Boxes.dev

boxes.dev is a specialized Cloud Development Environment (CDE) platform engineered specifically for parallel AI coding agents, such as Codex and Claude Code. Unlike traditional cloud IDEs or local worktrees that focus on branching code, boxes.dev is designed to provision, manage, and orchestrate independent, isolated computing environments where multiple AI agents can execute complex coding tasks concurrently without resource conflicts.

Key Features & Architecture
Isolated Cloud "Forks": Instead of simple git checkouts, the platform generates a full Linux virtual machine (a "fork") for each agent thread. Every fork duplicates the primary development environment—complete with its filesystem, background services, ports, and local database states—allowing agents to run tests, alter schemas, or modify dependencies completely in isolation.

Asynchronous Persistent Execution: Because agents run entirely on cloud infrastructure (defaulting to 4 vCPU / 8 GiB instances), tasks survive local di
