About Boxes.dev
Summary
Boxes.dev gives AI coding agents, specifically Claude Code and Codex, dedicated cloud Linux machines so they can run in parallel without competing for local resources. Developers trigger agents from Slack, Linear, a schedule, or an API call, then monitor or steer them from a desktop app, mobile device, or terminal. It replaces local worktree setups and the need to keep a laptop open while agents work.
Business model
A free tier for individuals plus paid team plans, with idle boxes sleeping automatically to avoid runaway costs.
Go-to-market
Individual developers and engineering teams adopt it self-serve via a Mac download, bringing their own Codex or Claude subscriptions.
From the Y Combinator listing
A better place to run your coding agents.
Close your laptop again. Run Claude Code and Codex on unlimited parallel cloud computers from your laptop, phone, and terminal. Bring your own subscription, start agents from Slack and Linear, and manage an agent swarm by letting your agents coordinate their work.
