The Best MLB Playoff Pool Software in 2026 (Ranked)

Commissioners who want the pool decided by series length as well as series winners.

• A game-count bonus set per round. Members pick the series winner and how many games it takes, and the bonus for getting both is configured round by round, which matters more in baseball than anywhere else, because a best-of-three and a best-of-seven deserve different weights. PoolsByRound offers series game-count picks too, and does not describe weighting that bonus per round.
• Free guest entries for the holdouts. The commissioner adds someone by name and types their picks, and the entry takes a seat like any other.
• Round-by-round picking with per-series locks. Members can pick each round off the real matchups, each series locking when its first game starts.
• Flat pricing at any size. $20 for the tournament, $90 for lifetime access to every tournament, free for one pool of up to 10 members with full scoring control and no ads.
• Pricing: Free is 1 pool, 10 members, 1 entry each. Tournament Pass is $20 for the MLB playoffs. Lifetime All-Access is $90 once.

Falls short: Brackets only: no confidence or squares pool for October. No native app. Every member needs an account; free guest entries cover the holdouts, but you type their picks. No entry-fee collection. And PoolsByRound is cheaper: it runs round-by-round pick'em pools free at any size.

First on a narrow claim: game-count scoring set per round, which suits a postseason where the first round is best-of-three and the last is best-of-seven. For a pool with no buy-in it beats RunYourPool on price at every size, $175 there at 100 entries against $20 here. If you want a non-bracket October pool, it has nothing for you.

Groups that already run their NFL and March pools in one place.

• MLB pools beside NFL, NBA, NHL, NCAA, golf and Oscars pools under one account.
• A private message board, which suits a month-long postseason.
• Automatic deadlines and real-time standings.
• Pick summaries and leaderboards under a commissioner hub.
• Free through the first week of the season.

Falls short: Pricing is per entry: $20.00 covers the first 10, then $2.00 each through 50, $1.50 through 200, $1.00 through 500 and $0.75 beyond, which is $100 at 50 entries, $175 at 100 and $325 at 200. The fee is waived when the pool collects its buy-in through Contest Vault, a LeagueSafe integration: Splash takes nothing, and each member pays a 3.5 or 4% processing fee on their own payment, $70 to $80 on a $2,000 pot. So a pool with a buy-in costs the commissioner nothing, and a pool without one pays per entry. Series-length scoring is not described publicly. It has an iOS app and no Android app.

The convenient established choice with the best message board here. The per-entry fee is the whole argument against it: $175 at 100 entries is more than a lifetime pass costs elsewhere.

Commissioners who want a free October pool with no member cap.

• "PAY WHAT YOU WANT to run your office pools with us. Yes, you can even choose FREE!", with no member limit attached.
• MLB beside the widest league list reviewed, the CFL, WNBA, PWHL and NLL included.
• Nine formats, so a group can run a bracket and a pick'em together.
• A Pool Wizard for setup, and autopicks for members who forget.
• Live scoring.

Falls short: Free pools carry ads. Paying reduces them in proportion, "Ad Removal Rate (%) = Payment / Removal Threshold x 100", and the threshold that clears them is computed per pool from format, features, participant count and duration, so an ad-free pool has no published price and costs more as the pool grows. Series-length scoring and commissioner manual entry are not described publicly. No native app is named.

The best uncapped free option for an MLB pool, as long as ads are acceptable; clearing them costs more as the pool grows. Playoff Pick'Ems is the better pick when the scoring model matters; OfficePoolJunkie is better when the member count does.

Commissioners who expect to correct entries during October.

• Baseball beside football, basketball, soccer, hockey and cricket.
• Commissioners can edit anyone's picks at any time, and set custom deadlines.
• Free pools with unlimited players, carrying banner ads.
• Downloadable user data.
• Private-label branding, custom email, and an "Install App" option.

Falls short: Free pools carry banner ads and score only nightly; "scores calculated within a few minutes of each game's end" is an upgrade. Upgrades are priced per player, and each of its 50-plus pool types has its own table, so budget from that pool's table. Private-label branding needs a template on top ($199.99 to $799.99). Series-length scoring is not described publicly. Open commissioner editing has no published audit trail.

Sensible when mid-postseason corrections are part of how your pool runs. Playoff Pick'Ems handles post-lock changes as one setting, off by default, with every change recorded.

Commissioners who want to build an MLB pool from a custom bracket template.

• A Custom Tournament Bracket that can be pointed at any competition, the MLB postseason included.
• The clearest published pricing here: free Standard, $10.00 per season Plus, Premium from a $20.00 minimum then $1.00 for the first 100 players, $0.75 for 101–400, $0.50 beyond.
• Player clones for commissioner-maintained entries: 1 free, 16 on Plus, 50 on Premium.
• Online entry-fee collection from Plus upward.
• A what-if simulator on paid tiers.

Falls short: No purpose-built MLB playoff pool is listed, so seeding, byes and mixed series lengths are the commissioner's problem. Ads on the free and $10 tiers.

The workaround, and the only platform here with both published prices and fee collection. You build the postseason from a blank custom bracket rather than picking it off a list, so the series game-count scoring that suits three different series lengths is not part of what you get.

Commissioners who want the widest sport list at no cost.

• Free, with no paid tier at all: "All features are free" and "No annoying ads".
• Both picking modes, its "signature feature": "Pick one round at a time or the whole bracket at the start".
• Deep scoring: head-to-head, beat the spread, underdog weighting, round significance, pick risk, parlays, over/under, and series game-count picks.
• "One Login, Multiple Picks (no-login players)": the commissioner adds a name and makes that person's picks, free, the same job our guest entries do. They can see the leaderboard but cannot pick.
• The broadest sport list of any free platform here: NFL, college football, NBA, WNBA, March Madness, the Stanley Cup and MLB playoffs, both World Cups, and Olympic events.
• A league message board, automatic deadlines, and leaderboards "updated within minutes after each game".

Falls short: Its World Cup group-stage pool is match pick'em, 10 points for a win and 4 for a draw, with the knockout run as a separate pool. There are no predicted group tables, so a predicted standing or a perfect group cannot be scored. No confidence or survivor formats, and no native app.

The honest free choice, and it beats Playoff Pick'Ems on price outright. Its no-login players are commissioner-run, the same as our guest entries. Its feature list stops short of group-stage tables and per-round weighting of the game-count bonus.
