I tried dozens of TeamViewer alternatives and I keep coming back to this free open-source tool
The TeamViewer alternative I wish I had found sooner

Like many, I relied on TeamViewer’s free plan for quick remote assistance, but the constant session timeouts and frustrating limitations quickly became unbearable. I needed something reliable, something that wouldn’t cut me off mid-task. Here is where I started exploring the world of remote desktop alternatives to find a solution that prioritizes functionality over limitations (and subscriptions). After trying dozens, I came across RustDesk, and it quickly ticked all the boxes for me.
