Is there a free DFS optimizer?
Yes. The DFS Studio optimizer at https://dfs.studio/optimizer is free, with no account and no card. Pick a site and a sport. Build up to 20 lineups on any open slate with your own locks, excludes, exposure caps, and stacks, and download the file for DraftKings or FanDuel. Bigger pools and the entries tools cost $3 for one slate, or $30 a month.
What is free?
- The optimizer: up to 20 lineups on any open slate, with your own locks, excludes, exposure caps, and stacks, and the file to upload on DraftKings or FanDuel.
- The top 10 players of each open slate by projection, and the top 10 by value.
- The perfect lineup of each final slate: the best lineup that was possible, by the real points.
- The open slates and their top players for an AI agent, at a free MCP server with no account.
Free DFS projections has each open slate. DFS Studio for AI agents has the free address for Claude and ChatGPT.
Does DFS Studio give a finished lineup?
No. DFS Studio does not publish a finished lineup for an open slate. You build your own with your own choices, which is also what DraftKings' rules ask of a lineup tool.
What do the paid tools add?
A slate pass or the monthly plan builds pools of more than 20 lineups, up to 5,000. It fills your DraftKings or FanDuel entries file, and late swap takes an OUT player out of your entries after lock, with alerts. It adds the contest sim, live points, and the AI agent at https://dfs.studio/mcp.
What does the full optimizer cost?
A slate pass costs $3: one payment, no plan, every tool on one slate. The monthly plan is $20 a month if you join by November 30, and $30 a month for a new member after that, with 7 days free first. How much does a DFS optimizer cost? compares the prices of the large tools.
