its open source nature yet, you can donate to make it happen.

GrayTabby is simple and focused. It's not complicated, nor is it intrusive. It has a single button: your browser gets simplified. It's free.
