We compare neither picture quality nor ease of use: those are settled by trying, not in a table. Only public characteristics, each with a link to the vendor's own documentation.

Every claim links to its source.
A comparison that concedes nothing does not read like a comparison. Here is what each solution does better than us, and where we part ways.
Picture quality and network resilience remain market references, and the integration ecosystem is the richest of the lot.
Zoom does offer an on-site deployment, the Meeting Connector, but the service rests on an American company subject to the CLOUD Act. Billing is per host licence, as with us; the code, however, cannot be audited.
A sovereign alternative to Zoom and TeamsIntegration with the rest of the Microsoft suite is unbeatable if your organisation already lives there.
There is no version of Teams you can install on your own servers, as Microsoft states in its own documentation. Video conferencing arrives through a global office licence, which makes its real cost hard to isolate.
A sovereign alternative to Zoom and TeamsA mature project, deeply established in education, with a community active for more than fifteen years.
The vendor is Canadian and the install calls for a noticeably larger machine. Our compatibility API accepts BigBlueButton calls: a Moodle configured for BBB points at Vuisio with no change on the LMS side.
Vuisio next to BigBlueButtonSimple to install, permissive Apache 2.0 licence, and an account-free experience that did a great deal for open video conferencing.
The project has belonged to 8x8, an American company, since 2018, and its hosted service runs in the United States. The videobridge also asks for more resources than our Rust core.
Vuisio next to JitsiA table is only as good as its columns. Here is why each one is there, and what it changes for you.
This is the criterion that opens or closes a public tender. Hosting outside the European Union, or by a company subject to extraterritorial law, counts as a transfer and has to be documented.
The vendor's address does not settle it. A solution can be published outside the United States and still rest on an American media server: BigBlueButton, a Canadian project, ships LiveKit, published in California. The question is not only where the seller sits, but who writes the code that carries your streams, and under which jurisdiction it lives.
Without access to the code, a confidentiality promise stays a promise. With it, your technical team or a third party can verify what the software does, and you no longer depend on the vendor surviving.
This is what separates a supplier from a dependency you cannot leave. If your data must never leave your walls, this line decides on its own.
The real cost of a self-hosted solution is the machine that runs it, every month. A factor of four on the requirements is a factor of four on the infrastructure bill.
If your Moodle, intranet or Nextcloud already speaks to BigBlueButton, a compatible API saves reconfiguring everything. That is often the difference between a one-day migration and a six-month project.
Billing per participant makes the budget unpredictable: the better a meeting does, the more it costs. Billing per host makes it calculable before the first month.
What a comparison leaves out says as much as what it includes. We would rather name it ourselves.
They depend on your connection, your machines and the number of participants. No measurement a vendor makes on its own servers transfers to yours. Fifteen minutes of trying settles it.
That is subjective, and rightly so. An interface that suits a technical team can lose a non-profit's general assembly.
Zoom and Teams have ecosystems we do not match. If your organisation depends on one specific integration, check that before anything else.
We have no paying customers yet and we will not pretend otherwise. Comparing market share would work against us, and it is not what makes a tool right for your needs.
A comparison published by a vendor is judge and party. The only way to make it useful is to make it verifiable line by line.
If you find a line that is wrong, write to us: we will fix it and the survey date will change. That is more useful to us than a flattering table.
Open a room, invite three people, judge for yourself. It is free, with nothing to install and no card required.
