A free, open-source browser with split panes, named sessions, and separate profiles in one window. Browse with keyboard shortcuts while agents work in background sessions through the CLI. Attach whenever you want to see their work.Split pages horizontally or vertically, keep references in floating panes, and use keyboard click hints or configurable Vim-style navigation. Profiles keep logins and storage separate, and can share a split layout.Agents use the CLI to navigate, inspect pages, click, type and take screenshots in background sessions. Attach to a session whenever you want to check their work.bmux is free and open source under GPLv3, and still an early preview. Desktop releases are available for macOS and Windows, with portable Linux hosts for remote access. It does not require tmux.Website: https://bmux.cc/Source: https://github.com/tonisives/bmuxDemo: https://youtu.be/_AHo0C1rVWE
