Scoring engine and rulebook
Points, bonuses, roster rules, and postponement handling written down, coded, and tested against past seasons.
The Problem
Your Fantasy Game Breaks on the Busiest Sunday of the Season
The problems surface on draft night and the first big game day, when a script's limits, a thin data license, and untested rules show at once.
Draft night
Picks lag and two teams draft the same player.
Draft night
A real-time draft room locks each pick for every manager at once.
Scoring
A postponed game freezes scoring for the whole league.
Scoring
The scoring service follows your written rules for postponed and suspended games.
Data rights
The data license excludes the live stats players expect.
Data rights
We confirm feed coverage and live rights before any screen gets built.
Lock-in
A clone script can't change when your format does.
Lock-in
Your own code lets you add formats, sports, and contests each season.
You bought a white-label script because the demo looked finished. Then draft night came. Picks lagged as every manager clicked at once, and two teams drafted the same player. On Sunday a game was postponed, and the scoring froze for the whole league. Your data feed license turned out to exclude live stats. Players posted screenshots of wrong totals before you could fix anything. Now you're paying for a script you can't change and refunding entry credits by hand.
We start with your rules: points per stat, roster slots, draft type, trades, waivers, and what happens when a game is postponed. Then we choose a licensed data feed that covers your sport, live stats included. The draft room runs on WebSockets, so every pick appears for every manager at once. Scoring runs as its own service, tested against past seasons before launch. Draft night becomes the reason players come back.
A scoring engine you control
Points per stat, bonuses, and edge cases written as rules you can change without a rebuild.
A draft room in real time
Every pick, timer, and queue update reaches every manager instantly, even on a crowded draft night.
Live scores from licensed data
Stats stream from a licensed provider into scoring, so totals update while games are played.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built websites, apps, and platforms for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Fantasy Founders Trust Us With Draft Night
A fantasy game wins players on draft night and keeps them on game day. These habits guide every build, from rulebook to first live week.
Rules before screens
We write the full rulebook, edge cases included, before we design anything. Scoring disputes come from rules nobody wrote down, not from code.
Load tested for draft night
We simulate crowded drafts and busy game days before launch. The busiest hour of your season is the wrong time to find a bottleneck.
Licensed data only
We only build on sports data you're licensed to use, with live rights confirmed in writing. Scraped stats break, and they can bring legal letters.
Legal questions go to counsel
Paid-entry fantasy contests are regulated state by state in the US and differ abroad. We flag the questions, and your counsel answers them.
Honest about clone scripts
If a white-label script truly fits your format and budget, we'll say so before we quote. We build custom when your rules are the product.
Code and scoring you own
The code, the scoring rules, and the player data belong to you. Adding a sport or format later doesn't need anyone's permission.

Good fit
Sports media brands and publishers
Your readers already follow your player news, and you want a fantasy game that keeps them coming back all season.
Founders testing a niche format
You spotted a sport or format the big apps ignore, such as college lacrosse or esports, and need an MVP to test demand.
Cricket and soccer audiences
You want a fantasy sports app like Dream11 for a cricket or soccer audience, with contests built around match days.
Leagues and teams adding fan games
Your league or club wants an official fantasy or pick'em game for fans, tied to your own fixtures and player data.
Agencies with sports and media clients
You pitch sports and media brands and need fantasy sports app developers who can build the game under your agency's name.
Not a fit
Paid contests, no legal review
You want paid-entry contests but have no license or legal review for your markets. Get advice from counsel first, and we'll build once they sign off.
Sportsbook, not fantasy
You want odds, bet slips, and wagering on game outcomes. Our Sports Betting App Development service covers licensed sportsbook apps.
League admin for real teams
You run real teams and need registration, schedules, and standings. Our League Management Software service fits that better.
Private league for friends
You want a league for friends or the office. A free league on one of the big fantasy apps costs nothing and works well.

Fantasy builds with DeveloperLook start at $1,250 for a weekly picks game on the web. A season-long MVP with a live draft and licensed scoring starts at $4,700, and a multi-sport platform with native apps starts at $9,600. Your sports data license is billed by the provider, and it's often the biggest running cost, so we estimate it during discovery.
A weekly picks game takes 3 to 5 weeks, a season-long MVP 10 to 14 weeks, and a full platform 16 to 20 weeks. Plan backwards from your sport's season start, since launching after week one loses most sign-ups. App store review and the replay test take the last two weeks.
You create one in five stages: define the game, license the data, design the screens, build and test, then launch before the season. The rules come first, because drafts, lineups, and scoring all depend on them. Most failed launches skipped the rulebook or the data license and paid for it on draft night.
Build it as three parts: a scoring service, a real-time layer for drafts and live scores, and the web and mobile apps on top. Data from a licensed feed flows into scoring, and WebSockets push updates to every player. The backend needs load testing for draft night, when most traffic arrives at once.
To make one, you need a rulebook, a data license with live rights, a data budget, and legal advice for paid entry. With those settled, a weekly picks game can launch in weeks. Season-long leagues need more time because drafts and trades add complexity.
Build it as a web app that installs on phones, so players draft and set lineups without an app store download. Next.js with server rendering keeps player pages and news fast and indexable in search. Many founders launch web-first, then add native apps once leagues return for season two.
A fantasy football app needs football's own rules: PPR or standard scoring, bye weeks, waiver priority, and Thursday-to-Monday lineup locks. It also needs injury news fast, because lineups change minutes before kickoff. We test scoring against a full replayed NFL week before launch day.
Start with one sport, one format, and one audience you can reach cheaply, then test demand with a free-to-play game. Paid-entry contests are regulated state by state in the US and differ abroad, so get legal advice before you charge entry fees. Budget for data licensing early, because it runs every season.
Fantasy sports apps make money from entry fees on paid contests where licensed, plus ads, sponsorships, premium subscriptions, and in-app purchases. Free-to-play games usually earn from sponsors and ads, or feed traffic to a media brand. Paid contests keep a share of entry fees, which brings licensing and payout rules with it.
You own the code, the scoring rules, the player data, and the app store listings from day one. Every plan includes 45 days of bug fixes after launch, which covers the opening weeks of your season. Ongoing work after that runs on a monthly care plan or a quote per change.
