About
My Fantasy Analyzer is a comprehensive analytics tool built specifically for Sleeper fantasy football leagues. It pulls real-time data directly from the Sleeper API and presents it in a rich, multi-faceted dashboard — covering everything from trade grades to season-over-season performance trends. At its core is a powerful Trade Analyzer that evaluates every deal your league has made across three pillars: the dynasty value of each player at the time of the trade, how those values have shifted since, and the actual fantasy points each side has produced. This gives managers an objective, data-driven verdict on who won (or lost) each trade and by how much. Beyond trades, the platform delivers full league analytics including standings with 17+ sortable stat columns, dynasty roster values with position breakdowns, optimal lineup scoring and efficiency ratings, all-play win percentage, luck analysis, head-to-head matchup records, score distribution, and consistency metrics. Multi-season combined analytics let you track your league's history in one unified view. Dynasty trade values are sourced from DynastyProcess and updated regularly for accuracy. All data processing happens in the browser — nothing is stored on external servers, ensuring privacy. The tool supports redraft, keeper, and dynasty leagues of any size, including SuperFlex, 2QB, and custom roster formats. My Fantasy Analyzer is ideal for competitive fantasy managers, league commissioners, and dynasty hobbyists who want deeper insight without paying for premium tools.

Pros
- Completely Free with No Account Needed: Users can access the full suite of analytics and trade grading tools instantly without signing up, logging in, or paying anything.
- Objective, Data-Driven Trade Verdicts: The three-pillar grading system goes beyond simple value calculators by incorporating real-world fantasy point outcomes, making trade analysis far more meaningful.
- Broad League Format Support: Works with redraft, keeper, and dynasty leagues of any size, including SuperFlex, 2QB, and custom roster configurations on Sleeper.
- Privacy-Respecting Architecture: Because all processing happens in the browser and no data is stored on servers, users retain full control over their league information.
Cons
- Sleeper-Only Platform: The tool exclusively supports Sleeper leagues and cannot be used with ESPN, Yahoo, NFL.com, or other fantasy platforms.
- No Mobile App: There is no dedicated iOS or Android app — users must access the tool through a web browser, which may be less convenient on mobile devices.
- Dynasty Value Source Dependency: Trade grades rely on DynastyProcess valuations, so the accuracy of grades is tied to how frequently those third-party values are updated.
