Run Log Analyzer

Load your local Slay the Spire 2 run history and see win rates by character, ascension, card pick, relic, and encounter. Files are parsed in your browser — nothing is uploaded.

Pick your run history folder

Slay the Spire 2 writes a JSON file to your save folder after every run. Drop in your history folder (or the individual .run files) and we'll compute win rates entirely in your browser.
