About STS Tracker
A community stats tracker for Slay the Spire 2.
What is this?
STS Tracker aggregates run data from Slay the Spire 2 players to provide global meta-analysis — character win rates, card correlations, encounter difficulty, deck archetypes, and more. Think of it as a community-powered stats dashboard.
You can also track your own personal stats by signing in with Steam and uploading your run files.
How do I upload runs?
There are three ways to get your run data into the tracker:
Manual upload
Sign in with Steam, go to Upload, and drag your .run files. They're located in your Slay the Spire 2 save directory: C:\Users\<YourUsername>\AppData\Roaming\SlayTheSpire2\steam\<SteamID>\profile1\saves\history
In-game mod (recommended)
Install the Card Rewards Helper mod to get real-time card pick recommendations on reward screens, event choices, and shops. Also auto-uploads completed runs and syncs your active run to the browser companion.
Desktop auto-sync
Download rusty-sts, a lightweight desktop app that lives in your system tray and automatically uploads new runs as you play. Set it up once and forget about it.
Use either the mod or rusty-sts for automatic uploads, not both — they'll create duplicates.

Privacy
Only game run data is stored — no personal information beyond your Steam display name and avatar. Your data is used to compute aggregate stats visible on the global dashboard. Individual run details are only visible to you.
Korean Translation
I noticed a big chunk of our players are from South Korea — so I added Korean language support!
The translation is still a work in progress, especially for in-game content like card names and descriptions. If you spot any awkward translations or have suggestions, feel free to reach out. Thank you to all the Korean players for using the tracker!
Support the Project
STS Tracker is a passion project I build and maintain in my free time. If you find it useful and want to help keep it running, you can buy me a coffee. It helps cover server costs and lets me spend more time adding new features. Thank you for your support!
