ABOUT:
Your browser is already where work happens — Slack, GitHub, Linear, docs. Everything except your agents. Every time you alt-tab to a terminal or editor, you're breaking the flow that makes parallel agents worth running in the first place.
Workbench puts your agents where everything else already is. A 20MB Go binary that serves terminals, worktrees, file editing, and git diffs in a single browser tab. Localhost only — no account, no cloud, no Electron. Your code never leaves your machine.

FAQ:
+-What is Workbench?
A lightweight Go binary that serves your entire AI coding workspace in a browser tab — worktrees, terminals, file editor, and git diffs, all in one place. No Electron. No separate app to install.
+-What agents does it work with?
All of them. Workbench runs a real terminal per worktree, so any agent that runs in a terminal works out of the box: Claude Code, Codex, Aider, OpenCode, Goose, and anything else you can launch from the command line.
+-How does it differ from tmux?
tmux multiplexes terminals in the terminal. Workbench gives you a full browser-based UI with parallel git worktrees, a built-in file editor, git diffs, and agent status — all without leaving your browser tab.
+-What OS does it support?
macOS. Linux and Windows support coming. The binary is under 20MB and has no runtime dependencies.
+-Is it free?
Yes. Workbench is free and open source. Source code is available on GitHub.
