What’s inside
your Krot Box.

Your Krot Box is a real Linux machine in the cloud, one per person, that stays on. Your agents live and work there. Here’s what it is, what runs on it, and how your phone talks to it.

No. 02 / THE TOOLBOXPREINSTALLED

A full workshop,
ready to dig.

01 / THE AGENTS

Your agents, unmodified.

Claude Code, Codex and Cursor, plus open agents: OpenCode, Goose, Gemini CLI, Hermes and pi. Each comes from its maker’s own installer, and you sign in with your own account. GitHub Copilot and Grok Build are coming soon.

02 / A REAL TERMINAL

Everything a developer expects.

A terminal in your browser, with sessions that keep running when you close it. Git and the GitHub CLI, Node.js and npm, Python 3, build tools, ripgrep and jq. Your agents can install whatever else a project needs.

03 / ITS OWN BROWSER

Agents that check their work.

A headless Chromium browser lives on your Krot Box. Agents open the app they’re building, try it, and use it to send you screenshots and live previews, so you see it the way your users will before they call it done.

No. 03 / THE LINE TO YOUR POCKETPHONE, LAPTOP, ANY BROWSER

Your phone talks
straight to your box.

01 / YOU

ONE-TIME KEY

03 / Your Krot Box

Where the work happensYour chats stream from here directly to your browser, not through Krot’s servers.

NOTIFICATIONS

A tap when it matters.

When an agent asks a question or finishes and the chat isn’t open, your phone gets a notification.

VOICE

Talk instead of typing.

Your browser turns speech into text when it can; otherwise your recording is transcribed for you, in most languages.

THE APPS YOU KNOW

Claude and ChatGPT too.

Claude Code sessions also show up in the Claude app, and Codex in the ChatGPT app, so you can use whichever you like.

No. 04 / THE HANDOFFONE PROJECT. MANY HANDS.

Agents that pick up
where others left off.

SWITCHING AGENTS

A brief, not a blank page.

Switch a project to another agent and it works in the same folder, on the same files. It gets a brief of the conversation so far, newest first, and checks what changed before it carries on.

BUILT-IN INSTRUCTIONS

Agents that know the house rules.

Krot gives every agent instructions for working on your Krot Box: how to call in another agent, check each other’s work, test in the browser and show you previews and screenshots. Each project also has one instructions file that Claude Code, Codex, Gemini and the rest all read, so whoever picks up the work follows the same rules.

HELPERS

Agents that call in a colleague.

An agent can hand part of a job to another one, like Claude Code asking Codex to design the icon, then check its work and bring it back into the project.

AUTO RESUME

Usage limit? It waits, then carries on.

When Claude Code or Codex hits a usage limit, your box watches for the reset and continues where it left off. It’s on by default. Auto handoff, if you turn it on, moves the work to another of your accounts with room to spare.

No. 05 / YOUR OWN APPSPRIVATE BY DEFAULT

The apps you build
run on your box.

PREVIEW

See it in the chat.

When an app is running, your agent shows it to you in the chat, at a private address only you can open.

KEEP IT

On your home screen.

Save up to 20 apps, each with its own name and icon, and open them from your phone like any other app.

SHARE IT

Only if you say so.

Sharing an app by link stays off until you turn it on, and your agents can never turn it on for you. Krot isn’t a public web host: for a site the world can visit, your agent can publish it elsewhere.

No. 06 / YOUR STUFFLOGINS, FILES, SECRETS

Your logins and files
stay with you.

  • Logins happen on your box. You sign in to Claude, ChatGPT, Cursor and GitHub through their own sign-in pages, on your Krot Box. Krot never holds those logins.
  • Conversations stay on your box. Krot’s servers don’t keep your chats.
  • Your files, your way. Every project lives in its own folder. Browse, upload and download them from the Files tab, or have your agent push them to GitHub.
  • Secrets in a safe field. When an agent needs an API key, it asks for it in a secure field. The key is stored on your box and hidden from the chat.
  • Backed up every day. Our hosting provider backs up your Krot Box daily.
  • Leaving is easy. If your subscription ends, your box goes to sleep and is removed 30 days later. Download your files or push them to GitHub before then.

THE WORLD NEEDS THAT IDEA OF YOURS.

Stop being
the bottleneck.

Give your agents a computer that never sleeps and a way to reach you. Then go do something else.
