I don't like it overall aside from its privacy-related features. It's slow as you said, there is no clickable link for seeing transaction id, shareable link for txid and address and other features that can be seen in other blockchain explorers, it just shows recent transaction at least in mobile browsers, didn't check in desktop yet.
This is still in early testing development, they announced it will be improved in future with more features, and you can make suggestions for free access.
I don't need super-fast blockchain explorer with all the bells and whistles that can record and report connection between all my wallet and IP addresses.
SpiralBTC is a good mobile alternative for watch only wallet.
Cool project though, I'll definitely stick to Blockstream.info + Tor for now.
mempool.space + Tor and your own node is much much better than Blockstream in every way.
Comparing this with new thing like SpiralBTC is not realistic.
At current stage, i prefer self-hosted block explorer or block explorer with .onion address. But after they add more feature, i'll consider this website seriously.
Sure, but if you are not self-hosting btc node and just using Tor, I think that SpiralBTC is better option for privacy.
