## What it is
Flysystem is a PHP file storage library that provides a single unified interface for interacting with many types of filesystems, both local and remote. It ships with adapters for local disks, FTP/SFTP, AWS S3, Google Cloud Storage, Azure Blob, WebDAV, and more, protecting applications from storage vendor lock-in.

## Use cases
- swap local file storage for S3 without rewriting code
- read and write files on FTP or SFTP servers through one API
- store uploads in Google Cloud Storage or Azure Blob Storage
- abstract file operations across multiple storage backends
- avoid vendor lock-in when choosing a cloud storage provider
- use in-memory or zip archive filesystems for testing

## When to choose
- you need a consistent filesystem API across local and cloud storage in PHP
- you want to switch storage providers without changing application code
- you're building a PHP application or framework that supports pluggable storage

## When to avoid
- you only ever target a single storage backend and want minimal dependencies
- you need streaming or performance-critical low-level filesystem access
- you're not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: file-system, object-storage, sdk
- domain: files, developer-tools, backend, cloud-computing
- platform: php
- tags: file-storage, abstraction-layer, adapters, vendor-lock-in, cloud-storage
