How the OnRoto import works
Paste your OnRoto league URL and RotoHound reads the league through OnRoto’s guest pages, with no login and nothing to connect. Every roster, the league’s roster rules, and the standings import, and the FAAB acquisition log, the trade log, and the weekly bid log (every bid, including the ones that lost) sync into RotoHound’s transaction log.
Trade impact in standings points
Pick the two teams and the players on each side. RotoHound applies the trade to both rosters, rebuilds each lineup, and recalculates the projected league standings. The result is the number of standings points each side gains or loses, so a trade offer becomes a concrete number instead of a gut call.
Category-by-category breakdown
Every scoring category shows its before and after. You can see which categories the trade helps, which it costs, and how the rest of the league moves around you. Points leagues get the same treatment in projected points.
What RotoHound reads from a OnRoto league
OnRoto leagues often run an active-roster limit with swingman spots that can hold either a hitter or a pitcher. RotoHound imports the limit, treats the swing slots as either, and lets the lineup optimizer decide bat or arm for each one on projected standings points. Scoring imports as configured. The expert leagues that run on OnRoto, such as Tout Wars and LABR, import the same way as any other league.

Frequently asked questions
Does RotoHound handle OnRoto swingman slots and active-roster limits?
Yes. The maximum active players setting imports with the league, swing slots accept a hitter or a pitcher, and every lineup RotoHound builds respects the limit.
Can I see what the other bids on a player were?
Yes. OnRoto publishes its weekly bid log, and RotoHound’s transaction log shows the winning bid beside the runner-up bid, so an overpay is visible after the fact.
How does RotoHound score a trade?
It applies the trade to both rosters, rebuilds each team’s lineup, projects every team’s rest-of-season stats, and recalculates the league standings. The score is the change in projected standings points for each side, using your league’s exact categories or point values.
Does it work for points leagues and head-to-head?
Yes. RotoHound models rotisserie and head-to-head leagues, category and points scoring, and custom formats, including platform presets for Yahoo, ESPN, CBS, and FanGraphs points.
Where do the projections come from?
RotoHound publishes its own rest-of-season projections, updated daily. You can also upload projections from FanGraphs or any other source, and every tool uses whichever system you set as your default. The methodology page explains how the built-in projections are made and how they benchmark against Steamer and ZiPS. Read the methodology
Is RotoHound free?
Yes. RotoHound is free for the 2026 season with a free account.
