We have recently published a new tool that we are actively developing for the Cardano community. It is called ADAmarket.io and it is a free automated tool that analyzes nft metadata, trading data and calculates uniqueness and other properties.
We are running the site more or less in silent mode, as it still contains a lot of things that need to be fixed, finished or new features added, for which we are still collecting data day-by-day, but as an early beta, why not now.
We are officially planning to launch within two months. We will be glad for any feedback on our cardano cnft tool.
