Hi, I'm Tonis. I built bmux because I wanted the workflow I use in tmux to work in my browser too.
I wanted docs and apps side by side, separate project workspaces, and different logins in one desktop window. I also wanted my agents to browse without taking focus away from whatever I was doing.
With bmux, I keep research, personal browsing, and agent work in named sessions. Profiles keep logins separate, and I can mix them in the same split layout. Agents use the CLI to navigate, inspect pages, click, type, and take screenshots in the background. When I want to check their work, I attach to their session.
There are also floating reference panes, built-in keyboard click hints, and configurable Vim-style navigation. You can save layouts and detach a window while its pages keep running.
I've been using it as my daily browser for a few weeks. It's free and open source, and still an early preview. Extension support is experimental: there's a Bitwarden installer, plus built-in ad blocking and Dark Reader.
I'd love feedback from people who spend their day in the browser or work with coding agents. What would make this useful in your workflow?
