The Goal
League-specific analysis for
Dynasty Fantasy Football.
The goal of Gridiron.io is simple: provide tools tailored to your league. No generic redraft advice, no one-size-fits-all rankings. We ingest your specific Sleeper league settings and use AI to give you personalized dynasty strategy and trade analysis.
Why we built a dedicated Sleeper dynasty assistant
Gridiron.io was created to solve the problem of generic dynasty advice by building an AI assistant that directly ingests your specific Sleeper league scoring rules. It calculates accurate player values, age curves, and trade grades tailored strictly for your unique dynasty league.
Hey there! I'm Isaac, a solo developer with a passion for Dynasty Fantasy Football. Like a lot of you, I spend way too much time thinking about age curves, rookie draft capital, and how to squeeze out an extra 5% of value in a trade.
I was frustrated by the lack of tools that factored in my league's specific scoring and roster rules. I wanted something custom-built for my leagues rather than generic market consensus. So, I decided to build it myself.
Gridiron.io is the result. It's a suite of custom tools that I built from the ground up, using AI to evaluate your live Sleeper data. I built this to win my own leagues, and I'm excited to share it so you can win yours, too.
Dynasty Analysis Built for Your League
Most fantasy tools give generic advice. Gridiron.io ingests your specific league, including your scoring rules, your roster, and your history, then reasons from that ground truth.
Built for Dynasty
Redraft advice is easy. Dynasty requires a 3-year outlook, age curve analysis, draft capital valuation, and deep positional understanding. That is all we focus on.
Your Data Stays Yours
We connect to Sleeper's public API and store only what's needed to power the product. We never sell or share your league data.
