Just to add: Teams does a lot more than video calls and chat, it is basically the most cross-integrated M365 app. These alternatives better have really good calendar integrations because for most users that is a basic requirement.

Thanks for your feedback!

However, MiroTalk in addition to being open-source, has many features that are not just video calls and chats, below I list all the repos where you can see, more or less, the features it offers:

MiroTalk P2P: https://github.com/miroslavpejic85/mirotalk

MiroTalk SFU: https://github.com/miroslavpejic85/mirotalksfu

MiroTalk C2C (new): https://github.com/miroslavpejic85/mirotalkc2c

MiroTalk WEB (new): https://github.com/miroslavpejic85/mirotalkwebrtc

There are features like Alexa, in the SFU version, where you can interact with the app vocally, giving it commands such as: open the chat, send messages, send files, and so on...

Obviously MiroTalk can be improved and can grow further, I'm just giving a chance to not depend on Zoom, Teams, Google Meet ... and have something of your own, that you can customizable, To run in the cloud, in your local PC (exposing on HTTPS with ngrok: docs/ngrok.md) or in your own dedicated server (following the documentation: docs/self-hosting.md)

In addition, being a PWA (progressive web app: https://www.youtube.com/watch?v=Z8MjdQGyjfA&ab_channel=Women...) it doesn't need a native app, it lives in any browser and works in any mobile or desktop devices :)
