box Review

Welcome to Box, the ultimate sandbox for your agent endeavors. Forget complex setups; Box provides simple, powerful Linux VMs designed specifically for building profitable, long-running agents as a service. It’s not just a VM; it’s a persistent Linux environment, complete with SSH access, Docker support, and a dedicated IPv4 per machine, all launched with a single command: box new.

Box by ASCII delivers unparalleled value, making it significantly more affordable than alternatives like E2B, GitHub Codespaces, or Daytona. For just $20, you get 555 hours of dedicated 4 vCPU / 8 GB VM-time, billed by the second. This means more compute for your buck, empowering you to scale your agent factories without breaking the bank.

Main Features

• Persistent Linux VMs: Full Ubuntu machines with SSH/SCP access, ensuring your work and state are always preserved.
• Docker Inside: Develop and deploy containerized agents effortlessly, as Docker comes pre-installed.
• Dedicated IPv4: Each Box gets its own IP, perfect for agents requiring external accessibility or unique network identities.
• Pre-configured Dev Environment: Comes loaded with essentials like VS Code, Chrome, GitHub CLI, Rust, Node.js, and Bun – ready for any devtool or language.
• Fast Disk-Level Forking: Clone from a snapshot instantly, accelerating development and experimentation.
• Programmatic Control: Utilize the intuitive CLI (box new, box ssh, box prompt) or comprehensive HTTP API and SDKs for automated workflows.

Main Target

• AI Agent Developers: Bring any agent framework—Claude Code, Codex, OpenCode—and run it in an optimized environment.
• Agent Factories: Ideal for those building and managing fleets of autonomous agents as a service.
