# Esplora ### [Esplora - The Code Behind Blockstream Explorer](https://blog.blockstream.com/en-esplora-source-announcement/) Links: [[Blockstream]] - GitHub: [Blockstream/esplora](https://github.com/blockstream/esplora) (Typescript) Following the great reception we’ve been getting for Blockstream Explorer ([released in November](https://blog.blockstream.com/en-explorer-launch/)), today we’re releasing Esplora: the [free and open source software](http://github.com/blockstream/esplora) that powers the site. The software has been made available so that developers can contribute to the project, build their own extensions, or even create their own independent blockchain explorers. Esplora is based on a number of open source components. Using a modified [Electrs](https://github.com/romanz/electrs), a Rust implementation of Electrum Server written by Roman Zeyde, Esplora indexes blockchain data quickly from [Bitcoin Core](https://bitcoincore.org/) and [Liquid full node software](https://blockstream.com/2018/11/06/liquid-full-node-and-wallet-release/). Esplora supports the following features: - Bitcoin Mainnet, Testnet, and Liquid - [Bech32](https://blockstream.info/tx/c569c957fa2ea10c2342c3ab7fc9d4fd5fbe5898e4b6c37ec832cd7388b95380) addresses - [Confidential addresses](https://blockstream.info/liquid/tx/bc615100d80e55b1167d907d3ce2e5480f942b7c220ec1d62c71f175a36feaa1) (Liquid) - Links [peg-in](https://blockstream.info/liquid/tx/09b5179b2e8b8f0e15e47bf07a35aa50bf8792bfa7ec415a3362b42864dd7a44) and [peg-outs](https://blockstream.info/liquid/tx/ee89b9c9ce9573618d6d82c7c03ce241ee1199f76f5e30c8663d05c5c7c7cd45) between Bitcoin and Liquid - Light-Mode for reduced resource usage/personal use Our modifications to Electrs include Liquid support thanks to [rust-elements](https://github.com/ElementsProject/rust-elements), a Rust library for Elements written by Blockstream’s Director of Research, Andrew Poelstra. Other modifications include the addition of a Rust embedded HTTP server called [hyper](https://github.com/hyperium/hyper). Finally, the Esplora front-end is served to users by [nginx](https://www.nginx.com/).
