The Only Sleeper Trade Analyzer That Tracks Results

Other tools grade trades at the moment they happen. We go further, tracking dynasty value changes and actual fantasy points produced since the deal. See who really won.

Trade Analyzer

Every trade in your league is graded using three pillars: player value at the time of trade, how values have changed since, and the actual fantasy points each side has produced. See who won each deal, by how much, and track trade partner tendencies across seasons. Redraft, keeper, and dynasty leagues all get the same receipts, and the realized-points pillar answers the question redraft managers actually ask: what did each side score after the deal. No other Sleeper tool does this.

How It Works

My Fantasy Analyzer connects to the Sleeper API to pull your league data in real time. We automatically discover every season your league has played and combine the stats into one dashboard. Player trade values are powered by My Fantasy Analyzer's own value model, updated regularly, with alternative value sources available in settings. Your data is never stored on our servers. Everything runs in your browser.

Supported League Types

Works with any Sleeper fantasy football league: redraft, keeper, or dynasty. Redraft leagues get the same trade analyzer, draft grades, and playoff odds as dynasty leagues, with no dynasty setup to work through first. Supports SuperFlex and 2QB formats, custom roster slots, and leagues of any size.

Frequently asked questions

Is My Fantasy Analyzer free?

Yes. The league analytics are free and need no account: trade grading, draft grades, mock drafts, the live draft assistant, playoff odds, standings, and roster values all run without signing in. An optional Premium subscription adds the AI surfaces, such as the League Assistant chat and the AI insight panels.

Does it work with dynasty leagues?

Yes, and with redraft and keeper leagues too. Roster slots, league size, and scoring come straight from your league, so SuperFlex, 2QB, tight end premium, and custom stat bonuses are all handled. Dynasty leagues additionally get roster values, pick values, and multi-season history.

How do I analyze my Sleeper league?

Enter your Sleeper username on the home page and pick the leagues you want. There is no login, no password, and nothing to install. Your leagues are read from the public Sleeper API and analyzed in your browser, and every season your league has played is found automatically.

How are trades graded?

Every trade gets three grades, not one: what the players were worth on the day the trade was accepted, how those values have moved since, and the fantasy points each side has actually produced from the players involved. The third pillar is the receipt, so a deal that looked fair on paper and then went one way says so. Read the full grading methodology →

Is my league data stored?

There is no copy of your league sitting on our servers. League rosters, transactions, and matchups are read from the public Sleeper API each time you load a league and analyzed in your browser, with AI features sending the relevant context to our edge functions to answer. An optional account stores only your email, your saved Sleeper username and league IDs, and your preferences.

Which fantasy football platforms are supported?

Sleeper. Every feature reads your league through the public Sleeper API, so any Sleeper football league works, including Chopped survivor formats. ESPN, Yahoo, and MyFantasyLeague leagues are not supported.
