box vs Worktrunk: Features, Pricing & Which Is Better (2026)

A side-by-side comparison of box and Worktrunk — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

box is a cheap, powerful Linux VM sandbox for AI agents — a persistent Ubuntu machine with SSH, Docker, a virtual desktop, and fast snapshot forking.

Persistent Linux VM per Agent: Each box is a real Ubuntu virtual machine with SSH and SCP access, not a stubbed or ephemeral container.
Dedicated IPv4 Address: Every machine gets its own public IPv4, so outbound traffic and network-scoped tools behave like a real server.
60fps Virtual Desktop: A high-framerate virtual desktop lets vision-enabled agents interact with GUI apps and browsers naturally.
Disk-Level Snapshot Forking: Fork a machine from a snapshot in seconds so agents can branch execution and discard failed paths cheaply.
Docker-in-Box: Docker runs inside the VM, so agents can build and run containerized workflows without a nested-host bailout.
Preloaded Agent Toolkit: Ships with Docker, VS Code, Chrome, Ghostty, GitHub CLI, Rust, Node.js, and Bun preinstalled.
Cross-Platform CLI: A single install command (curl or PowerShell) drops a fetch-friendly CLI on macOS, Linux, and Windows for both agents and humans.

Agent Factories: Spin up thousands of isolated Linux sandboxes as the substrate for a fleet of autonomous agents.
Coding Agent Environments: Give a coding agent a real machine to clone repos, run tests, and open a browser during work.
Browser Automation with Vision: Run a full Chrome instance on the virtual desktop so a vision agent can drive real web UIs.
Task Branching: Snapshot a VM before a risky action, fork to try alternatives, and merge back the winning path.
Reproducible Bug Repros: Fork a known-good snapshot to reproduce a bug in an identical environment on demand.
Human + Agent Shared Workspace: A human developer SSHes into the same box an agent is working in for pair debugging.

A Rust CLI that makes git worktrees as easy as branches, built for running several AI coding agents in parallel without collisions.

Branch-Addressed Worktrees: wt switch, wt remove, and wt list refer to worktrees by branch name with paths computed from a configurable template, replacing multi-step git worktree incantations.
Agent Launch in One Command: wt switch -c -x claude <branch> creates the worktree, enters it, and starts the agent in a single invocation.
Lifecycle Hooks: Run commands automatically on create, pre-merge, and post-merge to automate setup and teardown for every new worktree.
LLM Commit Messages: Generates commit messages from the diff so parallel agent branches stay legible without hand-writing every message.
One-Command Merge Workflow: Squash, rebase, merge, and clean up the worktree and branch in a single step rather than a sequence of git commands.
Interactive Picker: Browse worktrees with streaming CI status alongside diff, log, PR, and comment previews before switching.
Shared Build Caches: wt step copy-ignored gives ten worktrees their own target/ and node_modules/ without rebuilding or copying, using reflinks on APFS, btrfs, and XFS.
Per-Worktree Dev Servers: A hash-port template filter assigns each worktree a unique port so parallel dev servers do not conflict.

Parallel Agent Runs: Give each of five to ten concurrently running AI coding agents its own worktree so their edits never collide.
Fast Branch Context Switching: Jump between in-flight changes by branch name instead of navigating sibling directories by path.
Pull Request Review: wt switch pr:123 checks out a pull request's branch directly for local inspection or testing.
Monorepo Iteration: Share heavy build artifacts across many worktrees so each new branch is usable immediately instead of after a full rebuild.
Automated Branch Setup: Use create hooks to install dependencies, copy env files, or start services whenever a worktree is made.
Multi-Branch Status Review: wt list --full shows CI status and AI-generated summaries for every active branch in one view.
