Review of fanbox
Vibe coding - the practice of directing AI coding agents (Claude Code, Cursor, Aider) to build features while you mostly watch - has a visibility problem. The agent makes changes across multiple files, your terminal is full of logs, and you lose track of what just happened.
fanbox is a desktop app that gives you a proper cockpit view: file tree on the left, terminal on the right or below, and the change diff highlighted in the center. The 'every change visible' design is the killer feature - you see exactly what the AI did, line by line.
If you ship AI-assisted code daily, fanbox pays for itself in the first hour. The mental load of tracking AI agent changes is real, and fanbox reduces it to a glance. Indie hackers, prototyping founders, and AI-tooling enthusiasts will love it.
Cursor and Claude Code have their own diff viewers, but they're embedded in the editor. fanbox is a separate window that you can put on a second monitor or split-screen. The dedicated focus helps when you're reviewing agent output across many files.
A small, focused tool that solves one problem well. The vibe coding community will appreciate it. Worth a try if you've ever had an AI agent silently break something in a file you weren't watching.
