#2 Xpra vs X2Go – Key Differences

2.1 Core Functionality

Xpra allows you to stream individual Linux GUI applications from a remote host and display them as native windows on your local desktop — offering app-level isolation, seamless integration, and minimal resource overhead.

X2Go delivers a complete remote desktop session, enabling users to interact with a full Linux graphical environment as if they were physically logged in — ideal for multi-application workflows and desktop continuity.

✔ Xpra excels in lightweight, per-application access, while X2Go is purpose-built for full-session desktop experiences with multi-user scalability.

2.2 Session Type & Persistence

Xpra provides persistent, per-application sessions — each remote app runs independently and can be reconnected to without affecting other applications. Even after a disconnection, individual apps remain live on the server, resuming exactly where you left off.

X2Go offers full desktop session persistence, preserving the entire graphical environment — windows, apps, session state — allowing users to reconnect later and resume the complete desktop as-is.

✔ Xpra is ideal for modular, app-focused workflows, while X2Go is better suited for users who need full desktop continuity across sessions.

2.3 Platform Integration

Xpra integrates remote Linux applications directly into the host desktop (Windows, macOS, or Linux), making each app appear and behave like a local window — ideal for users who need seamless cross-platform app usage without launching a full desktop session.

X2Go provides a full remote Linux desktop experience accessible from Windows, macOS, or Linux clients, delivering a consistent graphical environment regardless of the user's local operating system.

✔Xpra offers native-like app embedding for smoother cross-platform workflows, while X2Go focuses on delivering a complete remote desktop regardless of the local system.

2.4 Protocol & Transport

Xpra utilizes its own custom protocol, capable of operating over TCP, SSL, SSH, and even WebSocket for browser-based access. This flexibility allows it to adapt to different network setups and security requirements, including modern web-based workflows.

X2Go relies entirely on the NX protocol tunneled over SSH, ensuring encrypted communication with efficient compression, but with less flexibility in transport modes.

✔Xpra offers greater transport versatility across modern and legacy environments, while X2Go keeps it simple and secure with a streamlined SSH-based pipeline.

2.5 Mobile & OS Support

Xpra provides limited Android client support and an HTML5 browser-based client, enabling users to access remote applications even without installing a native client — useful for lightweight, mobile, or browser-based workflows.

X2Go does not offer official mobile apps or web client support; remote access is available only through its native desktop clients (Windows, macOS, Linux).

✔Xpra extends access to web and mobile platforms, while X2Go remains focused on traditional desktop-to-desktop connectivity.

2.6 Security Architecture

Xpra supports multiple layers of security, including SSH tunneling, SSL/TLS encryption, and customizable access control policies. It also allows fine-grained configuration of authentication hooks, encryption levels, and user session permissions — offering flexibility for both desktop and browser-based deployments.

X2Go enforces SSH-only transport, meaning all remote desktop sessions, file transfers, and audio streams are encapsulated within a secure SSH connection. It uses the system's native SSH configuration and authentication methods (e.g., public key, password, or PAM).

✔ Xpra provides broader security configuration options for complex or web-based environments, while X2Go offers strong, out-of-the-box SSH security ideal for straightforward deployments.

2.7 Low Bandwidth Performance

Xpra excels in constrained networks by using adaptive, bandwidth-efficient codecs such as WebP, JPEG, H.264, and AV1. It intelligently transmits only updated regions (damage-based rendering), which significantly reduces data usage — ideal for remote app usage over slow or unstable connections.

X2Go performs well in low-bandwidth scenarios by leveraging the NX protocol, which compresses full desktop streams efficiently. It's especially effective when paired with lightweight desktop environments like XFCE or MATE, though full-session rendering naturally consumes more bandwidth than per-app streaming.

✔Xpra is better optimized for minimal, granular data transfer, while X2Go delivers solid performance for full desktop sessions — especially when paired with lightweight GUIs.

2.8 Multi-User Environment

Xpra supports concurrent multi-user access, where each user runs independent application sessions under their own Linux system account. Sessions are fully isolated per user, and multiple users can connect to the same server simultaneously to run different remote apps without conflict.

X2Go is designed for true multi-user environments, enabling each user to initiate their own full desktop session, completely separated from others. It supports centralized user management (e.g., LDAP, PAM) and handles session isolation, authentication, and access controls reliably.

✔Both tools offer multi-user capabilities, but Xpra excels in app-level isolation, while X2Go is better suited for environments requiring full desktop isolation and user session management.

2.9 Multi-Monitor Support

Xpra natively supports multi-monitor setups by allowing each remote application window to behave like a local app — meaning you can freely move and arrange them across multiple local displays without restrictions.

X2Go streams a single remote desktop session within a window or fullscreen on the client. While you can manually stretch or span that session across monitors, it does not provide native multi-monitor awareness or control like true per-display rendering.

✔Xpra offers superior flexibility for multi-display workflows by treating each app window independently, while X2Go limits users to a mirrored single-session experience on multiple monitors.

#3 Xpra vs X2Go – Advance Differences

3.1 Graphics Acceleration & GPU Support

Xpra supports OpenGL forwarding and integrates with VirtualGL to enable remote 3D rendering, making it suitable for applications that require GPU acceleration (e.g., CAD, visualization tools). It also supports hardware-accelerated video decoding on the client side for efficient playback of streamed content (e.g., H.264, AV1).

X2Go relies entirely on software rendering and lacks support for GPU-accelerated OpenGL or 3D graphics. Applications requiring hardware graphics support may fail to render correctly or perform poorly in this environment.

✔Xpra is better suited for graphically intensive or GPU-aware applications, while X2Go is optimized for 2D desktop environments without 3D or OpenGL dependencies.

3.2 Collaboration & Shadowing

Xpra includes collaborative features such as session shadowing, where multiple users can view the same application session in real time. It also supports broadcasting an app to multiple clients and allows view-only or interactive access, making it useful for support, training, or collaborative tasks.

X2Go does not support shared sessions, shadowing, or multi-user collaboration within the same session. Each user's session is fully isolated and cannot be accessed or viewed by another user unless separately configured at the system level.

✔Xpra enables real-time collaboration and support scenarios through shared session access, while X2Go prioritizes user isolation and does not support session sharing or shadowing natively.

3.3 Installation & Dependency Footprint

Xpra has a heavier dependency footprint due to its support for advanced features like multimedia forwarding, encoding/decoding (e.g., H.264, WebP, AV1), WebSocket/HTML5 access, and VirtualGL. Setup can involve manual configuration, codec installation, and custom session scripting depending on the environment.

X2Go is easy to install using standard system packages like x2goserver and x2goclient, available in most major Linux repositories. It has minimal dependencies and is considered user-friendly, especially for sysadmins and beginners setting up remote desktop access.

✔Xpra is more feature-rich but requires careful setup and dependency handling, while X2Go is quick to deploy and well-suited for fast rollouts or standardized environments.

3.4 Video, Audio, Webcam

Xpra supports audio forwarding, streaming sound from the remote application to the local client. It also includes experimental support for webcam and video device forwarding, allowing certain camera-based applications to function remotely, though stability and compatibility may vary depending on platform and configuration.

X2Go offers reliable audio forwarding via PulseAudio, delivering desktop and application sound to the client. However, it does not support webcam or video device redirection, making it unsuitable for applications requiring camera input or video conferencing tools.

✔Xpra provides broader multimedia forwarding capabilities — including basic webcam redirection — while X2Go focuses on stable audio support and does not handle video devices.

3.5 Printing & USB Forwarding

Xpra does not support USB device or printer redirection natively. Any access to remote printers must be configured manually via network printing protocols like IPP/CUPS. USB forwarding is not available, aligning with Xpra’s focus on application streaming over hardware passthrough.

X2Go supports printer redirection through the cups-x2go package, enabling remote applications to print directly to the client’s local printer. However, USB device forwarding (e.g., flash drives, webcams, scanners) is not supported.

✔X2Go includes built-in printer forwarding, making it better suited for basic office productivity use, while Xpra lacks native device redirection and relies on manual or network-based configurations.

3.6 Wayland & X11 Compatibility

Xpra is built primarily for X11 environments and works seamlessly with traditional X server applications. It offers experimental Wayland support, typically by running apps inside an Xwayland wrapper — useful but not yet fully stable for native Wayland workflows.

X2Go is strictly tied to Xorg (X11) and is not compatible with Wayland. Systems running native Wayland sessions (like GNOME on Fedora) must switch to an Xorg session for X2Go to function properly.

✔ Xpra provides limited flexibility for Wayland setups via Xwayland, while X2Go is locked to classic X11 and will not operate under native Wayland sessions.

3.7 Resource Usage (CPU/RAM)

Xpra is designed for minimal resource consumption, as it streams individual applications rather than entire desktops. This makes it highly efficient in terms of CPU and RAM usage, especially on low-spec servers or virtual machines running lightweight apps (e.g., terminals, editors).

X2Go launches full desktop environments, which naturally require more CPU and memory — especially with heavier desktop environments like KDE or GNOME. Even with lightweight desktops like XFCE or MATE, each session includes background services, panels, and window managers.

✔Xpra is ideal for low-resource deployments and app-focused workloads, while X2Go trades higher resource usage for a complete remote desktop experience.
