Overview
MiroTalk SFU is the scalable group-conferencing edition of the open-source MiroTalk WebRTC project, built on a Selective Forwarding Unit (SFU) architecture using the mediasoup library rather than direct peer-to-peer connections.
This server-mediated design lets it support unlimited concurrent rooms and far more participants per meeting than the peer-to-peer MiroTalk P2P edition, positioning it as a self-hosted, open-source alternative to Zoom, Google Meet, and Microsoft Teams for larger conferences and webinars.
Key Features
The platform offers webcam and screen sharing up to 8K at 60fps with echo cancellation and noise suppression, an interactive whiteboard, integrated chat, file sharing, and meeting recording, all running in the browser with no downloads or plugins.
More advanced capabilities aimed at events and broadcasting include RTMP streaming to external platforms, virtual backgrounds, ChatGPT integration, and AI avatars for participants.
Pricing
MiroTalk SFU is free and open source under the AGPLv3 license, allowing anyone to self-host it on their own server infrastructure at no licensing cost.
For teams that want alternative licensing terms outside AGPLv3's copyleft obligations, a commercial license has also been offered through third-party marketplaces such as CodeCanyon as a one-time purchase that includes full source code and lifetime updates.
Key Features
SFU (mediasoup) architecture — Media streams are relayed through a central server rather than connecting every participant directly, enabling much larger meetings than pure P2P.
Unlimited rooms and participants — No hard cap on concurrent rooms or call duration, suited to webinars and larger group conferences.
8K/60fps screen and webcam sharing — High-resolution video and screen sharing with echo cancellation and noise suppression.
RTMP streaming — Broadcast meetings out to external platforms via RTMP for larger audiences.
AI avatars and ChatGPT integration — Built-in AI features including avatars and ChatGPT integration for meetings.
Collaborative whiteboard — Real-time shared whiteboard for group brainstorming and explanation.
Meeting recording — Record screen, webcam, and audio directly from the browser.
Self-hosted deployment — Full source code and Docker-based install scripts for deploying on your own cloud server.
