DFS Lineup Optimizer for DraftKings

If you searched for a DFS lineup optimizer, this is ours. We call it the Lineup Generator. It builds daily fantasy lineups for DraftKings, every one under the salary cap and inside the site's roster rules, and hands you a file to upload where you entered.

What a DFS lineup optimizer does

One lineup is quick to build by hand. A tournament that takes a hundred and fifty entries is a different job: a hundred and fifty lineups, each one valid, no two the same. A lineup optimizer does that job for you. Some people call it a lineup builder or a lineup generator. It is the same tool.

The Lineup Generator builds up to 150 lineups in one pass. Our projections are built in, so there is no spreadsheet to find and nothing to upload but the entries file from DraftKings. It never signs in to your account and never places an entry. You do that yourself, with your own money.

Every sport and format it covers

Each one has its own page, with the formats and the steps for that sport.

• DraftKings lineup optimizer: NFL, MLB and NBA, in Classic and Showdown.
• NFL lineup optimizer: every slate we publish, from the Sunday main slate to a Monday night Showdown.
• MLB lineup optimizer: the slates we publish each day of the season.
• NBA lineup optimizer: DraftKings Classic and Showdown.
• Showdown lineup builder: lineups built from a single game.

What you control

Every setting starts on a default, so a first build needs no setup. Change only the ones you care about.

• Lock a player into every lineup, or ban one from all of them.
• Cap how often a player appears across the set, and set a floor for one you want in.
• Stack players you want in the same lineup.
• Swap any player on a finished lineup by hand before you download.
• Read why each lineup was picked.

How to use it

• Enter your contests on DraftKings, then download the entries file.
• Drop the file into the Generator and build. Every entry comes back with its own lineup.
• Download the finished file and upload it where you entered. The entries fill together.
