Steam Deck Users Get Free PS5 Remote Play via New App

For many gamers, the dream of playing high-fidelity PlayStation 5 titles on the go has long been a major selling point for Sony’s dedicated handheld, the PlayStation Portal. However, the release of a new third-party application for Valve’s Steam Deck has effectively brought that same functionality to the popular Linux-based handheld, potentially saving users hundreds of pounds.

The application, known as 'Chiaki4deck', is a specialized fork of the open-source Chiaki project. It is designed to bridge the gap between Sony’s proprietary Remote Play ecosystem and the versatile SteamOS interface. By configuring the app, Steam Deck users can stream their PS5 library directly from their home console, mirroring the experience offered by Sony’s £200 hardware without the need for additional investment.

While Sony’s PlayStation Portal was launched to provide a dedicated, low-latency streaming experience specifically for the PS5, it has faced criticism for being a single-use device. It requires a stable Wi-Fi connection and cannot run games natively or browse the internet. In contrast, the Steam Deck is a fully functional handheld gaming PC. By utilizing Chiaki4deck, users can now transform their existing Steam Deck into a de facto PlayStation handheld, consolidating their mobile gaming needs into one piece of hardware.

Setting up the streaming capability does require a degree of technical patience. Users must first enable Remote Play on their PlayStation 5 console and then sync the device with the Steam Deck app using a specific account ID code. Once connected, the app provides a surprisingly responsive experience. Recent updates to Chiaki4deck have improved performance, adding support for 1080p streaming, which matches the resolution of the PlayStation Portal itself. Furthermore, the app supports the Steam Deck’s touchpads and back buttons, which can be mapped to simulate the PS5 controller’s touchpad, a necessary feature for navigating in-game menus.

The rise of third-party solutions like this highlights the growing ecosystem around Valve’s handheld. Because the Steam Deck operates on a Linux-based operating system, it is fundamentally an open platform. This allows enthusiasts and developers to create tools that integrate features that major console manufacturers often gate behind proprietary hardware. While Sony has not officially endorsed these third-party streaming clients, the community-driven development has provided a robust alternative for those who already own a Steam Deck and do not wish to purchase a secondary, single-purpose device.

There are, however, limitations to consider. Unlike the PlayStation Portal, which is optimized exclusively for the PS5’s low-latency streaming protocol, the Steam Deck’s performance with Chiaki4deck is heavily reliant on the user’s home network stability. A high-speed 5GHz or 6GHz Wi-Fi connection is recommended to avoid visual artifacts or input lag. Additionally, because this is an unofficial project, it does not receive the direct software support that a first-party Sony product enjoys, meaning users may need to troubleshoot network configurations or updates on their own.

Despite these caveats, the ability to play titles like God of War Ragnarök or Spider-Man 2 on a Steam Deck screen is a significant development for the community. For current owners of both systems, it represents a 'best of both worlds' scenario: the expansive library of Steam games combined with the premium offerings of the PlayStation ecosystem, all playable from the comfort of a sofa or during travel. As the Steam Deck continues to mature as a platform, these types of innovative software solutions underscore the value of hardware freedom in the modern gaming landscape.
