Simple, perfectly functioning multi-chain decentralized names/domains search aggregator. Displays which domain name extensions are or are not available. Most interestingly, it will also show for those which are unavailable at the time of, the date of expiration is shown so if you have persistent interest in procuring that specific name+extension combo, this will be insightful. Especially if you are trying to collect "sets" e.g. matching name for all the extensions e.g. .eth, .tez, .bnb, .hns, etc.
