## What it is
NyaaV2 is a self-hosted BitTorrent index and search website for anime torrents, built with Python/Flask and Elasticsearch. It is the source code behind the Nyaa torrent tracker, supporting MySQL/MariaDB-backed storage and multiple site flavors.

## Use cases
- host my own anime torrent tracker site
- self-host a bittorrent index with search
- run a nyaa-like torrent listing website
- search and browse anime torrent releases
- deploy a torrent site with elasticsearch full-text search

## When to choose
- you want to self-host a torrent index/search site for anime or similar media
- you need a Flask + Elasticsearch web application you can customize
- you want an open-source GPL tracker codebase to fork

## When to avoid
- you need a BitTorrent client rather than a torrent index website
- you want a turnkey product with no server administration
- you need Windows-first or SQLite-first support, which are weakly supported

## Facets
- artifact type: application
- maturity: maintenance
- function: search-engine, web-framework, http-server
- domain: web-development, files
- platform: python, self-hosted
