## What it is
Hive is a lightweight, fast key-value NoSQL database written in pure Dart, designed for Flutter and Dart applications. It supports encryption, multi-isolate access, and runs on mobile, desktop, and browser platforms.

## Use cases
- store key-value data locally in a flutter app
- persist app settings and preferences in dart
- offline local database for mobile apps
- encrypted local storage for sensitive data
- fast lightweight nosql storage without native dependencies
- cache data across isolates in dart

## When to choose
- you need a fast, pure-Dart key-value store for Flutter or Dart
- you want simple local persistence with built-in encryption
- you need cross-platform storage including mobile, desktop, and web

## When to avoid
- you need complex relational queries or SQL joins
- you need a full document database with indexes and query language
- your project requires a server-side database

## Facets
- artifact type: library
- maturity: active
- function: database, caching, cryptography
- domain: databases, mobile-development, cross-platform, developer-tools
- platform: cross-platform, browser
- tags: key-value-store, nosql, flutter, local-storage, encryption, embedded-database, mobile, desktop
