## What it is
Mempool is a fully-featured Bitcoin mempool visualizer, block explorer, and API service, running publicly at mempool.space. It can be self-hosted with one-click installs on Raspberry Pi full-node distros like Umbrel, Raspiblitz, and Start9, or deployed at scale with Docker.

## Use cases
- visualize the bitcoin mempool and transaction fee market
- self-host my own bitcoin block explorer
- look up bitcoin transactions and blocks privately
- estimate bitcoin transaction fees before sending
- run a sovereign bitcoin explorer on my full node
- query bitcoin blockchain data via an API

## When to choose
- you want a privacy-preserving, self-hosted alternative to mempool.space
- you run a Bitcoin full node on Umbrel, Raspiblitz, Start9, or similar and want one-click setup
- you need detailed mempool and fee-market visualization
- you want a production-grade explorer with an API

## When to avoid
- you need an explorer for chains other than Bitcoin
- you want a lightweight tool without running your own node or server
- you only need occasional block lookups and are fine using a public site
