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; what it does not describe is weighting that bonus per round, so a first-round call and a final can be worth different amounts.
• Byes handled in the bracket engine. The bracket carries the two seeds in each league that skip the Wild Card round straight into the Division Series, rather than requiring a custom template that fakes it.
• Round-by-round picking with per-series locks. Members can pick each round off the real matchups rather than filling the bracket before the Wild Card round, with 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 — 1 pool, 10 members, 1 entry each. Tournament Pass — $20 for the MLB playoffs. Lifetime All-Access — $90 once.

Falls short — Brackets only — no confidence or squares pool for October. No native app. Every member needs an account unless the commissioner keeps a guest entry for them — free, though commissioner-operated — where PoolsByRound lets participants pick for themselves with no account. No entry-fee collection. And it is not the cheapest option: PoolsByRound runs round-by-round pick'em pools free at any size.

First on a narrow claim — per-round game-count scoring and engine-level bye handling, which together fit baseball's uneven bracket better than a generic template does. It beats RunYourPool on price at every size — $175 there at 100 entries against $20 here — and beats OfficePoolStop's custom-bracket route on structure. 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 alongside 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, not per pool: $20.00 covers the first 10, then $2.00 each through 50, $1.50 through 200, $1.00 through 500 and $0.75 beyond — $100 at 50 entries, $175 at 100, $325 at 200. The only way out is a different commercial model: their help centre lists a contest's cost as "Contest vault or service fee for commissioner" — the vault routes entry money through the platform, which takes a cut of the prize pool instead. There is no free path: pay per entry, or give up a slice of the pot. Series-length scoring and bye handling are not described publicly. No mobile app named.

The convenient established choice with the best message board here. It publishes nothing about how a best-of-three or a first-round bye is handled, which is exactly where an MLB pool goes wrong.

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 covered alongside the widest league list reviewed, including the CFL, WNBA, PWHL and NLL.
• 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 entirely is computed per pool from format, features, participant count and duration, so an ad-free pool has no price published up front and costs more as the pool grows. Series-length scoring, bye handling and commissioner manual entry are not described publicly. No native app 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 covered alongside 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 every one of its 50-plus pool types is priced separately, so budget from that pool's own table rather than a headline figure. Private-label branding needs a template on top ($199.99 to $799.99). Series-length scoring and bye handling are not described publicly. Open commissioner editing has no published audit trail.

Sensible when mid-postseason corrections are genuinely 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, including the MLB postseason.
• 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. A generic custom bracket gives up the bye and series handling that make the MLB postseason awkward in the first place.

Commissioners who want the widest sport list at no cost.

• Free with no upsell — "All features are free", "No annoying ads", no paid tier at all.
• 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)" — no account needed.
• 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.
• Commissioners add players by name and make late picks for them, free — the same job our guest entries do.
• A league message board, automatic deadlines, and leaderboards "updated within minutes after each game".

Falls short — Its feature list stops at the group stage: no group tables, so a World Cup pool cannot score a predicted standing or a perfect group. No confidence or survivor formats, and no native app.

The honest free choice, and it beats Playoff Pick'Ems on price outright — nothing is cheaper than free, and its no-login players pick for themselves where our guest entries are commissioner-run. What its feature list does not reach is group-stage tables and per-round weighting of the game-count bonus.
