Dynastr

Dynastr is a fantasy football league platform built for commissioners and long-running leagues. It helps users manage league operations in one place, replacing spreadsheets, chat apps, and manual workflows while allowing each league to retain its preferred rules. Commissioners can import league history, rosters, settings, and provider data from ESPN, Sleeper, Yahoo Fantasy, NFL Fantasy, or MFL, without rebuilding everything from scratch.

The platform supports dynasty, keeper, salary-cap, auction, redraft, IDP, and best-ball formats. Its tools include contracts and salary-cap management, draft and waiver features, custom scoring, schedule editing, roster enforcement, anti-tanking rules, audit logs, and other commissioner controls. Users can explore a populated demo league with teams, draft history, standings, scoring, and management tools.

Standard league features are free, including imports and mobile access. Dynastr also offers an optional AI Toolkit for $80 per year per user, with trade analysis, waiver suggestions, draft recommendations, start/sit advice, and league recaps. Dynastr is operated by KEH Interactive LLC.
