What is Boxes.dev?

On June 1, 2026, Nick and Drew launched boxes.dev – the first cloud-only Agentic Development Environment (ADE) where every Claude Code or Codex session gets its own computer in the cloud.

After a year of coding with Claude Code and Codex, the founders grew tired of leaving laptops open and managing complex git worktrees – so they built the solution they wished existed.

Key Features

  • Ultra-Simple Setup: Agent scans local dev environment and migrates to cloud
  • Multiple Clients: Desktop apps, CLI, and mobile apps – not just remote control
  • Uses Your Existing Subscription: Works with Claude Code and Codex
  • Full Isolation: Coding agents can run and test entire applications in isolated environments
  • Scheduled Automation: Slack integration for scheduled tasks
  • Parallel Workflows: Run multiple agents simultaneously

Pricing

10 free cloud hours for new users, then usage-based pricing.

Pros

  • No need to keep laptop open
  • Works from any device – mobile, desktop, CLI
  • Slack integration for automation
  • Isolated environment per agent
  • Supports parallel agent workflows

Cons

  • Requires Claude Code or Codex subscription
  • New platform with limited adoption
  • Pricing beyond 10 free hours unclear
  • May not suit all local workflows

Verdict

Boxes.dev solves a real problem for agent developers – leaving computers open. With 10 free hours, it is worth trying.

Rating: 4.3/5 - The cloud for coding agents.
