Zulip is an open-source team chat server and web application built around topic-based threads. Messages stay grouped by subject, helping teams combine real-time discussion with asynchronous work without losing the surrounding context. The project is used by remote teams and open-source communities, and organizations can try the public development chat or follow the documentation to run their own service.

Element provides a Matrix client for web browsers and desktop operating systems. People can use the hosted application, self-host an Element Web instance, or install the Electron-based desktop build. Its primary support covers recent desktop versions of Chrome, Firefox, Edge, and Safari, plus the official desktop client on actively supported macOS, Windows, and Linux releases.

LlamaGPT provides a self-hosted, ChatGPT-style web interface backed by Llama 2 or Code Llama models, keeping conversations on the device. It can be installed from the umbrelOS app store or run on Apple Silicon, general Docker hosts, and Kubernetes. Model downloads and memory requirements vary considerably, and the current setup supports a fixed list of models rather than arbitrary custom models.

MiroTalk SFU lets organizations run browser-based video conferencing and real-time collaboration on infrastructure they control. Its mediasoup-based selective forwarding architecture is designed for multi-participant rooms and streaming-oriented use cases, while a REST API supports integration with other systems. The self-hosted model keeps meeting data and deployment choices under the operator's control. It is therefore best suited to teams prepared to configure, secure, monitor, and scale their own server rather than those seeking a fully managed meeting service.
