Guppy is the draft-prep tool serious managers swear by. Mock the first round fifty times and draft straight off Guppy's rankings, tiers, and cheat sheet — tuned to your league — so you walk in already knowing every pick.
Everyone shows up with the same rankings. The managers who win are the ones who already ran the board, knew their tiers cold, and had a plan for every turn. Guppy is how you get there.
Draft solo against bots that pick like real managers, or pull friends into a practice room before it counts. By draft day, every turn is muscle memory.
Guppy ranks and tiers all 274 players for your exact league format — so you can see the gaps before a run starts and draft straight off the cheat sheet. No spreadsheet required.
See exactly where every player is going across thousands of real drafts. Guppy flags the value sitting in front of you — and the reaches to avoid.
Draft the players whose road eases up when the fantasy playoffs hit — and fade the brutal closing slates.
A live shortlist of late-round picks with league-winning upside, ranked by opportunity not name value.
Live, sortable, and synced — cross players off as they go and keep your plan in front of you the whole draft.
Paste your ESPN link to pull your exact scoring and roster settings — or just start a mock, no league required.
Guppy loads a ranked, tiered player pool tuned to your format. Scan the tiers, set your targets, and you've got a cheat sheet to draft from.
