The first platform to filter wash trading systematically and publish the adjusted numbers, still free to read.

Write the query yourself and see exactly how the number was produced — the only fully transparent option here.

The widest chain coverage in the category, free to use, with metrics that need reading carefully.

The strongest wallet-labelling dataset applied to NFTs, priced well above what a collector will want to pay.

Visualises wallet connections so concentrated ownership becomes obvious in a glance rather than a spreadsheet.

One thing, free, done accurately: what the floor was, and when.

The most complete collection-level analytics for Ethereum NFTs, with methodology notes most rivals skip.

Entity attribution applied to collections, with a free tier that outperforms several paid rivals.

Built specifically to find manipulation and counterfeit collections, which is the most useful thing an NFT tool can do.

Free rarity ranks for tens of thousands of collections, answering a question that matters much less than it used to.

Free stats attached to the largest listing venue, reported by a party with an interest in the numbers looking healthy.

Measures attention rather than assets — genuinely novel, and measuring something that can be manufactured.

A tidy portfolio view across wallets and chains, valuing illiquid assets with more precision than they can support.
Fast trend detection built for a market that has largely stopped trending.

Built to reveal rarity the instant a collection is revealed, for a mint meta that has largely disappeared.
Score = Σ (mark × weight), rounded to 0.1. A criterion with nothing published scores 0.
This category is full of products that present estimates as facts. A rarity rank, an AI price prediction and a wallet label are all outputs of a model somebody built, with assumptions you are usually not shown. Our rubric therefore weights data accuracy first and method transparency explicitly: a tool that explains how it reached a number is worth more than one that displays it with more decimal places.
Wash trading is the specific problem here. NFT volume has been systematically inflated by traders selling to themselves, and any platform that reports marketplace volume without filtering is publishing a number that is wrong in a known direction. We check whether filtering happens and whether it is documented.
Several tools in this list market machine-learning valuations or predictive scores. We do not score predictive accuracy, because no vendor publishes a verifiable track record and we will not launder marketing claims into ratings. We score what the model is transparent about, what data it consumes, and whether the output is presented with appropriate uncertainty.
Block explorers, marketplace APIs and public dashboards answer most questions in this category at no cost. A paid tool has to beat that baseline meaningfully, and several here do not.
