Read your league
You provide access to an ESPN league you are authorized to use. ESPN credentials stay on your computer; they are not sent to Kyle or a hosted Almanac service.
Fantasy League Almanac
Turn years of fantasy-baseball history into a league record book.
Fantasy League Almanac is a desktop application that extracts the history of a league you can access, processes it locally, and builds a browsable almanac. Its optional Google workflow creates a workbook in your own Drive.
A live demo dashboard, a web layer over the same data.
How it works
Your league goes in. A historical record book comes out.
The supported public workflow currently focuses on ESPN fantasy-baseball leagues. It reconstructs seasons, teams, owners, players, matchups, standings, drafts, transactions, records, and derived historical comparisons from the data ESPN provides.
Build locally
The application extracts data to local Parquet files, loads DuckDB, and runs the project models on your machine. No Snowflake or hosted warehouse account is required.
Create the almanac
The result is a record book with league history and comparisons. If you choose the Google workflow, the application creates a new workbook in the Google account you select.
Data boundaries
Designed to run under the user’s control.
The supported v1.9 public Google-workbook workflow runs on Windows and stores its Google authorization in Windows Credential Locker. The broader project remains open for inspection on GitHub.
Local credentials and data
ESPN cookies, extracted league data, and the local DuckDB database remain on the user’s computer by default.
No maintainer backend
There is no hosted Almanac account database, analytics service, advertising, payment collection, telemetry, or automatic upload of logs or workbook links.
User-controlled sharing
The app names the real league content that may appear before asking whether to enable anyone-with-the-link viewer access.
