About NFT Rarity Ranker

Determining the rarity of NFTs in a collection is essential for collectors, traders, and creators. This tool analyzes your collection's metadata JSON to calculate trait frequencies and overall rarity scores using the statistical rarity method — the sum of 1/(trait frequency) for each trait. Lower scores mean rarer items. All processing happens in your browser.

Statistical Rarity Scoring

Uses the standard trait-based rarity formula: total score = sum of 1/(trait frequency %) for each trait. The lower the score, the rarer the NFT.

Top 10 Highlighted

The rarest items are visually highlighted with gold, silver, and bronze styling. Easily spot which NFTs are the most unique in your collection.

Trait Frequency Analysis

See every trait type broken down by value frequency — discover which combinations are common and which are exceptionally rare across your collection.

Collection Statistics

View aggregate stats: total items, unique trait types, rarest item, trait count distribution, and average rarity score for the whole collection.
