Leetify or a 3D demo viewer: which one do you need?
They answer different questions. Leetify describes itself as a way to "compare your performance to your friends" with match reports and ratings. That needs many matches. A 3D demo viewer rebuilds one match in the real map to show why a round went wrong.
Memorin is the second kind, and it opens a Leetify match link as a 2D replay, with 3D for PRO. It has no rating across matches; for that, use Leetify.
What is the difference between a stats platform and a 3D demo viewer?
A stats platform turns many demos into numbers: trends, per-map results, ratings. Those need many matches to mean anything, because one game is mostly noise. It answers "am I getting better, and at what?".
A 3D demo viewer takes one match and rebuilds it in the real map geometry. You put the camera where a player stood and see the angle they held. It answers "why did that round fall apart?".
| Your question | Use |
|---|---|
| Am I improving over three months? | Stats platform |
| How do I compare with my friends? | Stats platform |
| Which map drags my numbers down? | Stats platform |
| Why do I keep dying at this spot? | 3D demo viewer |
| Did that smoke block the angle? | 3D demo viewer |
| Is my opening-duel rate a real problem? | Stats first, then a viewer for the duels |
The numbers tell you where to look. The replay shows what you were doing there.
How do I open a Leetify match in 3D?
Paste the Leetify match link into Memorin's import box, after a free Steam sign-in. The match is resolved, fetched and rebuilt as a 2D replay, with 3D for PRO.
| You have | Do this |
|---|---|
| A Leetify match link | Paste it |
| A FACEIT match | Use the Watch in 3D extension, or drop the file |
A match sharing code (CSGO-…) | Paste it |
A direct link to a .dem file | Paste it |
| A downloaded demo | Drop it in: .dem, .dem.gz, .dem.zst or .dem.bz2 |
Temporary signed download links are refused, because they expire. Paste the Leetify match link or a share code instead, or upload the file.
Watch a real round, take over and play it. Today's moment is free in 3D, with no account.

What does Leetify say it does?
In its own words, checked on its site on 28 September 2026: "Compare your performance to your friends with detailed match reports, aim and utility ratings, highlights, and more." That is the stats-platform job, done across your match history.
This page makes no other claim about Leetify's features or prices. Anything more would come from memory, not from its site.
What does a 3D replay show that a stat cannot?
Geometry. A stat records that you died holding an angle. Standing in that spot in the rebuilt map shows whether the angle was open to a second door, whether a box put your head at pre-aim height, and what the attacker could see of you.
Memorin rebuilds ten maps this way: Ancient, Anubis, Cache, Dust II, Inferno, Mirage, Nuke, Overpass, Train and Vertigo. You can also walk a map on its own, free and with no account.
What can neither a stats page nor a replay do?
Train the response. Watching a death teaches you to spot it. A Replay Moment (PRO) puts you back in that situation at the decision point, with the same positions and utility, and lets you play it until the answer is automatic. Replaying vs rewatching explains why that matters.
Where does Memorin lose to a stats platform?
- No rating across matches. Memorin's stats are per demo. Leetify and csstats.gg track you over time.
- No friend comparison. There is no leaderboard of you against your friends over a season.
- Whole-tick playback. Sub-tick command order inside a tick is not recovered. The in-game player is the reference for that.
Most people who use both use them for different questions. The CS2 demo viewer comparison covers the other viewers, each claim from its own site.
FAQ
Is Memorin a Leetify alternative?
Not a replacement. Leetify compares your performance across matches with reports and ratings. Memorin rebuilds one match in 2D, or in 3D with PRO, to show why a round went wrong. Many people use both.
How do I compare Leetify stats with what happened in the round?
Use the stats to find the rounds, then open that match in a 3D viewer. Paste the Leetify match link into Memorin and jump to those rounds.
Can I open a Leetify match link in Memorin?
Yes. A Leetify match link is one of the accepted imports, with match sharing codes and direct demo links. Paste it and the match is rebuilt as a replay: free in 2D, and in 3D with PRO.
What can a 3D demo viewer show that a stats platform cannot?
Geometry. Standing in the rebuilt map shows whether an angle was open to a second door, whether a box changed your head height, and what the attacker could see of you.
Does Memorin have a player rating across matches?
No. Its stats are per demo. For a rating or a trend over many matches, a stats platform such as Leetify or csstats.gg is the right tool.
Do I need an account to watch a demo?
Not for pro matches in 2D, shared moment links or the daily moment. Adding your own demo needs a free Steam sign-in, and 3D is PRO.
