Open-source Stream alternatives

LiveKit is an open-source platform for realtime audio, video and data, aimed at developers building voice, video and AI agent applications. This repository holds the LiveKit server, a distributed WebRTC selective forwarding unit (SFU) written in Go on top of the Pion WebRTC implementation.

People, devices and AI agents join the same room as participants, and agents can be dispatched into rooms automatically or on demand. The server offers speaker detection, simulcast and selective subscription, uses JWT for authentication, and handles UDP, TCP and TURN connectivity. SDKs cover web, mobile, desktop, embedded and server environments, and a separate Agents framework in Python and Node.js supports code-first voice agents.

The server ships as a single binary and can be deployed with Docker or Kubernetes on your own infrastructure under the Apache 2.0 license. The vendor also runs LiveKit Cloud, a managed service that handles deployment and observability.

OpenIM is an open-source instant messaging solution aimed at developers rather than end users. The project contrasts itself with standalone chat apps such as Telegram, Signal and Rocket.Chat, saying it is a set of building blocks for adding messaging to your own application instead of an installable chat product.

It consists of the OpenIM SDK, a client-side library, and the OpenIM Server, written in Go. Together they handle sending and receiving messages, managing users and managing groups, so teams can embed chat into social, marketplace, enterprise or other apps without building the infrastructure themselves. The README is translated into many languages and links to community channels on Twitter, Slack and WeChat, and topics mention IM, chat and messaging.

OpenIM is Apache-2.0 licensed and runs on your own servers. It suits product teams and agencies who need to own their messaging stack, for example for data-residency or customization reasons, and who are comfortable operating a Go back end.

WuKongIM is open-source messaging infrastructure that you build your own product on. It takes care of client connections, storing and syncing messages, presence and delivery to online users, while your application keeps ownership of the user interface, accounts and business rules.

The project suits personal and group chat, customer support, application notifications and streaming AI replies. A key design point is a self-contained messaging core with built-in storage and clustering, so no external database, cache or message queue is required. The repository offers a quick start, a live demo, a showcase and documentation, and the README is available in Chinese as well as English. It is written in Go.

WuKongIM is licensed under Apache-2.0 and runs on your own servers, which suits teams that want to embed chat in their apps without depending on a third-party messaging service or running extra infrastructure.

JuggleIM is a high-performance, scalable instant messaging backend that you host yourself. It is built on a Protobuf and WebSocket long-connection protocol and focuses on efficient message delivery and reliable storage, so teams can add chat to an app, website or business system quickly.

The server supports private chat, group chat and chatrooms, exposes WebSocket and REST APIs, and offers multi-tenant operation, with SDKs for client platforms. It is positioned for social products, customer-service systems and similar use cases. Documentation includes a quick deploy guide, an API reference and an introduction, and the code is written in Go.

JuggleIM is licensed under Apache-2.0 and deployed on your own servers, which keeps message data in your control. It suits product teams that need to embed real-time messaging without relying on a third-party chat service.

ODeck is an open-source tool for streamers and productivity users that works like a Stream Deck, with your phone acting as the key panel. It lets you give new purpose to an old, neglected smartphone and use it to trigger actions on your computer.

You create custom devices on the desktop app with your own number of keys vertically and horizontally, then pair the phone by scanning a QR code. Each key can be customized individually with background color, label text color, background images, or hidden labels to show only an image. The desktop app is available for Windows and Mac and the mobile app for Android and iOS.

ODeck is built with Electron, React, React Native and Socket.io, released under MIT, and its latest release listed is v0.0.8, so it is still early stage. The README is available in English, Portuguese and Spanish.
