Best DFS Lineup Optimizers (2026): An Honest Comparison
Six tools show up when you search for a DFS lineup optimizer: SaberSim, Stokastic, RotoWire, FantasyLabs, Daily Fantasy Fuel, and us. We built FantasySportsEdge, so weigh our angle accordingly. What follows is what each one actually costs and does, checked against their own pricing pages on 2026-08-18.
If you want free, unlimited lineups across NBA, WNBA, MLB, and NFL with no card on file, that's us. If you want tournament simulations from a team built around GPP modeling, pay for SaberSim or Stokastic. If you only play NFL and want one free lineup, RotoWire and Daily Fantasy Fuel both have that too.

Is FantasySportsEdge actually free?
Yes. Sign in with a free account and every lineup builder is open: NBA, WNBA, MLB, and NFL, classic and single-game slates, unlimited generations, no card required. That's the whole pitch. What we don't have: no ownership-projection sims, no player-prop tools, no betting content. If you're chasing any of that, one of the five tools below does it better than we do.
What does SaberSim cost, and is it worth it?
SaberSim starts at $97 a month for its Starter tier, billed monthly, with a $7 trial for the first week. It covers 17 sports and esports categories including WNBA, and its pitch is built on tournament simulations rather than single-point projections. That's a real edge if you play large-field GPPs and want a diverse pool of lineups built fast. It's not built for someone who wants to check one lineup for free.
What does Stokastic charge?
We couldn't find a reliable number. Stokastic's pricing page and signup flow render through JavaScript with no price text in the page itself, and the third-party numbers we found for its All Access tiers didn't agree with each other. Stokastic covers NFL, NBA, MLB, NHL, WNBA, PGA, college football, NASCAR, and MMA, and its own copy positions it around projections, ownership, and simulations, the same category as SaberSim. If price matters to you, check their signup flow directly. We're not going to publish a guess.
Is RotoWire's DFS optimizer free?
The NFL optimizer is; RotoWire says so on the page itself. Everything past that sits behind a subscription: $49.99 a month for the Daily Fantasy tier, or $24.99 a month billed annually, which also covers MLB, NBA, NHL, soccer, golf, college football, college basketball, and WNBA. RotoWire's angle is breadth: season-long tools, DFS, and betting content in one account, at a lower price than SaberSim or Stokastic.
Is FantasyLabs still around, and what does it do?
Yes, and it covers ten sports including WNBA, NFL, NBA, MLB, NHL, PGA, MMA, NASCAR, college football, and college basketball. Its pricing isn't published anywhere on the site; it's sold sport by sport through a signup flow, so we're not publishing a number we can't confirm. What it's built for: Player Models and SimLabs backtesting, so you build and test your own projections instead of trusting someone else's. We couldn't find a genuinely free tool; the trends page we checked pushes a paid trial with no free path.
Is Daily Fantasy Fuel free?
Partly. Its free NFL lineup generator is real; Daily Fantasy Fuel's own site describes it as free, and it includes live odds, injuries, and starting lineups. Premium, $24 a month or $109 for six months, adds bulk lineup generation (150 at a time), saving and exporting large lineup sets, advanced stacking, and custom projection uploads. It also runs player-prop optimizers for PrizePicks and Underdog, which we don't have. It covers NFL, NBA, MLB, NHL, WNBA, and golf.
The honest bottom line
None of these five lack WNBA coverage, so if that's your filter, it won't narrow the field. What actually separates them is price and whether the free version does anything real. SaberSim and Stokastic are built for GPP simulation and charge accordingly. RotoWire and Daily Fantasy Fuel give away one free lineup and charge for scale, prop tools, or betting content. FantasyLabs charges for the ability to build your own model. We give away the full multi-sport builder and don't have the sims, props, or model-building tools the others do.
Pick based on what you actually need, not which page ranked first.
Common questions
- Which DFS lineup optimizer is actually free?
- FantasySportsEdge is the only one here with a full, unlimited free builder across every sport it covers. RotoWire and Daily Fantasy Fuel each give away one free NFL lineup; everything past that on either site, and everything on SaberSim, Stokastic, and FantasyLabs, is paid.
- Do any of these cover WNBA?
- All six, including us. WNBA coverage doesn't narrow the field, so don't use it as your filter.
- Which one should I use for GPP tournaments?
- SaberSim or Stokastic. Both are built around simulations and ownership modeling instead of single-point projections, which is what large-field tournaments reward. We don't have that.
- Does FantasySportsEdge require a credit card?
- No. Sign in with a free account and every lineup builder is open.
