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

A side-by-side comparison of box and tterm — 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.

Free

Free macOS workspace that unites a terminal, a real Chromium browser, and Claude Code in one hot-reloadable, self-building window.

Self-Building Workspace: ⌘K invokes Claude Code on tterm's own source and hot-reloads the running app so you can extend the tool from inside itself.
Row-Per-Project Layout: Every project gets its own row containing an explorer, a Claude Code session, and a file viewer, so multiple projects stack side by side.
Embedded Real Browser: ⌘B opens a Chromium tab inside tterm that inherits your Chrome cookies, bookmarks, and history — favicons and all.
Diff-Only Review: ⌘G opens a hunk-level diff reviewer for staging and committing changes; there's no editor by design, so you review instead of retype.
Command-Palette Shortcuts: ⌘K palette, ⌘O projects, ⌘P quick open, ⌘⇧F search, ⌘F find, ⌘⇧M for CLAUDE.md, and more make navigation keyboard-first.
Terminal-Respecting Key Handling: Only ⌘-chords are intercepted by tterm; every ⌃-key passes through to the pty untouched, so terminal apps keep working.
Privacy by Default: No account, no telemetry, and no network calls home — the app is a single ad-hoc-signed hobby build.

AI-Paired Coding: Keep Claude Code, your terminal, and docs in one window while pairing with an LLM on a project.
Multi-Project Juggling: Stack several concurrent projects as rows so you can jump between them without alt-tabbing.
Doc-Grounded Development: Use the embedded browser to keep API docs open next to your terminal and diff without leaving the app.
Focused Diff Review: Review and stage AI-generated changes hunk by hunk before committing, rather than editing in place.
Hobbyist macOS Tinkering: Extend the tool itself from inside via Claude Code, treating tterm as a live playground.
