Watch a CS2 demo without downloading anything
Yes, you can watch a CS2 demo without downloading it. Sign in to Memorin with Steam and paste a match link: a CS2 match sharing code, a Leetify match link or a direct demo URL. For FACEIT, use the Watch in 3D extension in the matchroom.
The server fetches and unpacks the recording, and your browser draws the match in 2D, or in 3D with PRO. No .dem reaches your disk and Counter-Strike 2 does not need to be installed.
.dem on your disk? That is a different question with its own guide: how to upload a CS2 demo file and watch it in your browser. This page is about never downloading the file.Can I watch a CS2 demo without downloading the file?
Yes, when the match is addressable by a link, and it takes a Steam sign-in, because an imported demo belongs to an account exactly as an uploaded one does. Sign in, paste the link, and the server fetches and unpacks the recording so nothing reaches your disk.
- Sign in. Open Memorin and sign in with Steam.
- Paste a match link. Paste a CS2 match sharing code, a Leetify match link or a direct demo URL into the import box.
- Watch. The server fetches and unpacks the recording, and the match plays in 2D in your browser, or in 3D with PRO.
| Link | Anything on your disk? | Best for |
|---|---|---|
Match sharing code (CSGO-) | No | Premier and matchmaking games |
| FACEIT matchroom, with the Watch in 3D extension | No | FACEIT matches |
| Leetify match link | No | Matches you found on Leetify |
| Direct demo URL | No | Demos hosted anywhere else |
| Uploading a file | It is already there | Old matches, private servers |
More detail: match sharing codes and FACEIT matches. If CS2 itself says "download incomplete", the share code route is also the fix: see CS2 demo download incomplete.

Can I watch a CS2 demo without installing Counter-Strike 2?
Yes. A browser demo viewer reads the recording and renders the match itself, so the game does not need to be installed on the machine you are watching from.
This works because a .dem file is not a video. It is a record of what the server knew: positions, weapons, health, utility and events. Any program that reads the format can rebuild the match. So you can review last night's game on a laptop or a work computer that has never had CS2.
What can a browser demo viewer not do?
- It is not the game engine. Playback is rebuilt at whole-tick precision, so sub-tick order is lost. For frame-exact disputes, CS2's own player is the reference.
- Ten maps only: Ancient, Anubis, Cache, Dust II, Inferno, Mirage, Nuke, Overpass, Train and Vertigo.
- It cannot show what was never recorded: your monitor or your intent.
- Parsing takes time once. A long match makes you wait at the start, not during playback.
Does a browser demo viewer work on a phone?
It runs anywhere a browser supports JavaScript and WebGL, but a full 3D map is heavy work for a small device. Expect a desktop machine to handle long matches more comfortably than a phone.
On a phone, the 2D radar view is the better fit: it loads no map and opens fast. Use a desktop for a full review or to play a moment.
