TabTabTab Overview

TabTabTab gives you a cloud laptop for coding. Your editor, terminals, dev servers, preview URLs, browser testing, and agent sessions run on a persistent VM in the cloud instead of your machine, so the work keeps going no matter which device you pick up.

Why people use it

  • Code from any screen, like a Nintendo Switch for coding. Drive the same workspace from your laptop, phone, tablet, or TV. Walk away from your desk, check in from the couch, steer an agent from a coffee shop, all against the same running session. No syncing, no "wait, my laptop is at home."
  • Stop babysitting long agent runs. Kick off a multi-hour agent or build and close the lid. It keeps running on the VM, not your machine, so battery, sleep mode, moving rooms, and Wi-Fi drops don't kill it. Come back when it's done.
  • Keep branches and experiments isolated. Each workspace is its own git worktree backed by a devcontainer, so feature work, fixes, and experiments do not share mutable state. The cloud VM is doing the work, not your laptop.
  • Test your app in a real browser without leaving the workspace. Any port your dev server opens on the VM gets a public preview URL. We proxy traffic from the cloud machine to your browser, so you can click through the live app on desktop or mobile, share the link with a teammate, or point a webhook at it. No ngrok, no SSH tunneling.
  • A web-first coding environment around model choice. Today the TabTabTab IDE is based on our OpenCode fork. You can sign in with Codex or bring OpenRouter, Anthropic, OpenAI, and other supported model-provider API keys. Harness-neutral switching is where we're headed, but the current product experience is the TabTabTab IDE on a persistent cloud machine.
  • A browser agent that runs your app and verifies it works. TabTabTab includes a browser agent that starts your dev server itself, opens the app in a real browser, clicks through it, and reports back on whether things actually work. You don't need to spin up the server or hand it a URL. Useful for smoke tests after a coding agent's change, UI bug repro, and closing the "did this actually render right?" loop without leaving the IDE.

What it isn't

  • Not a hosted Git provider. Bring your own GitHub repos.
  • Not a replacement for your local editor if you prefer to stay local. You can still connect VS Code, Cursor, or SSH to the cloud environment instead of using the Web IDE.
  • Not a managed production runtime. Environments are for development, not for hosting customer traffic.

The three surfaces

TabTabTab has three places you'll touch it:

  • Web IDE. The main interface. Built from our OpenCode fork, with TabTabTab cloud compute, repo onboarding, Secret Manager, Codex login, model-provider API keys, environment metrics, runtime previews, mobile access, and dashboard handoff layered on top.
  • CLI (tabtabtab / ttt). The local bridge. Authenticate, create environments, open the workspace in VS Code or Cursor, SSH in, upload files, onboard repos, manage env vars, and expose runtime previews.
  • Meta UI (https://dash.tabtabtab.ai). The control surface for your cloud environments. Create them, watch provisioning, open the Web IDE through one-time links or QR codes, connect GitHub and model providers, and update runtime components.

Model access and editors

  • Codex login. Sign in with ChatGPT Pro/Plus when you want cheap Codex access.
  • Provider API keys. Bring OpenRouter, Anthropic, OpenAI, and other supported model-provider keys.
  • OpenRouter credit. Beta users get $50 of OpenRouter credit by default.
  • Harness switching. We want TabTabTab to be harness-neutral, including Claude Code and other agent CLIs, but that is not the first-class product experience today.
  • Browser agent. Bundled. It can open a preview URL, click through your app, and feed observations back to a coding agent.
  • Local editors. Attach VS Code, Cursor, or plain SSH to the cloud environment with tabtabtab open vscode, tabtabtab open cursor, or tabtabtab ssh. Useful if you'd rather stay in your local editor while the work runs in the cloud.

Recommended path

Start in the Meta UI, create an environment, open the Web IDE, add a repository from the left-sidebar plus button, and review detected secrets. Install the CLI when you want local shell access, uploads, automation, or runtime commands.

curl -fsSL https://tabtabtab.ai/install.sh | sh
tabtabtab auth login

If something doesn't work or you need a feature that isn't documented, email support@tabtabtab.ai.
