The secure, self-hostable Zoom alternative
Zoom is the default for quick, reliable meetings. But it runs only on Zoom’s US-operated cloud, and its end-to-end encryption is an opt-in mode that turns off features. If your meetings are sensitive enough that where they run matters, Ollasync gives you the same one-click, no-download experience — on infrastructure you control.
Zoom is fast, familiar and scales enormously, and it does offer an optional end-to-end encryption mode for meetings. For most consumer and general-business calls, that’s plenty. The gap opens when you need to control where data lives and who operates the servers.

When Ollasync is the better fit
- You need meetings, recordings and documents to stay on infrastructure you operate — or fully air-gapped.
- You want end-to-end encrypted messaging that’s server-blind by default, not an optional toggle.
- You need a confidential deal room with live video, not just a call.
- You need a non-US operator or your own jurisdiction for data-sovereignty reasons.
Ollasync vs Zoom — FAQ
Is Ollasync a drop-in Zoom replacement?
For the core experience — one-click, no-download browser meetings with screen share, recording and chat — yes. Ollasync adds self-hosting, server-blind messaging and confidential deal rooms that Zoom’s cloud model doesn’t offer.
Does Zoom offer end-to-end encryption?
Yes — Zoom has an optional E2EE meeting mode (AES-256-GCM) that you enable per meeting, though it disables some features. It is not on by default, and Zoom still operates the cloud your meeting runs on. Ollasync lets you operate the servers yourself.
Can I self-host like Zoom?
Zoom is a cloud service; you can’t run it in your own datacenter. Ollasync is designed to be self-hosted — private cloud, on-premise or air-gapped — so data never leaves your control.
