## What it is
Esplora is a block explorer web interface for Bitcoin and Liquid, built as a single-page app with RxJS and Cycle.js on top of an electrs HTTP API. It lets users browse blocks, transactions, and addresses, and ships with a REST API for programmatic queries.

## Use cases
- look up a bitcoin transaction by txid
- explore bitcoin blocks and addresses in a browser
- self-host a block explorer for bitcoin or liquid
- query blockchain data via a REST API
- view liquid network assets and peg transactions
- check mempool and fee estimates

## When to choose
- you need a self-hosted explorer for Bitcoin, Testnet, or Liquid/Elements chains
- you want a fast public-facing blockchain explorer with a REST API
- you need multi-asset and confidential transaction support on Liquid

## When to avoid
- you need an explorer for chains other than Bitcoin or Elements-based networks
- you only need raw blockchain data without a web UI
- you want a full node wallet rather than an explorer
