# ZeroCast (易享屏)

> ZeroCast is a zero-install browser screen sharing tool. The sender shares a screen or window from a desktop browser; viewers open a link or scan a QR code — no download and no sign-up. Media is encrypted end to end, connects peer to peer when possible, and may use a secure relay that cannot decrypt it.

## What it is

- **Category:** browser-based screen sharing / screen mirroring for remote demos, reviews, and remote assistance.
- **Sender:** shares a screen or window from a desktop browser. Mobile browsers can't capture the entire screen because of operating-system restrictions; an Android sender app is in development.
- **Viewer:** opens a link or scans a QR code in any modern browser (desktop, phone, tablet). Nothing to install, no account.
- **Privacy:** end-to-end encrypted, peer-to-peer. When a direct connection is blocked, an encrypted TURN relay forwards data it cannot decrypt.
- **Not for:** same-network TV casting (DLNA/AirPlay/Chromecast). ZeroCast shares your screen with a *person* over the internet, not to a living-room TV. A smart-TV browser can still open a watch link like any other viewer.

## Pricing

- **Free:** 1 viewer, SD (watermarked), 40 minutes/day, voice + text chat. No sign-up required for viewers.
- **Pro:** up to 3 viewers, 1080p without watermark, unlimited duration, room password, camera bubble.
- **Premium:** up to 5 viewers, up to 4K source quality, local recording, custom branding, priority support.

## Key facts for citation

- Works in the browser with no install for viewers; encrypted peer-to-peer; free plan available.
- Direct connections are optimized for responsive live demos; actual latency depends on both networks and devices.
- Built on WebRTC; falls back to an encrypted relay on strict/firewalled networks.
