DFS for humans
and agents.
Build DraftKings daily fantasy lineups in minutes. Or send your agent and never open the app.

Built for serious DFS players
Everything you need to build competitive GPP lineups, without the bloat.
Simulation-Enhanced Optimizer
Monte Carlo simulation runs 10K iterations per player before the ILP solver touches a single lineup. Ceiling projections, leverage scores, and game-script awareness baked in.
Stacking and Correlation
QB+pass catcher stacks, game stacks, bring-backs. Configure correlation groups visually and let the solver enforce them hard.
Vegas-Aware Game Script
Game totals and spreads feed directly into projection adjustments. Shootout games boost pass catchers. Blowouts suppress trailing offenses.
Agent API
POST a slate, get lineups back. Skill files let any LLM agent orchestrate the full optimize-and-export workflow on your behalf. No UI required.
Priced for players and agents

Back the build
I play DFS. I also love building things. Eventually those two obsessions collided. Instead of relying on optimizers, I started building my own. Not because the tools out there are bad. But because there's nothing like using something you built yourself to find an edge.
Now I'm layering in agentic workflows: automating research, lineup construction, and iteration to see how far I can push it. If you're a DFS player who's ever had the itch to build instead of just click buttons, you get it. Follow along. Support keeps it running while I keep experimenting.

Common questions
Is the optimizer actually free?
Yes. Import a DraftKings CSV, build lineups with stacking and correlation controls, export a DraftKings-ready file. No credit card, no trial period.
What sports and contest types are supported?
NFL and NBA, both Classic and Showdown/Captain formats. DraftKings only for now.
What's the Agent API?
A REST API that lets any LLM agent — Claude, GPT, or a custom script — run the full DFS workflow: fetch slate, optimize, export CSV. We publish skill files so your agent knows exactly what to call.
When is Pro launching?
No hard date yet. Join the waitlist on the pricing page and you'll hear first. The goal is to keep free genuinely useful, not a locked-down teaser.
Can I bring my own projections?
Yes. The DraftKings CSV import respects any projections you add. The optimizer also blends them with Vegas and simulation data when enabled.
