Open-source Webex alternatives

Rocket.Chat is a communications platform written in TypeScript for teams and organizations that care about data protection. It supports real-time conversations between colleagues, with partner companies, and with customers or citizens, and its topics place it in the same space as Slack, with WebRTC for calls and meetings.

The product emphasizes control over where and how it runs. Deployment options include self-hosted servers, a managed cloud and fully air-gapped environments, with a scalable architecture and performance monitoring for workspace administration. Security and sovereignty features, including identity management, are a core part of the pitch, and the platform is built to be highly customizable, so organizations can adapt it to their own workflows and integrations.

The repository's license is listed as 'Other' on GitHub, although the topics reference an MIT-licensed community core, so confirm which components fall under which terms before relying on it commercially. It suits government bodies, enterprises and regulated industries that want a Slack-style tool they can host themselves.

Mattermost is an open-core collaboration platform you host yourself, covering team chat, workflow automation, voice calls, screen sharing and AI integrations. This repository is the primary source for core development of the platform. The server is built with Go and React, ships as one Linux binary and depends on PostgreSQL. GitHub lists the license as 'Other'.

Each month, on the 16th, a newly compiled release is published under the MIT license. You can deploy Mattermost on-premises or try it in the cloud. The project highlights use cases such as DevSecOps, incident resolution and IT service desk, and it offers native clients for Android, iOS, Windows, macOS and Linux in addition to the web interface.

Installation options include Docker, Ubuntu, a tar archive, Kubernetes, Helm and an Omnibus package. Developers can build integrations through APIs, webhooks, slash commands, Apps and plugins, and the repository links product and developer documentation, security bulletins and contribution guides. It suits engineering, security and operations teams that want controlled, self-managed team messaging.

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.

Element Web is a client for Matrix, the open protocol for decentralized messaging. It is the web and desktop application formerly known as Vector and Riot, and it lets people join rooms, chat in teams and communities, and collaborate across Matrix servers rather than inside a single vendor's network.

The client is built with TypeScript on top of the Matrix JS SDK. The README defines support tiers for browsers, covering recent versions of Chrome, Firefox, Edge and Safari on desktop, best-effort handling for ESR and extended-stable releases, and community support for mobile web. For phones and tablets the maintainers recommend the native Element X apps for Android and iOS.

It is released under the AGPL-3.0 license and is typically served from your own web host or used through the hosted app from the vendor, Element. Related products such as Element Call and the Enterprise Server Suite are mentioned as part of the wider Element offering. Changes are tracked on GitHub with regular release cycles.

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.

MiroTalk P2P is an open-source video conferencing platform that uses direct peer-to-peer WebRTC connections between participants. You host it on your own server, and people join meeting rooms from a browser with no downloads and no time limits. It is meant for teams and communities that want private real-time communication they control.

Features include unlimited rooms, screen sharing, text chat, a collaborative whiteboard, recording and general collaboration tools. It works across common browsers and platforms, can be deployed with a Docker image in minutes, and has a live demo, documentation and a Discord community. The software is JavaScript based.

MiroTalk P2P is licensed under AGPL-3.0. Because media flows peer to peer, it keeps traffic off a central media server, which suits small groups. It fits small teams, schools and communities who want a self-hosted alternative to commercial meeting tools.

MiroTalk SFU is an open-source video conferencing platform that you deploy on your own server. It uses a mediasoup selective forwarding unit to scale real-time audio and video, and is offered as an alternative to Zoom, Google Meet, Jitsi Meet, and Microsoft Teams. It is released under the AGPL-3.0 license, and one-time commercial license fees are also available.

The platform supports video chat, screen sharing, file sharing, live streaming through RTMP, and webinar-style use cases, with real-time communication over WebRTC and WebSocket. Compared with the hosted services it replaces, the README highlights unlimited meeting duration and rooms, and full control of data and infrastructure with no vendor lock-in.

It is built on Node.js and is distributed with Docker support, so you can run it on a VPS or internal server. It suits organizations, communities, and developers who want private meetings and need to embed or customize video calls, and who are comfortable operating the media server themselves.

La Suite Meet is an open-source video conferencing application built with Django and React and powered by LiveKit. It runs in the browser, so participants join calls without installing anything. The code is released under the MIT license and is fully self-hostable. It comes from the French government's digital suite project, and a public instance runs at visio.numerique.gouv.fr.

Features include stability tuned for large meetings, multiple screen sharing streams, a non-persistent secure chat, meeting recording, transcription and summaries (currently in beta), telephony integration, authentication and access control, and a customizable front end. End-to-end encryption is listed as coming soon. LiveKit contributes speaker detection, simulcast, selective subscription, and SVC codecs.

The project has a Matrix channel where the team answers questions and helps with deployment. It suits public institutions, companies, and communities that want a sovereign, self-hosted alternative to commercial conferencing services and are prepared to operate the media infrastructure.

Galene is a videoconferencing system that aims to be easy to deploy and to run on very moderate server resources. It is a WebRTC-based SFU, meaning the server forwards participants' media streams to each other instead of mixing them, which keeps CPU use low while supporting group calls from a web browser.

Beyond video calls it supports file sharing, as its topics indicate, and ships with documentation covering installation, usage and administration, writing clients, the client protocol and an administrative API. People join through a browser, and the quick start explains how to try it locally with a self-signed certificate. Questions and common issues are answered on the project website.

Galene is written in Go by Juliusz Chroboczek and is licensed under MIT. You run it on your own server, which suits universities, small organizations and groups that want a private conferencing system without a large infrastructure. Discussion and patches go through a mailing list, though pull requests on GitHub are also accepted.

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.
