About Leaguefolio

Leaguefolio is an independent project built for the practical work of managing several fantasy football teams: spotting lineup problems, comparing player exposure, following matchups, and keeping league administration organized.

Useful before you connect a league

Our public guides explain the tools with worked examples and limitations. Our dynasty transaction research shows observed trade packages with sample sizes and collection dates. Examples labeled fictional are demonstrations, not real user portfolios or predictions.

Your decisions stay yours

Core Sleeper tools can be used with a public username; an account is optional for saved features. Leaguefolio is not affiliated with or endorsed by Sleeper, the NFL, or its teams. Projections and analysis are estimates. Review current information and your league rules before acting, and confirm any roster changes in your league.
