SimLeaguesPro - The Online Sports Simulation and Fantasy Leagues Web Site!

SimLeaguesPro — The Online League Operating System

Hi everyone! Over the past year I've been building SimLeaguesPro, a new cloud platform designed to improve the overall experience of running and participating in online OOTP leagues. The website is now approaching its 1.0 release, and I'm happy to be sharing it with the community.

What is SimLeaguesPro?

SimLeaguesPro is the official successor to OOTP Fantasy Leagues, rebuilt from the ground up as a modern cloud platform. But it's grown into something much bigger than fantasy baseball.

The goal isn't to replace the tools leagues already use today.

Instead, SimLeaguesPro is designed to work alongside Stats+, with each platform focusing on what it does best.


Stats+

• League statistics
• Reports
• Historical data
• Statistical analysis
• Trade and Draft Analysis

SimLeaguesPro

• League identity
• Owner engagement
• Community
• League news and content
• League discovery
• Recruiting new owners
• Team owner tools
• Fantasy baseball
• Optional cloud-based league file hosting and report publishing

Together they create a more complete online league experience than either platform provides alone.

How SimLeaguesPro Helps Your League.

League Websites & Publishing
Create a modern home for your league with public league pages, standings, schedules, news, scoreboards, league information and more.

League Discovery & Recruiting Publish your league in the SimLeaguesPro League Directory, advertise open teams, accept join requests, and help prospective owners discover your league.

Owner Experience
Give owners a better experience between sims with personalized dashboards, league news, notifications, export tracking, team information, and new opportunities to keep league activity thriving between sims.

Commissioner Tools
Manage seasons, upload league exports, publish new sims, distribute league files and reports with optional cloud storage, and keep your league running from a single streamlined interface.

Fantasy Baseball
The original OOTP Fantasy Leagues has been completely rebuilt with modern commissioner tools, improved league management, and year-round fantasy play tied directly to online league activity.

Built Around One Simple Goal

One thing became very clear while building SimLeaguesPro. Most online leagues don't struggle because they lack statistics or statistical analysis tools.

They struggle with keeping owners engaged between sims, recruiting replacements when teams open up, and giving members a place that feels like home.

That's what SimLeaguesPro is designed to solve.

Hey everyone!

I’m excited to share that SimLeaguesPro, is in its final beta, and we’re getting ready to run a short test season to put everything through its paces!

What is SimLeaguesPro?
It’s the successor to my old OOTP Fantasy Leagues mod, completely rebuilt from the ground up as a modern hub for OOTP (and potentially other sim sports games) online leagues.

Key Features:

• League promotion, recruiting, and member management tools
• Social-style newsfeeds and updates
• Team-owner clubhouse areas
• Public-facing league websites for fans
• Built-in hosting for league files, HTML reports, and team exports
• Run fantasy leagues off your online league at any time during the season

We’re Recruiting for a Beta Test Season!

We’re looking for users to help test the platform with a short season:

• ~35–40 games (about 4–6 in-game weeks)
• Focus on testing league operations and site performance
• Open roles:
  • Team Owners
  • Beta Testers

Never Beta tested before? No problem! We have full instructions and helpful guides available for first time participants and testers.

If your a fan or regular member of OOTP online leagues and want to help shape something new, we’d love to have you involved!

Get Involved:
Theres tons more info over at the official Discord: https://discord.gg/q6y3wbCZP including more descriptions of the features, how to join the beta and much more!

If you remember the old Fantasy Leagues mod—or wished it was still around—this site is built for you! Don't miss it!

Thanks, and hope to see you in the test season!

I should share a few things about the beta.

Online League Test Season

• Hoping to run it in OOTP 27, so must have a copy to participate (I might run a quick follow up in v26 and possibly v25 also to test backward compatibility, but that is tbd)
• This will be just a super simple season, just a 30-40 game season (4-8 sims in the game).
• Minimal OOTP in-game effort needed. Adjust rosters. Move people on/off DL.
• IMPORTANT - Export team update before each sim.
• Goals are to:
  • Assure League File exports work, are complete and accessible to all game members on the site.
  • Assure team exports work and post to server
  • Test export tracking works and is correct
  • Test League Commish (me) can import team exports and run subsequent sims
  • Verify HTML reports work, update after each sim and all links in the site to them work as expected
  • Test the social newsfeed features work correctly in the members only and public game spaces

Fantasy League Testing

• NO OOTP game required! Can simply join the site, select a league and team and play fantasy!
• There'will be a fantasy draft to participate in (they are run offline via email but we'll coordinate via Discord).
• Draft pick trading is ALLOWED and can be tested.
• Make roster moves before each sim. Add/Drop make players active, etc.
• Can propose and make player trades
• Verify sim processing works correctly
• Test playoff setting work for head to head leagues

Interested? Head over to the Discord https://discord.gg/ff6ACanBm for more details and the steps to get started with the project and join the beta.

Feel free to ask me any questions as well!

I’ve posted a major update to the SimLeaguesPro website with expanded information, screenshots, and details about the platform and how it can help online leagues with hosting, recruitment, commissioner tools, file distribution, and integrated fantasy leagues.


I’m also looking for an established online league interested in serving as pilot league and using the platform completely free in exchange for feedback.
If your league is interested in trying a cloud-based platform to help run and grow your league, this is a great opportunity to get involved early.


For information about the pilot program, please see my thread in the Online Leagues forum, join the Discord or message me directly!


Thanks to everyone who has provided feedback and encouragement during development. I’m excited to start opening the platform to the community.

I just published Part 1 of a new blog series: SimLeaguesPro – The Road to 1.0.


This first article explains what SimLeaguesPro is, why I decided to build it, and the gap it is designed to fill in the online league world.


If you’ve ever run an OOTP online league, you know the routine:

• Forums for recruiting
• Discord for communication
• FTP for league files
• Stats+ or StatsLab for stats
• Custom Web sites for news, content and engagement
• And a lot of manual Commissioner work to hold everything together

SimLeaguesPro is being built to bring the online league experience together into one platform for:

• League discovery and recruitment
• Fully integrated fantasy leagues
• Community engagement and social news features
• Links to your stats tools to enable connectivity and engagement
• Fantasy play year round!
• League hosting and operations
• Team owner tools

This article is the introduction to the series leading up to the 1.0 launch.

Read Part 1 here:
https://www.jfox015.com/2026/05/24/i...ague-platform/


I’d love to hear your thoughts:

• What is the biggest headache in running an online league?
• What would your ideal league platform include?
• What tools are you using today?

Part 2 will dive more into the commissioner tools and league hosting features.

[ootpFox07]

Part 2 of the SimLeaguesPro Road to 1.0 series is now live.

This one focuses on something every online league commissioner understands all too well:

The reality of running an online league.

After years of seeing how leagues operate—and running a league myself—one thing became obvious:

Commissioners need tools that make league management feel less like a second full-time job.

This article explores how SimLeaguesPro approaches:

• League hosting
• Commissioner operations
• Recruitment
• Member management
• Community tools
• Cloud file and report hosting
• Export tracking

All as part of a larger vision:
The Online League Operating System.

Just as importantly, SimLeaguesPro is designed to work alongside existing tools like Stats+, helping leagues become more active, connected, and easier to run.

I'd genuinely love feedback from commissioners and league owners:

• What's your biggest league management headache?
• What takes the most time each season that you'd love to see improved or automated?
• What tools or workflows are still missing from the ecosystem?

Appreciate all the support and feedback from the OOTP community.

One realization has shaped a lot of SimLeaguesPro's direction:


Most online leagues only feel active for a few minutes after each sim.
Then activity fades until the next export deadline.


This article explores why the real online league experience happens between sims and how I'm designing SimLeaguesPro to help leagues stay active, visible, and connected throughout the week.


https://www.jfox015.com/2026/06/08/o...ue-experience/

Would love to hear how your leagues keep owners engaged between sims. Your feedback contributes directly to the future of SimLeaguesPro.

Solving the Biggest Problem in Online Leagues: Finding Owners!

One challenge every online league eventually faces is owner turnover.

People get busy. Interests change. Teams become inactive.

In Part 4 of the Road to 1.0 series, I explore why recruiting replacement owners remains one of the biggest challenges facing commissioners and how SimLeaguesPro is being built to improve league discovery, visibility, and recruitment.

As always, I'd love to hear how your league handles recruitment and owner retention and what would help make life easier for everyone in that regard
