Open Source TypeScript Live Streaming Software

Owncast is a free and open source live video and web chat server for use with existing popular broadcasting software. Have complete control and ownership over your stream, allowing you to create the content and community you want. The frictionless built-in chat allows your viewers to be a part of the action. Include custom emotes and build chat bots to encourage engagement from your viewers. Point your existing broadcasting software at your Owncast server and begin streaming. Owncast can work with different storage providers to optionally scale your videos to many viewers using only low-powered hardware. Owncast is for people who are live streamers, or who wants to host live streams for others. It’s a “one to many” broadcast much like Twitch, Facebook Live, YouTube Live, etc. Owncast is not for video conferencing or any use case where multiple people are wanting to see video of each other.

PeerTube, developed by Framasoft, is the free and decentralized alternative to video platforms, providing you over 400,000 videos published by 60,000 users and viewed over 15 million times. Our aim is not to replace them, but rather to simultaneously offer something else, with different values. PeerTube is not meant to become a huge platform that would centralize videos from all around the world. Rather, it is a network of inter-connected small videos hosters. Anyone with a modicum of technical skills can host a PeerTube server, aka an instance. Each instance hosts its users and their videos. In this way, every instance is created, moderated and maintained independently by various administrators. You can still watch from your account videos hosted by other instances though if the administrator of your instance had previously connected it with other instances. And there's more! PeerTube uses ActivityPub, a federating protocol that allows you to interact with other software.

JKVideo is a feature-rich, open-source video streaming client built with React Native, designed as a third-party interface for consuming video content similar to platforms like Bilibili. It supports multiple platforms, including Android, iOS, and web environments, providing a consistent and modern user experience across devices. The application focuses on delivering high-quality playback using technologies such as DASH streaming, ensuring smooth and adaptive video performance. It includes advanced features like live streaming support and real-time comment overlays, commonly known as danmaku, which enhance interactivity and engagement. The interface is designed with aesthetics and usability in mind, offering a visually appealing and intuitive browsing experience. JKVideo also incorporates authentication mechanisms and API integrations to interact with external content services securely.

Live API Web Console is a React starter that demonstrates how to use Gemini’s Live API over WebSockets to build real-time, multimodal experiences. The app includes modules for streaming audio playback, recording user media from the microphone, webcam, or even screen capture, and it surfaces a unified event log so you can debug the session as it flows. Configuration lives in a simple .env file and the project boots with standard web tooling, letting you experiment quickly with models, system prompts, and tool declarations. It ships with demo branches that show grounded search, function calling, and visualization—one example has the model calling a function that renders Vega/Altair graphs directly in the UI. Under the hood there’s an event-emitting WebSocket client, an audio in/out processing layer, and a minimal scaffolded view so you can focus on your app logic rather than wiring.

Start a session and invite your friends by sharing your friend code with them. Browse for your favorite media and add the URL to the queue. A number of popular websites are already supported for playback. New features are added on top of streaming websites such as real-time chat and timestamp markers. Synchronized playback of streaming media across various websites. Public, private, and offline sessions. Support for WebRTC peer-to-peer connections. Easily add watch party support to your website by redirecting the user to Metastream. Metastream used to be an Electron desktop application until development was stopped due to roadblocks in acquiring a Widevine license. The latest version can be found on the GitHub releases page.
