Technical Requirements to Use Livestorm

Is Livestorm compatible with every browser?

Yes. Your attendees will be able to join your webinar on all major browsers including IE10+, Safari, Firefox, Opera and Google Chrome.

However, as a host, you must use Google Chrome to share your webcam and screen. The same goes for anyone that you invite on stage to share their screen, webcam, or audio.

Also, note that attendees who are not on Google Chrome, Firefox, Opera or on any mobile/tablet device  will experience a 15 seconds delay due to browsers limitations.

Does Livestorm work on mobile/tablet devices?

Yes, Livestorm is optimized to work on mobile/tablet devices including iPhone, iPad and Android devices. But, again, as a host, you will have to be on a desktop computer with Google Chrome, Firefox, or Opera.

We do not provide a mobile app for one simple reason: everything works on your browser on desktop or mobile.  Livestorm  is responsive so it supports small screens as well. However, attendees on mobile will experience a 10-15s delay.

What are the connectivity requirements to host or access a webinar?

As a host,  we recommend 15Mb/s up and down for optimal results. A minimum of 5Mbs/s if necessary to upload your live stream. Aim for 5Mb/s for attendees.  Livestorm  will downgrade your video quality and give priority to audio if you don't have enough bandwidth. Run tests here.

This is a test from our offices, we have a pretty good download speed. Our upload speed is good but not incredible, enough to send a good video stream.

Your c onnection speed is not the only factor. You have to also look for connection stability aka the number of people connected to that same connection. The connection stability will impact the number of packets lost during a live session. Therefore, try to use Ethernet over Wifi and ask your team to not saturate the network.

Livestorm works on every network, even if you are behind a firewall. However:

As an attendee:

As a host:

  • Run tests here: and send us the results to
  • If the video starts loading after a while, your router might be blocking the video stream. Ask your IT to unblock web sockets, the 443 ports for video streaming and the WebRTC protocol.

Tip: Don't forget to pause your Google Drive sync or any other bandwidth consuming apps during your webinar.
