Stream and automate
any Windows UI, instantly.
Onscryn is a zero-client streaming layer for Windows apps and desktops — no VPN, no installer, no RDP gateway. Bring an AI Copilot and a visual workflow builder to click, script, and automate the live UI tree.
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.
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.
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.
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.
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

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.
Trusted by developers shipping Windows automation into production — from indie RPA tooling to internal ops platforms at growing startups.
