We startedboxes.dev becauseour agents outgrewlocalhost.

We’re Nick and Drew. We met at MIT, then spent the better part of a decade building Gem together — Nick as co-founder and CTO, Drew as the first engineer — growing it to roughly 300 people and a $1.2B valuation.

For the last year we’ve coded almost entirely with Claude Code and Codex. It changed how we build — but we kept hitting the same wall: localhost. Worktrees were clunky, laptops had to stay cracked open, and parallel agents fought over one machine.

We couldn’t find a tool that fixed all the pain points, so we built the one we wanted. boxes.dev gives every agent its own computer in the cloud — reachable from your desktop and your phone.
