A/B and content ranking with compere

The problem

You have a set of creative variants and want a reliable ranking. Running an exhaustive pairwise survey wastes reviewer time on obvious matchups, and star-rating each variant in isolation gives inconsistent results.

How compere approaches it

1. Register each variant (headline, image, design) as an entity.
2. Show reviewers the UCB-selected pair and capture the click as a comparison.
3. Watch the Elo board converge; the winner emerges without an exhaustive survey.
4. Replay the comparison history any time — the ranking is auditable.

Where it fits (and where it doesn't)

compere fits when you want a self-hosted, transparent ranking from A-or-B judgements. It records verdicts you supply; it is not a traffic-splitting experimentation platform.
