OIOXO
Start here

Getting started

There is no setup. The landing page of oioxo.com is the IDE — you type what you want to build, and OIOXO builds it in front of you.

Your first build

  1. Describe it. Type one sentence into the prompt box — e.g. “a pomodoro timer with a circular progress ring” — and press Enter (or click Start). Three example prompts sit under the box if you want a one-click start.
  2. Watch it build. OIOXO shows each step as it goes: Planning → Writing code → Running → Checking. The first time, it also downloads the coder that runs on your device (a one-time download your browser keeps — see Models that run on your device).
  3. Open it. When the build verifies green, click Open it for a live preview, View code to inspect every file, or Download to take the project with you.
  4. Keep going. Ask for changes in plain language — the agent edits the project, re-runs it, and verifies again. Every change is snapshotted, so anything can be undone.
Tip

Be concrete about what you want to see: “a snake game with a score counter and a restart button” builds better than “a game”. The agent turns your words into the checks it has to pass.

What can it build?

OIOXO detects the right project shape from your prompt: static web pages and games (instant, server-free preview), React apps and APIs (run in an in-browser Node sandbox), command-line tools, and scripts in Python, SQL, PHP, and Lua — every one of them runs right on your device and is previewed in the page. There’s no language server to install and nothing leaves your machine to run it.

Working on existing code

The prompt box is only half the IDE. From the rail on the left you can also open the Workspace — work on any local folder (nothing is uploaded — the folder opens directly in your browser) or open a GitHub repository and push changes back, switching source in the title strip. See The editor.

Browsers

The live preview and terminal need a Chromium browser (Chrome, Edge, Brave). Other browsers can still scaffold projects and edit files; the desktop app previews everywhere.

Accounts

You can run your first build without an account. After that, a free account keeps you building — no card, no trial clock. Allowances and Pro are covered in Plans & usage.

Beyond the browser

The web app is the fastest way to start, but OIOXO is wherever you code: on your phone, as a desktop app with bigger models and full file access, and inside VS Code. One account ties them together — see Choosing your platform.
