Free your coding agents.
Give every agent its own cloud computer. Bring your Codex or Claude subscription, start agents from Slack and Linear, and manage them from your desktop, phone, or terminal.
Manage your agents
from any surface.
With your dev environment in the cloud, every surface is a first-class client.
Steer agents while on the go. Not a remote control: read threads, approve requests, review diffs, or open a terminal.
Linux machines in the cloud,
not local worktrees.
boxes.dev gives each agent a whole computer that’s already running your dev environment (a “devbox”), and a way to steer that agent from anywhere.
Full computers, not worktrees.
A real Linux box with its own filesystem, port forwarding to localhost, and your dev setup preinstalled.
Isolation by default.
A fresh cloud machine for every meaningful body of work. No resource constraints, no port juggling.
Agents run while you’re away.
Close your laptop, go to bed, touch grass. Your agents keep working in the cloud.
Sleeping devboxes are free.
Idle boxes sleep automatically, so parallelism doesn’t turn into runaway costs.
three tasks → three fresh devboxes → Codex + Claude in parallel
Start from anywhere.
Slack, Linear, a schedule, or an API call.
Start a new agent on a devbox, get results where you asked for them.
SlackTag @boxes.dev to start work from any channel or thread. The agent gets the context and reports back in-thread.
LinearAssign an issue to Boxes.dev. The agent reports back in Linear and attaches any outputs or PRs.
ScheduleCodex or Claude on a cron: use to review past commits, post recurring updates to Slack, or run nightly QA on your app end to end.
APIOne call starts an agent on a fresh devbox. Wire up webhooks, CI, or anything else.
Pick any thread up later in your boxes.dev workspace and keep iterating. Optionally post agent responses to any Slack channel.
$ curl -X POST api.boxes.dev/v1/threads \
-d '{ "project": "web",
"agent": "codex",
"prompt": "fix flaky auth test" }'
✓ devbox + thread started
From your laptop to the cloud
in three steps.
No complicated dev setup script. No new harness. boxes.dev migrates your dev environment to the cloud automatically, and runs the same Codex or Claude Code subscription you’re already using.
Choose a local dev environment.
Pick a local folder or a GitHub repo. boxes.dev looks at your dev environment and drafts a setup plan.
Port your setup to the cloud.
Approve the setup plan: see exactly what will be installed. Then an agent executes the plan and makes sure your app runs on the remote box.
Take a snapshot—filesystem and memory.
Then get to work! Each agent gets a new devbox. Devboxes start from the snapshot in seconds.
We couldn’t find an ADE with
everything we wanted — so we built it.
Run native Claude Code and Codex on fresh cloud copies of the dev environment you already have running. Keep the same work in reach from the graphical workbench, the agent’s terminal UI, or native mobile.

Roll it out responsibly.
Safely give your team the power of cloud agents.
A worktree gives you another checkout on the same machine. A boxes.dev
devbox gives you another computer—its own filesystem, processes, ports, and database state—created from a Template box snapshot. Each agent can run your app, change dependencies, edit the database schema, or break things without affecting the others.
Close your laptop again.
Develop in the cloud: one computer per agent, running your full app, steerable from every device you own.
