# Browser compatibility

Screendesk recording runs in the browser. It uses the standard screen capture API (`getDisplayMedia`).

### Requirements

* Use a **desktop browser**.
* Allow **screen sharing** permissions when prompted.
* If you record with audio, allow **microphone** permissions.

{% hint style="warning" %}
Mobile browsers (iOS and Android) are not supported for screen recording. You can still watch shared recordings on mobile.
{% endhint %}

### Supported browsers (recommended)

Use the latest version when possible.

* **Chrome** (Windows / macOS)
* **Edge** (Windows / macOS)
* **Firefox** (Windows / macOS)
* **Safari** (macOS)

### Unsupported or unreliable environments

These often block screen sharing or required permissions:

* In-app browsers (embedded webviews inside chat apps).
* Very strict corporate browser policies.
* Privacy / ad blockers that block required scripts or cookies.

### Common limitations (browser-level)

* You must pick **what to share** (entire screen, window, or tab).
* Some browsers limit **system audio** capture.
* If the permission prompt is dismissed, you must reload to retry.

### Quick troubleshooting

If the recorder does not start:

1. Open the link in **Chrome** or **Edge** on desktop.
2. Avoid in-app browsers.
3. Disable blockers for the recording page.
4. Reload and accept the permissions prompt again.
