Run history, stats, and co-op, in your browser.

Drop your Slay the Spire 2 save folder in to see the same Overview, Characters, Ascensions, Relics, Cards, and Recent Runs tabs the macOS app has. Everything stays in your browser — nothing uploads. Optional Steam sign-in unlocks the live co-op partner feed.

Checking who's around…

Heads up: you're in an in-app browser (app) that may break Steam sign-in. Tap the share / menu button and choose Open in Safari (iOS) or Open in Chrome (Android) first.

What signing in actually does

  • Verifies you own the Steam account you claim, via Steam OpenID.
  • Mints a 30-day session. No password ever leaves Steam.
  • Pulls only your persona name and avatar.
  • Posts your status to the public feed only while this tab is open.
  • Sign out at any time to drop your row from everyone's feed.
