Remote support: see a customer's screen in the browser

When a customer cannot describe an error or find a setting, seeing their screen is often enough to explain the next step. ZeroCast's invitation flow lets them share from a desktop browser while the support person watches, with no customer installation or account.

What you need to know

The support person signs in and creates an invitation. The customer opens that invitation on a computer, clicks Share my screen and chooses a window in the browser picker. This is attended visual assistance: the customer remains in control and performs the actions. ZeroCast does not provide remote mouse, keyboard or unattended access.

Step-by-step setup

1

Create an invitation

Sign in to ZeroCast, open Invite someone to share their screen and copy the invitation text. Keep the invitation console open to receive the customer's stream.

2

Prepare the customer

Send the invitation through your existing support conversation. Ask the customer to use a desktop browser, close private information and open the app window related to the issue.

3

Get explicit screen permission

The customer opens the link, clicks Share my screen and selects the relevant window. They do not need to register. Nothing is captured until they approve the browser picker.

4

Guide and finish

Watch the screen while the customer reproduces the issue. Use an existing call or enable the in-session microphone or text chat to explain actions. Ask them to stop sharing when finished, then end the invitation from the console.

Compatibility and troubleshooting

This flow cannot capture an entire phone screen from a mobile browser. For a desktop customer who cannot start capture, check browser and system screen-recording permissions. If the connection stalls, confirm both pages remain open and retry on a permitted network. A TURN relay can help with restricted networks, but company policies may still prevent sharing.

Privacy and session limits

Ask the customer to share only the relevant window and stop before entering credentials or payment details. The customer's own casting plan and allowance apply: normal and invited casting share the screen sharer's daily quota. The support person's paid plan does not automatically upgrade the customer. Screen media is encrypted and not stored by ZeroCast; a viewer can still take screenshots.

When this is useful

  • ✓ Help a customer locate a setting or understand an error message.
  • ✓ Walk a colleague through a web form while they enter their own information.
  • ✓ Observe a reproducible issue without installing a remote desktop agent.

Visual assistance versus remote desktop control

A browser invitation is suitable when the customer can click and type but needs guidance. It avoids asking them to install a remote desktop agent and lets them choose the visible window.

If support must operate the computer, transfer files or reconnect while nobody is present, use a tool designed for those requirements. ZeroCast cannot control the customer's operating system or silently reconnect to a stopped screen capture.

Frequently asked questions

Who needs an account?

The support person creating the invitation must sign in. The customer can open the invitation and share as a guest within the guest daily allowance.

Can I click or type on the customer's computer?

No. You see the chosen screen or window and explain what to do. The customer performs the actions and can stop sharing at any time.

Can I help a customer on a phone?

This workflow requires a desktop browser to send the screen. A phone can watch a demonstration, but cannot share its entire device screen through the browser invitation.

Can the customer pause to enter a password?

They can stop sharing before entering sensitive information and share again after finishing. The invitation console can wait for them while the invitation remains open.
