That’s a pretty honest website name as this site will never charge you for using their service. Instead, they rely on donations and their users’ goodwill to sustain their business. Even as a free app, it is incredibly fully featured as it allows up to 1,000 participants in a meeting, and even has the recording, Whiteboarding, screen sharing, and regular chat options.
The only downside of this site is that it is a bit more complicated and less appealing than the others previously mentioned. Still, if you can bear a bit of effort and the growing pains of learning how to use it, freeconferencecall.com is a pretty amazing tool to use, considering that one pays nothing for it.
An alternative to the G Suite lineup is the Microsoft Teams that also comes with other apps you might find useful.
Microsoft Teams, like Google Meet, is a decently featured conferencing app that comes with Microsoft 365, currently priced at 7 USD a month. The great difference is that instead of it coming with Google Docs, Google Slides, and Google Sheets, you would instead get fully licensed and featured versions of Microsoft Word, Microsoft Powerpoint, and Microsoft Excel. If you are more accustomed to using this app ecosystem, then this might be a better choice for you.
