Introducing My Fantasy Analyzer: Free Advanced Analytics for Sleeper Leagues
announcement · feature
Fantasy football is more fun when you have the data to back up your trash talk. My Fantasy Analyzer is a free analytics tool for every Sleeper fantasy football league. No login required.
Why We Built This
Sleeper is one of the best fantasy football platforms out there, but its built-in analytics only scratch the surface. Who really won that blockbuster trade from last year? Was your first-round rookie pick actually smart, or did you reach? Are you winning because you're good, or because your schedule has been soft?
We built a free tool that covers trades, drafts, standings, matchups, and performance, all from a single Sleeper username. No sign-in, no subscription.
What You Get
Trade Grading with Realized Results
Every trade in your league's history gets graded across three pillars: the dynasty value exchanged on trade day, how those values have shifted since, and the actual fantasy points each side produced. Not just who won on paper, but who won on the field.
Draft Board & Pick Grading
See every pick from your completed rookie and startup drafts with letter grades. Each pick gets a Draft Day grade (was it the right call at the time?) and a Revisionist grade (how has it aged?). The grading uses real draft pool data, comparing your pick against the best player actually available rather than a synthetic model.
Advanced Standings & Awards
Power rankings, luck scores, lineup efficiency, and consistency metrics beyond basic win-loss records. The awards section crowns 12 different champions, from Best Record to Luckiest Manager to Win Streak King.
Head-to-Head Rivalries & Matchup History
Drill into your record against every opponent. See splits between regular season and playoff performance. Find out who dominates your league's biggest rivalries and who chokes when it matters.
Multi-Season Dynasty History
We trace your league's history across every connected season and combine records, stats, and trends into a single view. Five years of dominance or five years of rebuilding, all in one place.
How It Works
- Enter your Sleeper username (no login or API key needed)
- Select your leagues (pick one or combine multiple seasons)
- Explore your data across seven tabs of analytics covering every angle of your league
Everything runs in your browser using Sleeper's public API and DynastyProcess dynasty values. Your data stays on your device. We don't store any league information on our servers.
What's Coming Next
We're actively building new features based on community feedback. Dynasty roster valuations, trade calculators, and deeper playoff analysis are all on the roadmap. Follow along with our blog for updates on every new feature and methodology improvement.
