Das ultimative Werkzeug für Paarvergleiche

Pairwise comparison (also called pairwise ranking) is a decision-making method where you rank a list of items by comparing them two at a time: “Which is more important, A or B?” Repeating this for a series of pairs produces a full ranking of the whole list — far easier than trying to order everything at once.

Comparing every item against every other takes n × (n − 1) ÷ 2 matchups — 45 comparisons for 10 items. PairwisePro’s quick mode uses an optimized merge-sort strategy that needs only around n × log₂(n) — about 25 comparisons for 10 items — with no loss in ranking quality.

They answer different questions. A weighted decision matrix scores each option against criteria you rate yourself — good when you know the criteria and can quantify them. Pairwise comparison forces direct between-option judgments, which reduces bias and works when criteria are hard to quantify. PairwisePro offers both tools for free.

Yes — it is one of the most common uses. Product managers paste their backlog or feature list, compare features head-to-head, and get a ranked priority order they can defend in planning meetings. You can also export the results to CSV for your roadmap.

PairwisePro is 100% free and requires no account. Everything runs in your browser — your lists and results never leave your device unless you choose to share a results link.
