🚀 Small on purpose
The starter pack focuses on the essentials: one browser bundle, a short quick start and examples that are easy to inspect.
📦 SDK Lite v8.6.0
Build your first visible RTO tab integration faster
RTO SDK Lite is the practical starter kit for browser-side integration. It gives you one bundle, a tiny quick start and local examples so you can detect the extension, request allow-list approval and control a real visible tab without reading the full documentation first.
Version details
Docs updated: 2026-08-22
SDK package: 8.6.0
Built against plugin behavior: 8.6.0
👁️ Real visible tabs
The examples are built for the actual RTO model: named tabs, visible focus changes and user-approved control.
🛡️ Explicit boundaries
Your page talks to the local RTO bridge. Hosts still need explicit approval, and the user can see what is happening.
⬇️ Download
Download the SDK Lite package
Use this package when you want the simplest possible starting point: local demos, first integrations, quick proof-of-concept work or learning the basic RTO browser-side flow without pulling the full helper tree.
🧩 What is included
Everything you need for a clean first integration
The all-in-one browser bundle for quick page-side integration.
The minimal path: include the bundle, connect once, request approval, and open or reuse a controlled tab.
The fastest proof that connection, open, focus and close work.
Visible overlay cursor, styled labels and PNG cursor support.
A richer local flow that goes beyond one small test.
A stable local target page used by the bundled demos.
Not duplicated here: the full documentation tree, helper packs and larger website resources. Use the main site when you need the full reference.
🚀 Quick start
Start in 3 small moves
1. Include the bundle
Add RTO.min.js to your page, then verify that the extension responds.
2. Ask for allow-list approval
Use the modern request flow. The user must approve it on the matching master tab.
3. Open or reuse a tab
Control one visible tab with a stable tabKey instead of creating duplicates.
