Orb runs each agent session inside its own container, with snapshots that stand in for git worktrees and let you fan one task out across parallel sessions.

Containers

Run agents in a container. Any session can run inside Apple's native container runtime on macOS 26, isolated from your Mac. The agent gets its own filesystem to work in, so a risky command stays inside the box.
Snapshot instead of worktrees. Set a session up once (install tools, clone your repos), then Save Snapshot to freeze that filesystem as the profile's baseline. New sessions boot from the snapshot with zero setup.
Run tasks in parallel. Launch several sessions from the same snapshot at once. Each is a copy-on-write clone, so they all start from identical state and run concurrently without stepping on each other.
Credentials stay out of the baseline. A snapshot is verified to contain no credential file before it is built, so secrets never bake into a baseline that later sessions inherit.

Sessions

Claude and a shell, side by side. Every session has a Claude pane and an on-demand Terminal pane, toggled in the dock header. Drop into a shell to inspect a diff or roll back a change while the agent keeps working. Both panes stay live.
Profiles. Local and container profiles live under one Profiles concept. You pick where a session runs when you create it.
Per-session stats. A dock-header glyph shows live resource usage: your Mac for a Local session, the running container for a container session.

Requirements

macOS 26 (Tahoe) or later.
