I put together an open-source archive of Counter-Strike's historical Monthly Players data, covering CS:GO → CS2 from 2013 to present.

The data is based on the Monthly Players figure published on Counter-Strike's official website (counter-strike.net). The underlying data is collected from Steam's official Web API, while historical snapshots from the Wayback Machine are used to preserve older records.

I also built a tracker to make the full history easier to explore.

A few things I found interesting while going through the dataset:

• CS2's monthly player count is higher than most of the CS:GO era.
• The all-time peak is 32,656,431 in March 2026, during the CS2 era.
• The CS:GO-era peak was 29,303,030 in April 2023.
• In 2026, monthly players increased 9.1% from May to June, then declined 5.7% in July, while still remaining above 30 million.
• Following the Shanghai Major in November 2024, monthly players rose from roughly 25–27 million to around 30 million.

The dataset makes it possible to look at the CS2 transition in the context of the broader CS:GO era, rather than only looking at current player counts.

The raw historical data is available in the repository for further analysis.
