IronRDP: Rust-Based RDP Implementation Gains Traction, Powers Cloudflare's Browser-Based Solution

In the world of remote desktop protocols, Microsoft's Remote Desktop Protocol (RDP) has long been considered the gold standard for performance and usability. Now, a new Rust-based implementation called IronRDP is gaining attention for its focus on security and cross-platform capabilities, with major organizations like Cloudflare already leveraging it for enterprise solutions.

Security-Focused RDP Implementation in Rust

IronRDP offers a collection of Rust crates that implement Microsoft's Remote Desktop Protocol with a strong emphasis on security. This focus is particularly relevant given RDP's history of memory-related vulnerabilities. By using Rust's memory safety guarantees, IronRDP aims to eliminate entire classes of security issues that have plagued traditional C/C++ implementations. The project supports various video codecs including raw bitmap, Interleaved Run-Length Encoding, RDP 6.0 Bitmap Compression, and Microsoft RemoteFX (RFX), providing flexibility for different network conditions and performance requirements.

Supported Video Codecs in IronRDP:

  • Uncompressed raw bitmap
  • Interleaved Run-Length Encoding (RLE) Bitmap Codec
  • RDP 6.0 Bitmap Compression
  • Microsoft RemoteFX (RFX)

Implementation Components:

  • Full-fledged asynchronous RDP client
  • Blocking/synchronous example implementation
  • Server-side components (early stage)
  • Web/WASM compatibility
  • .NET bindings

Real-World Deployments:

  • Cloudflare Access RDP product
  • Devolutions Gateway integration
  • Potential future integration with Proxmox as VNC/SPICE alternative

Enterprise Adoption and Real-World Applications

Cloudflare has already integrated IronRDP into their Access RDP product, which was announced in a blog post coinciding with IronRDP's appearance on tech forums. A Cloudflare employee shared their positive experience with the project:

At Cloudflare we used IronRDP to build our Cloudflare Access RDP product and scale RDP access across our edge using workers. I can't say enough good things about the IronRDP project. The code was excellent, thoughtful and well designed. The IronRDP project was friendly, responsive and helpful.

This endorsement highlights IronRDP's readiness for production use in enterprise environments, particularly for browser-based RDP solutions that require WASM compatibility.

Community Perspectives on RDP Technologies

The discussion around IronRDP has sparked broader conversations about remote desktop technologies. Many users express strong appreciation for RDP's performance characteristics, particularly its ability to function well even on limited bandwidth connections. Unlike video-streaming based solutions, RDP can maintain text crispness and UI responsiveness by having the client handle some rendering tasks locally.

However, others point out that for specific use cases like gaming or video-intensive applications, alternatives such as Sunshine+Moonlight or RustDesk might offer better performance through hardware-accelerated video encoding (H.264, HEVC, or even AV1). These solutions prioritize frame rate and visual fidelity over bandwidth efficiency.

Cross-Platform Implications

IronRDP's emergence comes at an interesting time for Linux desktop users. Several commenters noted that Linux has historically lacked high-quality remote desktop solutions comparable to Windows RDP. While GNOME and KDE have recently added RDP server support, users report that performance still doesn't match Windows implementations. IronRDP could potentially help bridge this gap, especially as projects like Proxmox consider it as a replacement for VNC or SPICE in virtualization environments.

The project's architecture allows for multiple integration paths - from standalone clients to web-based solutions compiled to WebAssembly. This flexibility makes it particularly valuable for cross-platform scenarios where consistent remote desktop experiences are needed.

As remote work continues to be a significant part of modern work environments, secure and performant remote desktop solutions remain crucial infrastructure components. IronRDP's security-focused approach and growing adoption suggest it could become an important player in this space, especially for organizations concerned about the security implications of traditional RDP implementations.
