Built by a DFS player, for DFS players.
DFS War Room started out of pure frustration. Like thousands of DFS players, we were tired of paying $30–$50 a month for optimizer tools that were either too complicated to use, locked the best features behind paywalls, or just didn't work the way we needed them to.
We're based in Davenport, FL — not Silicon Valley. We're not a venture-backed startup with a team of 50 engineers. We're DFS players who got tired of the status quo and decided to build something better. Something free. Something that actually works the way a GPP grinder needs it to work.
DFS War Room was built from the ground up with one goal: give every DFS player — whether you're a beginner or a seasoned GPP grinder — access to the same powerful lineup optimization tools that the pros use, completely free of charge.
"To democratize access to professional-grade DFS optimization tools and give every player — regardless of budget — a real shot at winning GPP tournaments."

DFS War Room is free because we believe powerful tools shouldn't be locked behind paywalls. We fund the site through non-intrusive Google AdSense advertisements — the ads you see on the page help us keep the lights on and the optimizer running for free.
We're working toward a goal of 25,000 subscribers, at which point we plan to unlock premium features — including real-time player news integration, advanced exposure controls, and multi-slate optimization. But the core optimizer will always remain free.
Have questions, suggestions, or feedback? We read every email and genuinely want to hear from our users. If something isn't working right or you have an idea that would make the tool better, reach out.
