Question 1

How do I view CS2 demo files online?

Go to the Demo Viewer page, drag and drop your .dem file, and the tool parses it locally in your browser using WebAssembly. You can then select any round and watch a 2D replay with all player positions, kills, and grenades. No download or account needed.

Question 2

Is this CS2 demo viewer free?

Accepted Answer

Yes, Recoil Analytics is completely free with no account required. Your demo files are parsed locally in your browser by default and are never uploaded unless you choose to. Pro subscribers can optionally upload demos for server-side AI insights.

Question 3

What demo formats are supported?

Is my demo data private?
