NymphCast review 2026: what this open-source Raspberry Pi casting server can do, how it compares to Chromecast, and where to find setup docs and alternatives.
Researched and fact-checked by Bartu Cavusoglu · Updated July 19, 2026
NymphCast is an open-source project that turns Linux-capable hardware, most often a Raspberry Pi, into a network audio and video receiver for a television or powered speakers. It was created by developer Maya Posch and is documented on the Nyanko project website, with source code hosted on GitHub under a BSD license.
Unlike commercial casting devices, NymphCast is entirely self-hosted and free to use: there is no company, subscription, or account system behind it, and users install the server software themselves on supported hardware and connect using the available client applications.
The NymphCast server receives audio and video streamed from client devices on the local network, as well as internet media, and outputs it to a connected display or speakers. Client options include command-line tools, a graphical client, and an Android application, all of which can discover and control a NymphCast server.
NymphCast also supports a preview-status apps system built on AngelScript, allowing developers to extend the server with support for additional streaming protocols or build custom on-screen interfaces for the client. As an actively evolving hobbyist project, some app features and protocol integrations remain experimental.
NymphCast is completely free and open source, released under a BSD license with no paid tier, subscription, or commercial edition. Users only incur the cost of the hardware they run it on, such as a Raspberry Pi.
Yes, NymphCast is a free, open-source project released under a BSD license with no subscription or paid edition.
NymphCast was created by developer Maya Posch and is documented on the Nyanko project website, with source code hosted on GitHub.
NymphCast is designed to run on Linux-capable single-board computers, most commonly the Raspberry Pi.
Conceptually yes, NymphCast lets you cast audio and video to a connected receiver, but unlike Chromecast it is open source, self-hosted, and not tied to a commercial vendor or account.
NymphCast supports command-line clients, a graphical desktop client, and an Android app for discovering and controlling servers on the network.
The project continues to be developed on GitHub, though as a single-maintainer open-source project some features, including its apps system, remain experimental.
Documentation is hosted on the Nyanko project website alongside the source code and releases on the MayaPosch/NymphCast GitHub repository.
