Videoconferencing is a way to connect multiple distributed parties via global communication networks to allow for video and audio exchanges between multiple parties simultaneously. This article is to describe what cross-platform software is currently available for cheap or free and their capabilities.

Comparison of Web Conferencing Software

WebRTC Open Source

WebRTC is a standard protocol for encrypted video communication whose API is implemented in many open source browsers, such as Mozilla Firefox. There's a few open source software products that utilize Web RTC without requiring the installation of software other than the web browser (no addons needed). Many WebRTC-backed websites utilize proprietary software. Here's some that don't:

Jitsi Meet

NodeJS powered scalable website whose sourcecode can be downloaded to run on your own apache webserver. Utilizes Jitsi Videobridge with WebRTC & SFU for scalability

A live version of jitsi meet hosted by Atlassian (the company that owns BlueJimp, the original developer of Jitsi software projects) can be accessed at

Atlassian, who acquired BlueJimp in 2015 (the company that built the most mature, open-source SFU, Jitsi Videobridge), produces many not-free, closed-source software products. Atlassian continues to develop the Jitsi open-source software.

Atlassian gives free licenses to nonprofits for their closed-source products, such as Hipchat.

Hipchat advertises that they can support up to 20 people in a vidoeconference.

Atlassian is also responsible for hosting the free Jitsi Meet site that OSE uses frequently at
