The Quest for the Ultimate Free & Open-Source Remote Desktop: Introducing RustDesk

The limitations and costs associated with traditional remote desktop solutions, such as Windows RDP's Pro edition requirement and network restrictions, prompted a search for a more versatile alternative. RustDesk emerged as an ideal, free, open-source, and self-hostable remote desktop solution, offering seamless cross-platform access and enhanced privacy.

Key Points Summary

• Introduction to Remote Desktop Needs

  Remote desktop is a crucial tool for remotely accessing computers, but the costs and limitations of existing paid RDP or remote access solutions motivated the search for a new, free, open-source, and self-hostable alternative with cross-platform compatibility.

• Limitations of Windows Native RDP

  Windows' native Remote Desktop Connection (RDC) is efficient for connecting to Windows Pro editions on the same local network. However, the target machine must run Windows Pro, which incurs an additional cost of approximately $200, and it lacks the ability to connect across different networks, rendering it unsuitable for geographically dispersed teams or mixed OS environments.

• Challenges with Mac and Linux Remote Access

  Integrating Mac into a remote desktop environment is problematic because Windows cannot natively remote into macOS, although Mac can use the Microsoft Remote Desktop app to connect to Windows Pro. Linux supports XRDP for RDP client connections, and VNC is a popular protocol, but VNC is often difficult to install, especially on Linux, and frequently lacks essential features like reliable copy/paste and GPU performance.

• Browser-Based Remote Desktop Solutions

  Browser-based options such as Guacamole and Kasm VNC offer free, open-source remote access directly from a web browser across all operating systems. While excellent for basic tasks and terminal access, these solutions typically fall short on the native client performance required for demanding operations like video editing.

• TeamViewer as a Remote Access Option

  TeamViewer offers an easy, cross-platform remote access solution that does not require a VPN, making it useful for personal remote support. Despite its features and personal free use, relying on TeamViewer's servers raises privacy concerns, and persistent prompts for paid licenses detract from its appeal for business or self-hosting purposes.

• Introduction of RustDesk and AnyDesk

  The quest for a free, open-source, self-hostable, and high-performance solution led to the discovery of AnyDesk and RustDesk. RustDesk, developed using the Rust programming language, distinguishes itself by offering free self-hosting capabilities, a truly open-source codebase, GPU acceleration, and clients for all major platforms (Windows, Mac, Linux, and mobile), in contrast to AnyDesk, which charges for self-hosting options.

• RustDesk Local Network Access (IP to IP)

  RustDesk supports direct IP-to-IP connections within the same local network when the client is installed on both machines, eliminating the need for an external server. This setup provides a direct, unencrypted connection, ideal for internal network use, and can be configured through security settings to enable direct IP access and establish a permanent password.

• TwinGate for Secure Remote Access

  TwinGate, a zero-trust network access solution, facilitates secure extension of local network access from any location, including mobile devices, or when connecting across disparate networks. It integrates seamlessly with RustDesk or native RDP clients, providing free access for home labs and small businesses (up to five users) by requiring only a connector installed on the local network.

• Setting Up a RustDesk Cloud Server

  Hosting a RustDesk server in the cloud (e.g., on Linode for $5/month) creates a publicly reachable relay server, serving as a backup for local access and enabling connections to remote clients not on the same VPN or network. This server discovers clients via their ID and can either establish direct connections or relay them if network firewalls prevent direct access.

• Docker Installation of RustDesk Server

  The RustDesk server, consisting of signaling (hbbs) and relay (hbbr) components, is easily deployed using Docker Compose on a cloud-based virtual machine (e.g., Ubuntu). The installation process involves installing Docker, creating a `docker-compose.yml` file with the provided configuration, and executing `docker compose up -d` to launch the services.

• Configuring RustDesk Clients with a Custom Server

  RustDesk clients utilize public RustDesk servers by default, which can be a privacy concern. To use a self-hosted server, clients must be configured by entering the server's IP address for both the ID and relay servers, along with the public key extracted from the `id_ed25519.pub` file on the server.

• RustDesk Connection Types and Performance

  RustDesk offers various connection types: local IP-to-IP (direct, unencrypted), ID-based via a custom server (potentially direct and encrypted, or relayed and encrypted if direct connection is blocked), and purely relayed (slower but universally functional). It delivers near-native client performance, including GPU acceleration, with clients available for all major operating systems and mobile devices, alongside experimental support for headless Linux.
