This site was created mainly for keeper leagues using an auction-based system, as it allows leagues to take as long as needed to fill their teams and it forces teams to pay for their players using a league salary cap.
There are plenty of league options available - your custom league cap, multiple minimum bidding options, multi-year player contract options, setting any length of auction clocks, allowing teams to nominate players for auction, and more.
The MLB player list on this site also includes minor league prospects.
The site is completely mobile friendly, so you can also use it on a tablet or phone.
