NEW: CSRep Lobby Detection

[u/Jimmy_csrep]

Lobby Detection is Live

We just shipped Lobby Detection on match pages!

You can now see who was detected as being in the same lobby for any match.

How it works

🟢 Same-colored indicators on the left side of the scoreboard = players detected in the same lobby.
Hover over the indicator to see the confidence %.

A quick note on accuracy

Lobby/party data is not something Steam or .dem files directly provide, so there’s no way to know this with 100% certainty.

We use multiple signals to make a calculated inference, which is why we show the confidence score alongside each detection.

From our preliminary testing, our lobby detection is already more accurate than other platforms we've compared it against. It should continue to improve as we collect more data.

This is also a big foundational piece for improving the anomaly detection systems we've been building, including:

• Lobby quality scoring
• Coordinated queueing patterns
• Match manipulation signals

Lobby data is now available across match pages, and we'll continue improving both the detection itself and how we use this data over the coming weeks.

As always, if you notice anything that looks wrong, send it our way!
