A WebKit browser for macOS with tasks at the center.

• Organize your work as tasks, with a tree of tabs for each task.
• Keep an optional agent beside each task: Bello’s own engine or an agent connected through the Agent Client Protocol (ACP).
• Browse privately from your agents. No agent tool or API exposes your tabs, terminals or their contents.
• Open terminals as tabs inside a task, running your own login shell.
• Keep shared Knowledge: notes with their history, a discussion thread, and a review queue that flags notes when their sources change or their review date comes.
• Bring your BelloTTT trees over from a snapshot export.
• Browse with WebKit, the engine behind Safari, in Bello Browser’s own window.
• Keep tasks, notes and conversations locally on your Mac. Connect the model providers and agents you choose.

Requires macOS 14 or later and Apple silicon. To install, open the disk image and drag Bello Browser to Applications.
