For more whiteboard-focused teaching approaches (particularly if you’d like to upload files to collaborate on), check out Koala Go or DingTalk. If you want something that is essentially a Zoom copy, then check out VooV or AnyMeeting, whereas if you teach conversation-focused classes then Skype could be a good lightweight option. Overall, we’d argue that Koala Go is the best option out there for most online ESL teachers, particularly if you are focusing on teaching kids – their fun platform, rewards system and interactive tools are really child-friendly! It’s also one to consider as a paid option, with their pro plan priced competitively with Zoom but with much more useful features. One aspect unique to Zoom is that it takes advantage of dual screens, whereas Teams and Meet don't.So which is the best free Zoom alternative? I would classify Zoom, Teams and Meet in this order, both having a good quality of image and sound (but no original sound). Also Teams or Zoom might be provided by your company or school. If you have Office 365, I think you already have it automatically and can do unlimited sessions without paying anything more.

Microsoft Teams: Now that it has replaced Skype in the mind of its developers, it has become more and more available.

Google Meet: According to their website, it is either unlimited for 2 participants and limited to 1 hour for more participants, or totally free (it depends on which page you look at and maybe on which country you live in). Other solutions (apart from paying or restarting your meeting every 40 minutes):

Sometimes I felt all participants were physically in my room whereas other times I felt they were lost at the end of the world, like if I were listening on a distant AM radio station when there is a thunderstorm. I used Skype before the pandemic, which is light years ago! When it works, it's great, but the quality was very uneven.
