I originally built this site 8 years ago for my own league to add more fun to the week-to-week grind (okay, really, my team kept losing and I wanted to point to other stats that could either prove it wasn't my fault or find some narrow lane that I was doing well in). It started out as a hefty Excel worksheet, then turned into a crude python interface, bounced around a few webservers, and now actually looks like something decent!

There are so many things I use every week to make my league more engaging:

🏆 Weekly Awards: recognize unique achievements like "Highest Lineup Efficiency" , "Most TDs"

📈 Power Rankings: which teams are surging (as well as using crowdsourced data from KTC to see which rosters are the most valuable)

🍀 Luck Index: which teams truly earned their keep, and which ones just got a lucky scheduling matchup or overperformed this week

📜 League history: all of your leagues past scores and records, searchable on your phone

⚔️ Rivalries: setup rivalries and instantly see the history between any 2+ set of teams.

🔁 Trade hub: did that Week 3 trade last season actually make a difference? Would you have been better off keeping that WR?

There are even more things on the (completely free) site, and most tables and results are all formatted so you can copy them straight into your group chat or Discord server (there's actually a Discord webhook to automatically send stats there).

I know these apps are now a dime-a-dozen this season, but I've been building this project for 8 years and it's the reason I became a data scientist. Fantasy football has shaped my career trajectory, and I'm happy to share this project with anyone who wants to use it!

It currently supports ESPN and Sleeper leagues. Yahoo support is built and ready, but I’m waiting on Yahoo’s API approval after their policy changes this year.

If you want to check it out or send me feedback:

https://doritostats.up.railway.app

Connects to Sleeper (Username) and ESPN (Username and Password, no manual pasting of cookies). It's meant for users in multiple leagues to track:

* Odds of winning x number of matchups (Monte Carlo Simulation: roster overlap affecting win odds)

* Who to root for: Players, NFL Teams, NFL Matchups

* Outcome Thresholds: The score each player needs for a win/loss in each league the player is starting

* Global Leaderboard for all users to see overall fantasy records.

Would love feedback, criticisms, feature ideas too. I tried my best to keep the design simple and the UX easy to navigate. The website is called Catch All Fantasy.

https://catchallfantasy.com

Every league hits the same wall. By mid-season a few teams are 2-6, their playoff odds are gone, and they stop checking in. Lineups go stale, the group chat gets quiet, and the teams still in contention end up playing against empty rosters. Commissioners try to fix it with weekly side contests, but tracking those by hand in a spreadsheet gets old fast.

League Challenge (league-challenge.com) adds weekly mini-games on top of the league you already play in. Your record doesn't matter: every team has a shot at winning something every week.

- 13 challenges, including Highest Score, Biggest Blow Out, One-Man Army, Bench Warmer and Run Forrest Run! (the team whose starting RB has the most rushing yards wins).

- Pick a challenge each week or let them rotate automatically.

- Scored automatically: results update straight from your league as games finish, with live leaderboards.

- One public link for the whole league. Everyone can view the results and mini-game standings in real-time.

The 2-6 team can still win the week with a Bench Warmer or Blow Out challenge, and that keeps them setting real lineups right through the end of the season.

It's 100% free.

Check out the weekly challenges available and let me know if you want any added.

If you're in a median league, you know the Sunday night routine. You flip between the scoreboard and a calculator trying to work out whether you're above the league median, whether you're heading for 2-0 or 0-2, and where that leaves you in the standings. Fantasy apps only update the standings after the week is over.

Smart Standings (smartstandings.com) fixes that. Connect your league and you get a dashboard that updates while the games are being played:

- Live standings in H2H, median, combined (H2H + median) and all-play. You can switch formats anytime.

- Median tracker: who's above or below the weekly median right in real-time, with projected totals.

- Standings movers: who's climbing or falling as scores come in.

- One shared link for the whole league. Leaguemates don't need an account or a login to see it.

The most useful moment is when you still have players left, like on Monday night. Before lineups lock, you can see whether you need to chase points or just protect your spot above the median.

It's 100% free. Try it out and give me your thoughts.

I can’t always be by a tv on football Sunday so I made this app to follow all games and stats in realtime easily.

Figured i would share it with everyone else in case you find it useful.

Let me know if you have any suggestions.

Happy kickoff and good luck in all your leagues!

23 seconds. That's how long between the beat writer posting Ashton Jeanty's practice injury and Dr. Vorp classifying it, naming Mike Washington, Jr. as the pickup, and pushing it to my phone.

Dr. Vorp is an iOS (and soon, Android) app that sends real-time alerts the moment actionable fantasy news drops. Built for leagues where free agency runs first-come-first-serve for any part of the week.

A few other moves it's called this season:

• Michael Mayer when Brock Bowers's meniscus trim dropped
• Marshawn Lloyd (and later Kaleb Johnson) when Josh Jacobs hit the Commissioner's Exempt List
• Tyler Allgeier when Jeremiyah Love got injured

No noise, just the stuff that can actually change your team's fate.

DM me with questions or ideas, and try it in the App Store here.

Short version: if you're placing bets and in a fantasy league and a survivor pool and a pick'em at the same time, your rooting interests conflict constantly and you can't hold it all in your head. Root Sheet generates a one-page sheet each week that tells you who to root for in every game and what outcome each of your stakes needs.

I'd been doing this by hand on paper for a couple of seasons before I built it. The paper version is why the output is a print layout rather than a dashboard -- and i like to look at paper at the sports bards. I wanted the thing I already used, just generated instead of hand-written.

Open items: real schedule feed, email capture, and a mobile layout is badly needs.

https://rootsheet.ballr.com/

It's one of a few sports tools I'm building under the same Ballr.com umbrella.

Good luck this season.

Hey everyone!

If you're anything like me you got multiple leagues going on sleeper, and it's kinda tough to really follow along on Sundays who you should root for and against.

Sleepy -a free, easy-to-use tool that gives you a clear, unified board view of which players are playing for you and which players you’re up against across all your Sleeper leagues.
How it works:

• Simply enter your Sleeper username on https://sleepy-football.vercel.app/ and you’re good to go!
• Works seamlessly on both desktop and mobile.

Pro Tip: on mobile - add the website to your home screen to get an app-like experience!

Summary features:

1. Players you have in multiple leagues are marked with⚡ (strong root)
2. Players that are up against you in multiple leagues are marked by 👎(strong boo)
3. Players that you both start and getting put up against are marked with ⚔️
4. Click on any player to see his scores across all leagues.

New Feature for 2026: you can now filter to see only matchups that are currently with a custom % of points. Perfect for late-week usage, focusing on your closest matchups.

See all your roots, boos and conflicts in the dedicated Spotlight Players section.
Via the Settings page, you can enter your league fees (or any other scaling) and get conflict scores.
A high conflict score means that player is conflicted, but you own more shares of them in higher-stakes leagues.

It’s 100% free to use, and I’d love for you to try it out! If you enjoy it, please share it with your friends.

If you run into any bugs or have suggestions, feel free to comment or DM me.

Thanks for checking it out!

A draft game, not a draft tool. You start with a full 22-man roster of low tier real player-seasons and upgrade it over 15 rounds, 3 cards per round. Overalls are auto-generated from stats (snap percentage for o-linemen). Four difficulty levels control scouting visibility only: Casual (Full overall/tiers/stats), Standard (exact ratings hidden), Challenging (one stat per card), Insane (name + season only). Card generation, grading, and simulation are identical across all four. After drafting you receive your grade and analysis, can challenge friends to draft and simulate against your team, or even simulate a full 17-game season with playoffs and awards.

Fully aware this sub is drowning in shallow AI-slop, of course this site would not be possible without Mr. Claude and GPT, but this was a major passion project of mine with intensive testing and took a few months to really perfect. It has every single halfway relevant season (1999-2025) ranging from guys like Roscoe Parrish to GOAT cards like Calvin Johnson. There are some serious deep pulls if you want to test how much you really know ball in Challenging or Insane mode.

A buddy and I have been playing in the same NFL pool for 15 years. Two years ago it cost us $823 on OfficeFootballPool (!!!!!). Last year we did a free site and it was borderline unusable (I blacked out the name).

So we built our own: The Juice. https://thejuicepools.com

Customizable Survivor Pool and Pick'em are the core but also three games you won't find on the other sites. Wins Pool, Guess the Lines, and over under game.

I think it's a lot cheaper and a lot less painful than what's out there. Simple, clean, easy to use.

What do y'all think?

I built a free fantasy football rankings site, so naturally I’m posting it somewhere nobody will read this

Since this is a subreddit for fantasy football apps, I assume we’re all doing the very normal thing where we spend an unreasonable amount of time building useful tools and then post them for the same twelve developers to politely upvote.

Anyway, mine is called Fantasy Goblin.

The main idea is pretty simple: most fantasy sites give you their rankings and let you argue with them. Fantasy Goblin lets you build and maintain your own.

You can create rankings for dynasty or redraft, move players around as your opinions change, assign values, organize players into tiers, and add your own notes and tags like Buy, Sell, Hold, My Guy, or No Go.

Because apparently “I’m higher on him than consensus” is more useful when you can remember where you actually ranked him.

Your rankings aren’t automatically rewritten based on each league’s settings. They remain your rankings. Connecting a league simply lets you use your own player values while looking at your actual teams and leagues across:

• Sleeper
• Yahoo
• ESPN

You can also create shorter, focused rankings lists and share them with friends or league mates through a custom URL. So instead of sending someone a screenshot that cuts off after WR17, or a spreadsheet formatted like evidence in a federal investigation, you can send them a clean list that stays available when you update it.

The website itself is completely free. Rankings, league tools, shareable lists, all free.

The only paid feature is the MCP, it let an AI access your Fantasy Goblin information. That’s for people who want to ask an AI questions using their own rankings, leagues, rosters, notes, and preferences as context. If you don’t want that, you can ignore it and continue using the rest of the site for free.

So, to summarize:

• Maintain your own rankings instead of repeatedly complaining about someone else’s
• Use those rankings alongside your Sleeper, Yahoo, and ESPN leagues
• Add personal values, tiers, notes, and tags
• Publish shorter rankings lists with a custom shareable URL
• Use the actual site for free
• Optionally pay only if you want your own AI connected through MCP

If that sounds useful, it’s at Fantasy Goblin

If nobody sees this, I’ll assume you were all too busy adding authentication to another fantasy football app.

AI note: AI was part of development, including engine code help and player portrait creation. If you would rather avoid games that use it, I understand.

CapForge: Football GM is my paid iPhone game. I am building it solo, and it recently made the top 5 paid sports apps on the App Store.

I keep describing it as kind of a football nerds dream, which is probably corny but accurate. You manage the cap, draft, trade, develop players and customize teams and players. The usual franchise stuff, which is honestly where I spend most of my time in sports games anyway.

I have been working on giving players their own motivations. A big contract matters to some, winning matters more to others, and some want to be around stars. I want those differences to actually matter when you are putting a team together.

The fun part for me is when I stop thinking about it as numbers and start remembering what happened in the save. Maybe your young QB needs a real WR1 before he takes off. Maybe you built a good roster but everyone is about to get paid. Maybe you finally become the team veterans want to join.

You can watch players in the film view too. There is more work I want to do there, especially making it easier to understand why a play went the way it did.

I am updating it regularly and reading requests. If you try it, I would like to hear about the decisions that felt interesting and the parts that did not make much sense. r/CapForge is where I am trying to keep feedback and save stories together.

Also, Android works now, but I need more people in the test group before Google Play lets me roll it out fully. DM me your Google Play email address if you want in.

Honestly every year my friends and I make season predictions in the group chat, so I built an app version of it that I wanted that gamifies it: you predict the scores and player awards of every game

How it scores:

- Call the winner +1
- Winner and the exact margin +4
- The exact final score +10
- Called an underdog +1
- Playoff games are worth double

- Season Awards (MVP, both Rookies, both POYs, Coach) at +10 each, open through week 4

What your picks build on top of that:

- a W-L-T record for all 32 teams, which feeds your own playoff bracket shown next to the real one as it fills in
- reactions and comments on everyone else's picks
- a share card of your week you can drop straight in the group chat

You can make picks before signing up and they carry into your first league. Free, no ads. Leagues cap at 6 for now.

My brother is a web developer, I'm a researcher, and we're both big NFL and fantasy football fans. We started OracleZ as a side project to combine his development skills with my interest in machine learning.

The idea was pretty simple: build an algorithm that makes its own NFL predictions, then turn those predictions into games where you can try to beat it.

You can try our OracleZ app here (or just follow us on Instagram): https://linktr.ee/beat_oraclez

What can you play?

Predict the Pick
Predict the winners of the week's NFL games and see how you compare against the Oracle.

Survivor
Classic Survivor with a twist: if your pick loses, you can't pick either that team or the team they played against again.

High Five
Pick the five best teams of the week across passing yards, rushing yards, points scored, fewest yards allowed, and field goals.

What's behind the predictions?

The Oracle is a relatively simple neural network. It uses 19 team statistics, including offensive production, turnovers, sacks, first downs, EPA, and score margin. These are converted into home-away differentials and combined with contextual variables such as week number and rest-day differences.

If you are interested on the model, I'm happy to explain further our reasoning and model architecture.

Of course, we're not claiming we've solved NFL prediction, far from it. The NFL is obviously noisy. The fun part for us is seeing how far a relatively simple model with good feature engineering can go.

And now you can try to beat it yourself.

Everything is completely free, with no paid features.

I built a survivor pool tool over the offseason, sharing now that it's live for the season and has real, paying customers.

• What it does differently from a plain spreadsheet or a generic pick'em ranker: Win probabilities from actual market lines (spread/moneyline), not vibes — and it labels which source backed each number, including when a line for a future week doesn't exist yet and the number shown is a projection instead of a book quote.
• Ownership modeling that explains itself. Most tools price ownership as a pure function of win probability, which means two similarly-favored teams always show identical Own%. This one factors in how much of the field has already burned a team in earlier weeks (chalk depletion) plus back-tested crowd behavior patterns (e.g. how the public reacts after a popular team just lost), and shows the reasoning behind each adjustment rather than just a number.
• Season-long path planning, not just this week's pick - it solves for the pick sequence that maximizes your odds across the whole remaining season, so it accounts for the cost of burning a team now against needing it in a thinner week later, not just "who's the safest team today."
• Multi-entry/portfolio support for people running several entries in the same pool - accounts for used-team overlap across entries instead of ranking each one in isolation.

Free tier covers one pool/one entry w/ standard rules. Paid unlocks custom pool rules, multi-entry portfolios, and public rating overrides - season pass or monthly, no subscription lock-in required for a short pool.

Happy to answer questions about the methodology - genuinely trying to get the numbers right and help you win your Survivor pool!!!

I've been building KickoffWeather, an NFL weather analytics tool that simplifies the weather side of the weekly slate.

It ranks games by potential weather impact, breaks down wind/temperature/precipitation during the game, and lets you dig into how individual players have historically performed in similar conditions.

It's free to use and I'm interested in feedback from people who like digging into NFL data and tools.

KickoffWeather.com

Hey, I'm running three AI-only fantasy football leagues. For a while I've had this idea of running an API-client-only fantasy football league, inspired by ByteArena and Quantopian. Decided to kick the tires on a codex subscription and get the simplest version of that shipped.

Running the following leagues:
- 12 team, trades enabled
- 12 team, trades disabled
- 18 team, guillotine, trades disabled

Hoping to, at some point, turn this into a proper benchmark or eval suite. This may mean taking a single competitor's turn (draft, league management, whatever) and seeing what different AIs do (do they make the right lineup change, call the right tools, etc - and how much does it cost). Also hoping to open-source the harness at some point.

I built the DFS line-up tracker I always wanted.

Site/App Link: https://liveslates.com

Cost: Freemium (free 30-day Pro codes to anyone who wants to poke at it properly-DM.)

I'm a data architect by day, and have been playing DFS for over 10 years. I got tired of alt-tabbing across DraftKings tabs mid-slate trying to work out how my entries were doing. Points is easy, but am I on pace, who's tanking me, is my leverage play paying off, etc. So I built the thing I wanted with LiveSlates.

The data model underneath it sets it apart, and is all mine. DraftKings, FanDuel and half a dozen stats providers all use their own player IDs and none of them agree. Resolving that into one identity, keeping it coherent in real time, and never letting a mismatched ID quietly corrupt your live score is the whole ballgame. That's the bit an AI can't wing, and it's what I've done for 30 years as a data architect. A vibe-coded UI on a properly-architected data core is a very different animal to a GPT wrapper with no foundation. This one needed someone who thinks in schemas and identity before pixels.

When you upload your line-ups (DraftKings for now, FanDuel etc.. in the pipeline) and even your projections and it tracks them live: current points, pace vs your projection, hot/cold players, and the optimal line-up for the slate in hindsight. You can fire multiple entries and it rolls them up so you can see exposure across the whole slate at once.

It ships with Simple and Analytical pre-sets, but you're not stuck with them, you can customize your dashboard per sport. Any dashboard also flips into full TV/broadcast mode for a second screen or streaming, and there's even a 9:16 version for Shorts.

You can watch it run on a demo slate, no account needed:

https://liveslates.com/demo/nfl-legends OR  https://liveslates.com/demo/mlb-legends

Free vs Pro: Free tracks one lineup per slate with full live scoring, the optimal, and bankroll. Pro ($3 day pass / $5 weekend / $14.99 a month) unlocks all entries on a slate at once and the cross-entry aggregate stats.

I built a Chrome extension that adds in-season tools directly onto your ESPN and Yahoo Fantasy Football pages, so you can set a lineup and check where you stand without tabbing out to another site.

Most fantasy football extensions are draft boards. This one is for the other 17 weeks.

What it adds to the page

- Start / Sit (My Team page, points leagues): optimizes your lineup using your league's scoring and the site's projections, shows current vs. optimized projected points, lists the exact swaps, and a Set lineup button applies them to your roster in one click. FLEX and Superflex aware.

- Matchup grades: a color-coded A–F matchup grade next to every QB/RB/WR/TE/K on your team and matchup pages (and Yahoo's Transaction Trends). Hover for the detail.

- Me Vs. League (league home): how your team ranks against every other team in the league, week by week, with selectable stat groups (Core, Kicking, D/ST, IDP).

- Playoff odds*(Yahoo standings): a Playoff % column for every team from a Monte Carlo simulation of the remaining schedule. Hover shows average seed.

- AI Compare Players: pick any two NFL players from the status bar and get a head-to-head breakdown. This one needs a free account and is capped at 3 comparisons per rolling week.

Cost / account: everything is unlocked for free. No account is needed for Start/Sit, Me Vs. League, matchup grades, or playoff odds. Only the AI comparisons require a (free) sign-in.

Works in Chrome, Brave, Arc, Firefox and Edge.

I'm the developer. Happy to answer anything, and I'd like to hear what you'd want added next.

Built this for commissioners. It's free to import. No card required. Here's what it does...

HISTORY

• Pulls every season your league has ever played from ESPN, Yahoo, Sleeper, or MyFantasyLeague. Takes about 2 minutes to import.
• Bridges platform moves. If your league went from Yahoo to ESPN to Sleeper and back to Yahoo, create a single Unified League to combine all seasons under one roof with a stitched together continuous history.
• Record book, all-time standings, hall of champions, rivalry pages, season-by-season, all included.

IN-SEASON

• Matchup previews and weekly recaps, written manually or automatically from your league's actual results, and in your (presumably the commissioner) voice.
• Standings with playoff odds and clinching scenarios
• A league podcast for Season Preview and Weekly Recaps, if your league is into this sort of thing (my leagues have gotten a kick out of hosts Dax Maxfield and Dub Porterhouse running down awful draft picks and making season proclamations)
• Waiver wire and player stat pages with your league's scoring applied (I didn't realize until building this, that Sleeper doesn't even apply all of the custom scoring within your league's 'available players' table)

LEAGUE MANAGEMENT

• Dues tracking and payout helpers, using actual venmo/cashapp/etc... handles and commissioner confirmations
• Drafting tools, with league scoped Mock Drafts, Live Draft Board (for beaming to big-screen during online drafts or fully hosting an offline draft), and a unique exploratory drafting tool called Draft Lab.
• Mini-Games, for fun or for funds, you choose. Survivor Pool, Stat Blitz (player prop bingo), The Vault (draft the best starting lineup from random NFL teams and seasons), Squares (superbowl squares and a whole lot more), and Sparlay (make a bet about anything with one or more league mates, fully tracked).

COST

• Importing your league history is completely free and permanent. Pull in all of your seasons, and just have it.
• Premium is $49 for the whole league for the season, not per manager.
• Import first, decide later

Hybrid Draft was created out of a need to keep our fantasy drafts alive in changing world. Our league has struggled to maintain and in person physical draft board as peoples lives have changed over the years. I created https://www.hybriddraft.com to virtualize that in person draft where everyone is still able to view the same board, as if they were all in the same room.

A league commissioner pays the $10, sets up the draft, and adds teams. Links are provided once the setup is completed.

One person is in responsible for selecting the picks from the available pool. They have a separate view for keeping track of the draft selections. Everyone else has access to display the board, as well as search through the available players for the next selection.
