SaberSim is the premier daily fantasy lineup builder & analysis tool. Using advanced data & metrics, users can build individual rosters or entire portfolios for DFS contests, from Head-To-Heads & Double-Ups to the biggest Guaranteed Prize Pool multi-entry tournaments.

SaberSim uses custom logic with a myriad of user-adjustable settings & rules to tailor your DFS lineups to your individual playing style and contest selection. 

With a TrueDFS+SaberSim membership, subscribers get exclusive access to TrueDFS advanced projection sets to use in the SaberSim lineup builder. We automatically upload our fantasy point & rostership projections directly to the builder so you can create lineups quickly & efficiently.

The subscription comes in three flavors, one for any level of DFS enthusiast, from novice to high-volume grinder:

• TrueDFS+SaberSim CORE
  • Best for entry-level players or those that play just a few lineups
  • Includes TrueDFS projections
• TrueDFS+SaberSim STARTER
  • Best for those ready to expand their play surface to many lineups and game+contest types
  • Includes SaberSim projections
• TrueDFS+SaberSim ULTIMATE
  • Best for serious high-volume players
  • Includes SaberSim Contest Sims

See our membership page for pricing and more details.

SaberSim Classic is a legacy implementation of lineup-selection logic & visualization. It has been superseded by Lineup Groups in the newest version of SaberSim, which is a modern & advanced way to organize your lineup portfolio.

For those not yet fluent with Lineup Groups, TrueDFS and SaberSim provide Classic as a battle-tested alternative. We recommend getting familiar with the newest version as soon as possible as Classic is only supported for a limited time. 

Find both versions in the SaberSim navigation bar dropdown at the top of the page.

Saber School is SaberSim's documentation & training hub, with everything you need to get familiar with the builder and take your play to the next level. It includes daily Office Hours recordings, where the SaberSim team answers community questions, as well as tutorials & walkthroughs of the app.

You can access the hub via the Saber School link in the top-left corner of the builder.
