mempool.space runs The Mempool Open Source Project, an open-source Bitcoin explorer that provides key data and visualizations of the mempool, blockchain, and layer-two networks like Lightning and Liquid. Users can track transactions in real-time, obtain suggested feerates, see critical mining stats, and much more. Anyone can easily host their own instance of the explorer at home with 1 click on full-node distros like Umbrel, RaspiBlitz, Start9, myNode, and RoninDojo.
