What Is MiroTalk SFU?
MiroTalk SFU is an open-source, self-hosted WebRTC video conferencing platform that runs entirely in the browser. It's built as a Zoom alternative for anyone who wants to host their own meetings without downloads, plug-ins, or logins. The site describes it as "free browser based real-time video calls" with an SFU (Selective Forwarding Unit) server integrated, and claims unlimited conference rooms and users without call time limits. If you need a self-hosted meeting tool you can control, this is what it offers.
How it works
MiroTalk SFU uses WebRTC for real-time media and Mediasoup as its SFU. In an SFU architecture, each participant sends one stream to the server, and the server forwards it to the others — rather than every participant connecting directly to every other participant. That's what makes it scale better than a simple peer-to-peer mesh as meetings grow.
Because it's browser-based and WebRTC-native, there's nothing to install. The site states no download, plug-in, or login is required: you pick a room name and join.

Privacy and security
The site states that data stays between you and your participants, and that it doesn't collect or share personal information. Media streams are encrypted using SRTP (Secure Real-time Transport Protocol) via WebRTC. Because it's self-hosted, the deployment and data handling are under your control — which is the main reason people choose it over a hosted service.
When to choose it
MiroTalk SFU fits if you:
- Want a self-hosted alternative to Zoom or Google Meet
- Need browser-based meetings with no installs or accounts for participants
- Care about keeping meeting data on your own infrastructure
- Want an open-source platform you can extend via its REST API
It's less suited if you'd rather not run and maintain a server, or if you need a fully managed service with vendor support.
Getting started
The site's flow is minimal: pick a room name, join, and start talking, messaging, and sharing your screen. There are also options to customize a room and schedule a meeting. For a self-hosted setup, you'd deploy the platform on your own server — the project is open source, so the code and deployment details are available from the project itself.
Who's behind it
MiroTalk SFU is developed by Miroslav Pejic (Full Stack Developer). The project is sponsored by Recall.ai, an API for recording Zoom, Google Meet, Microsoft Teams, and in-person meetings.
