🆕 Software Suggestion | Kopano & Kopano Meet

[Raviu56]

Basic Information

Name: Kopano & Kopano Meet Category: Collaborative platform & secure p2p video conferencing URL: https://kopano.io/ & https://meet-app.io

Description

Kopano 100% Open source collaboration tools: email, calendaring, Mattermost chat, webRTC video meetings, document collaboration with LibreOffice Online, integration with file storage services and more.

Kopano Meet is a secure, open-source and easy-to-use solution for video conferencing. It is peer-to-peer and end-to-end encrypted which means that a conversation always takes place directly between the people in the call, with no other parties in between. Kopano Meet was developed as a progressive web app so interaction with Meet feels exactly the same, no matter the device that is used.

Why I am making the suggestion

I could see it's useful alternative to other tools in the current pandemic, people depends on zoom and such commercial bad acting services. It's also included in latest openSuSE leap release. Could be self hosted.

My connection with the software

• [ Y ] I will keep the issue up-to-date if something I have said changes or I remember a connection with the software. I'll try to. But I indeed have no connection.

I would be a bit suspicious towards Mattermost, but maybe with a warning and for small private groups it could be ok. https://github.com/mattermost/mattermost-server/issues/6320

~I don't think the suite is "100% opensource", from what I gather it's only some components to interact with Kopano's suite of web apps that are:~ https://stash.kopano.io/projects

~For example, I could not find the source code for Kopano Meet.~

My bad, I found Kopano Meet's source code, licensed under AGPLv3: https://stash.kopano.io/projects/KWM/repos/meet/browse

Documentation for Kopano Meet: https://documentation.kopano.io/kopano_meet_manual/installation.html

I focus on Meet because instant messenger and video calls are a keen interest of mine, as they are a particularly difficult and demanded use case nowadays ;-)

Ok so Kopano Meet seems very interesting, it does what Jitsi Meet should by directly connecting the peers together and end-to-end encrypting all communications, without decrypting on server. In fact, they clearly state that communications never go through the server, it's all through WebRTC. I think it's a worthy addition, at first as a "Worth Mentioning" at first but if we can gather more infos and it gets more established then it could potentially become a recommendation.

@Raviu56 do you have any info about what kind of encryption is used more technically? We can likely find from the source code otherwise although more cumbersome (this info is not in the readme).

Also, they claim that the app supports an unlimited amount of participants, in the free version. Contrary to, surprisingly, their starting paid plan which only allows for about 500 users max. I guess this is because the free version uses peer-to-peer only, so that their server does not get overloaded like Jitsi Meet can, and so the only limitation is whether the participants have an internet bandwidth large enough to sustain the streams from a number of participants. The paid plans offer a Jitsi Meet-like system with a server in the middle to balance the load.

So this adds additional credence to the statement that Kopano Meet is by default fully P2P. I would be very curious to see how well it performs with say 50 or 100 participants, something that Jitsi Meet struggles with. If Kopano Meet sustains this kind of load, it could be very useful for academic meetings.

About the Kopano "office" suite, it seems very nice for teams, but it seems complex to setup, it seems necessary to self-host or buy their subscription, I can't see a free mode (please correct me if I'm wrong).
