boxes.dev gives AI coding agents their own cloud Linux machines, or "devboxes," so they can run independently while users manage them from Slack, Linear, the terminal, or a mobile device. The platform supports bringing your own Codex or Claude subscription, and sleeping devboxes are free to keep costs down. Users can trigger agents via API, schedule them on cron jobs, or assign issues directly from Linear with results reported back in-thread.

Problem
AI coding agents typically run in local worktrees, which ties them to a single machine and requires the user to remain present. This limits parallelism, makes remote steering difficult, and prevents agents from continuing work while the developer is away or on another device.
Solution
boxes.dev gives every AI coding agent its own dedicated cloud Linux machine, called a devbox, with a full filesystem, preinstalled dev environment, and port forwarding to localhost. Users can start agents from Slack, Linear, a schedule, or a single API call, and receive results in the same context where the work was requested. Since each devbox is isolated by default, agents can run in parallel without resource conflicts or port juggling. Devboxes sleep automatically when idle, so agents keep working when you close your laptop, and only active machines incur costs.
Target Audience
Primary users are software developers and engineering teams who use AI coding agents like Codex or Claude and need scalable, remote-managed execution environments integrated into their existing Slack, Linear, and CI workflows.
Features
- Full cloud Linux computers with own filesystem, port forwarding to localhost, and preinstalled dev environment
- Native Slack integration: tag @boxes.dev in any channel or thread to start work and get results in-thread
- Linear integration: assign an issue to boxes.dev and the agent reports back with outputs or PRs attached
- Scheduled runs via cron for Codex or Claude, enabling nightly QA, recurring updates, or commit reviews
- REST API that starts a devbox and thread with a single POST request, supporting webhooks and CI triggers
- Automatic sleeping of idle devboxes to make parallelism cost-effective
- Cross-surface management from desktop, phone, or terminal, including reading threads, approving requests, and reviewing diffs
