# Supported Browsers

Coresee runs entirely in your browser — there's nothing to install to join a room. Because video, audio, and screen sharing all depend on capabilities built into the browser itself, Coresee checks your browser when you open a room and will let you know if something's missing.

For the best experience — including camera and microphone previews, screen sharing, and audio device selection — use the latest version of a supported browser and keep it up to date. Older or less common browsers may not have the features Coresee needs and won't be able to join a room.

<Info>
  **Always use the latest version.** Coresee relies on current web standards for real-time video and audio. Running an outdated version of a supported browser can produce the same errors as using an unsupported one — check for browser updates if you run into trouble joining.

## **Other ways to join**

If you'd rather not join through a browser tab, Coresee also offers a desktop application.

### **Coresee desktop app**

The desktop app is a standalone application for Windows and macOS. It supports the same core meeting experience as the browser, plus a few desktop-only capabilities such as native screen-share pickers and, where applicable, NDI/SDI capture-card workflows. If you're on a supported browser, joining from a browser tab and joining from the desktop app both work equally well — use whichever is more convenient.

### **Mobile**

On phones and tablets, join using Safari (iOS/iPadOS) or Chrome (Android). The in-room experience adapts automatically to a smaller screen — some controls move into an overflow menu to keep the layout usable.

## **If your browser isn't supported**

Coresee checks browser compatibility as soon as you try to open a room.

This means the browser you're using is missing a capability Coresee needs to run a video session — most commonly because it's an unsupported browser entirely, or a very old version of one. The room won't open until you switch.

To resolve it:

* Switch to one of the supported browsers listed above.
* If you're already using a supported browser, update it to the latest version and try again.
* If you're on a work or managed device, an older forced browser version may be the cause — check with your IT team.

## **Troubleshooting**

A few other things worth checking if a room isn't behaving as expected.

### **Camera or microphone not showing up**

This is usually a permissions issue rather than a browser-support issue — the browser is blocking Coresee's access to your devices. See the camera and microphone permissions article for how to check and reset those settings for your browser.

### **Everything looks fine but audio/video won't connect**

Some corporate or school networks restrict the kind of real-time connections Coresee uses. If you're on a supported, up-to-date browser and still can't connect, try a different network (like personal hotspot) to confirm whether the network is the cause before assuming it's a browser problem.

<Warning>
  **Still stuck?** Contact your host or reach out to [Coresee support](help@coresee.com) with the browser name and version you're using — that's the fastest way for us to identify what's going wrong.
