Open-source Adobe Connect alternatives

Jitsi Meet is a collection of open-source projects for hosting video conferences. It works in all current browsers and has Android and iOS apps, and it can be used as a ready-made service or embedded into other web applications through web and native SDKs. It is built on WebRTC with a selective forwarding unit to scale to larger meetings.

Meetings offer HD audio and video, content sharing, raised hands and reactions, chat with private conversations, polls and virtual backgrounds. The hosted service at meet.jit.si is free to use, and the README says you can start a meeting after signing in with an account from a major provider. Mobile users can use the browser or the full-featured apps, which are also available from F-Droid, and open beta programs let early adopters test features.

If you prefer control over your data, Jitsi can be deployed on your own infrastructure, with documentation for running your own instance. Jitsi Meet is Apache-2.0 licensed and written in TypeScript. It suits organizations, schools and communities that want an alternative to proprietary meeting software.

BigBlueButton is an open-source web conferencing system designed for online learning, intended to help teachers teach and learners learn. Participants can share audio, video, slides (with whiteboard annotations), chat messages and their screen in real time, and can also be used for many other meeting types beyond education.

To keep remote students involved, instructors can use polls, emoji reactions, whiteboards that several people can draw on, shared notes and breakout rooms. During a session it generates analytics shown to moderators on a Learning Analytics Dashboard, and presenters can record sessions for later playback and sharing. The README lists online tutoring, flipped classrooms, group collaboration and online classes as the educational scenarios it was built for. Its topics reference WebRTC.

The current major release is BigBlueButton 3.0, which can be installed on Ubuntu 22.04 with the bbb-install.sh script, and full documentation covers architecture, features, the API and GreenLight, the default front end. The software is licensed under LGPL-3.0, while the name and logo are trademarks of BigBlueButton Inc. It suits schools, universities and training providers that want to host their own conferencing.

edumeet is a multiparty web meeting service built with mediasoup and WebRTC, with a React front end. People join meetings in the browser, sharing microphone, camera and an additional video stream, and the system is aimed at education and organizations that want to host their own conferencing.

Main features include audio and video streaming, screen sharing, file sharing using a torrent-based approach, text chat and optional local recording that is disabled by default. Authentication supports OIDC, SAML and a local database. The release is delivered as Docker images for the client, room server, media node and management server, with an installation script that sets up domains, certificates and services.

Hosting it needs Docker and docker-compose, curl, a public IP address and two domain names, one for the service and one for the TURN server, with ports 80 and 443 open. edumeet is licensed under MIT and the project offers a public instance for trying it online and a Discord community. It suits universities, research networks and other institutions that prefer self-hosted video meetings.

Plug-N-Meet is an open-source web conferencing system built on the WebRTC infrastructure of LiveKit, written in Go. It is designed to be scalable and easy to customize so that a self-hosted video conferencing experience can be integrated into any existing website, application or system.

Collaboration tools include HD audio and video, screen sharing, virtual backgrounds, a collaborative whiteboard with office file support for PDF, DOCX and PPTX, a shared notepad, polls and breakout rooms. Adaptive streaming uses simulcast and dynacast with H264, VP8, VP9 and AV1 codecs to keep calls stable on poor networks. WebRTC encryption is on by default, with optional end-to-end encryption for media and data channels, and a SIP gateway lets participants join the audio by phone. An AI agent adds live spoken translation, real-time transcription and automated summaries with action items, available through an Artifacts API.

Integration is done through an API and SDKs, including one for PHP, and webhooks. Plug-N-Meet is licensed under MIT and has a developer community on Discord.
