At Cloudflare we used IronRDP to build our Cloudflare Access RDP product [0] and scale RDP access across our edge using workers.
I can't say enough good things about the IronRDP project. I didn't write the RDP code deployed in Cloudflare Access, but I did some of the prototyping with IronRDP.
* IronRDP code was excellent, thoughtful and well designed.
* The IronRDP project was friendly, responsive and helpful. They answered some pretty obscure RDP questions I had.
I would recommend anyone doing RDP protocol work to use the IronRDP project.
*edit:* I didn't even realize it until someone pointed it out but our blog post on Cloudflare using IronRDP went live today.
