Multi-Window Launcher

The Multi-Window Launcher is a free tool that helps you manage many web pages at the same time. It lets you open several websites at once in a grid. This means you won't have to get annoyed switching between too many tabs.

Benefits

The Multi-Window Launcher makes it easy to see and use multiple web pages together. You can choose different ways to arrange them, like two rows of two windows or one row of four. The tool even changes the layout automatically depending on how many windows you open. You can also save groups of websites you use often. Then, you can switch to those saved groups right away. This saves you time and effort.

Use Cases

This tool is great for many situations. For example, you can use it to compare different AI chatbots like Claude, ChatGPT, Gemini, and Perplexity side by side. It's also helpful for organizing your business tools, doing research for investigations, or looking at code in different places. If you have more than one computer screen, the Multi-Window Launcher can help you spread your windows across them. You can even choose which screen the windows first appear on. It also lets you minimize all your windows with one click or bring them back. You can even use keyboard shortcuts for these actions.

Vibes

Users appreciate how this tool simplifies managing multiple browser windows, making tasks that require comparing information or using several tools much easier. The ability to save and quickly switch between sets of URLs is frequently mentioned as a significant time saver.
