HOW IT WORKS
How to view CS2 demo replays on Windows
Install the viewer
Choose a published Windows release, read its requirements and install it. Prepare Steam and your installed CS2 copy.
Downloads ↗Activate your license
Paste the license code from your purchase email into the app. No account is needed. One device and an internet connection are required.
Get a license ↗Open a local demo
Open a local .dem, .dem.gz or .dem.zst recording from the application. Keep the original file available: the demo library stores shortcuts to it. Navigate rounds, follow perspectives and save notes for your next review.
Documentation ↗Review one round at a time
Start with a round you want to understand. Follow a recorded player, pause before the key event and replay at a slower speed. Add a bookmark and note so you can return to that moment.
If a demo parses but playback fails, check the installed CS2 build and the release's known issues. Recorded voice depends on the recording; timing is an engine/capture estimate, not sample-exact synchronization.
