About SimLeaguesPro
SimLeaguesPro exists to give every online sim league the modern home it deserves — and to keep the communities behind them alive long after the sim ends.
Built by Sim Players, for Sim Players
SimLeaguesPro started as an upgrade to the original OOTP Fantasy Leagues mod — a fun but aging way for OOTP sim leagues to run fantasy leagues from their players and stats online. We took everything that made it work and rebuilt it from the ground up: modern infrastructure, flexible game support, real community tools, and a platform designed around the actual workflow of running a league.
We've been commissioners, team owners, and fantasy players — obsessed with games like OOTP — long enough to know what the tools get wrong. SimLeaguesPro is the platform we always wanted — and we're building it with the community every step of the way.
The principles behind every decision we make
Commissioners shouldn't run servers
Your job is to run a great league, not manage infrastructure. We handle the platform so you can focus on the game.
Owners deserve easy access to their data
Standings, rosters, stats, news — all of it should be a click away, not buried in a Discord thread or a shared spreadsheet.
Community matters as much as stats
A great league is more than a schedule and a standings page. It's the banter, the stories, the long-running rivalries. We build for that too.
Platforms should adapt to leagues
Not the other way around. Every league is different — fictional, historical, dynasty, fantasy. The platform should flex to fit, not force a template.
We're on Discord — and you should be too.
The SimLeaguesPro Discord is the home base for our growing community of beta testers, commissioners, and sim league fans. It's also a community space where commissioners share league setups and trade ideas, owners talk shop, beta testers flag bugs, and new features get announced first. If you're serious about sim leagues, this is the room to be in.
