box vs Code Review Graph: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of box and Code Review Graph — 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.
Key features
- 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.
Best for
- 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.

Code Review Graph

Code Review Graph is a local-first code intelligence graph for MCP and CLI that cuts AI coding tool context by mapping only what matters.
Key features
- Persistent Repo Graph: Builds and maintains a graph of the codebase's symbols, references, and structure so lookups are instant on subsequent runs.
- MCP Server Integration: Exposes the graph as an MCP server so Claude Code, Cursor, and other MCP-compatible agents can query it directly.
- CLI Access: A first-class command-line interface lets developers query the graph without an agent in the loop.
- Task-Scoped Context Slices: Instead of loading whole files, returns only the pieces of code an AI tool needs — with benchmarked context reductions.
- Local-First Privacy: All indexing and serving runs on the developer's machine, so source code never leaves the environment.
- PyPI Distribution: Installs with a single `pip install code-review-graph` and works on any Python 3.10+ setup.
Best for
- Cheaper AI Code Reviews: Feed only the relevant slices of a change to a review agent so token spend on large PRs stays low.
- Large Monorepo Workflows: Give coding agents targeted context in repos too big to fit into any model's window.
- MCP-Compatible Agent Enhancement: Plug into Claude Code or Cursor as an MCP server to add repo-aware retrieval.
- Local Refactor Planning: Use the CLI to explore dependencies and impact before making cross-cutting changes.
- Air-Gapped Codebases: Keep proprietary source local while still using AI tools that consume the graph rather than raw files.
- Onboarding Assistance: Help new engineers navigate a large codebase by querying the graph for related symbols and callers.
