How it works

Three primitives. One live session.

Every session is built on the same three primitives — stream the app, bring people in, then let code or the Copilot take over.

01

Stream

Low-latency, pixel-perfect delivery of any Windows app or full desktop straight into a browser tab. No client, no VPN, no RDP plugin — the app just appears.

02

Collaborate

Invite teammates into the same live session with shared cursor control. Pair on a legacy tool, walk a teammate through a workflow, or hand off control mid-session.

03

Automate

Click any element in the live UI tree to build a drag-and-drop automation, or hand the wheel to the AI Copilot and describe the task in plain English.

Built for developers

A session is just an object in your code.

Spin up a streamed Windows session from a single SDK call, hand it to the AI Copilot, or drive it directly against the live UI tree — no screen-scraping, no brittle image matching.

  • Python & JavaScript SDKs with first-class async support
  • Programmatic access to the live UI tree — find, click, read, type
  • Webhooks and events for every session lifecycle transition
  • Scoped API keys and short-lived session tokens by default

Every session records itself.

Full-fidelity replay of every session, plus friction metrics captured natively — hesitation, repeated clicks, dead-end paths — so you know exactly where a workflow or an automation breaks, without watching the whole thing back.

Questions developers ask first

Any Windows application or a full desktop — from a single .exe up to an entire session — rendered server-side and streamed to the browser as a low-latency pixel feed. Nothing about the app needs to change; if it runs on Windows, it streams as-is.
