FanBox: a cockpit for vibe coding with AI agents
Week 2026-W25 ·
FanBox is a desktop app that puts your files, your terminal and a live diff in one window so you can watch a coding agent work in real time. It passed 580 stars within days.
FanBox is a desktop workspace for driving AI coding agents like Claude Code and Codex. It fuses three things that usually live in separate windows: a file browser on the left, an embedded terminal on the right, and a live view of changes in the middle. As an agent edits files, they highlight in place, and git diffs show exactly what was altered. It's an Electron app using xterm.js for the terminal and Monaco for code, and it's local-first, so your data stays on your machine. It took off because it makes an agent's work visible instead of a black box.
Why a vibe-coder should care
For anyone vibe coding with an agent, FanBox turns guesswork into a clear picture: you see each change as it happens and stay in control without flipping between editor, terminal and file manager. Less context-switching, fewer surprises in your repo.
