Frequently Asked Questions
? Is Janus hard to install?
Janus offers official Docker images for easy deployment, but configuring plugins and integrating a frontend requires basic knowledge of WebRTC and server management. Pre-configured setups can simplify this for less technical users.
? Is it a good alternative to Zoom?
Janus is a backend gateway, not a turnkey Zoom alternative. It powers custom video conferencing solutions—pair it with a frontend (e.g., using the Video Room plugin) to build a self-hosted alternative with full data control.
? Is it completely free?
Yes! Janus is open-source under the MIT license, so it’s free to use, modify, and self-host without any subscription fees or hidden costs.
