## What it is
Tahoe-LAFS is a free and open-source decentralized storage system that distributes encrypted, erasure-coded file shares across multiple untrusted servers. It provides provider-independent security, so data remains confidential and intact even if some servers fail or are compromised.

## Use cases
- store files securely across untrusted servers
- set up a private decentralized cloud storage grid
- back up data with fault-tolerant redundancy
- share files with capability-based access control
- keep data private from storage providers
- run a self-hosted encrypted file store

## When to choose
- you need confidentiality and integrity guaranteed client-side, independent of server operators
- you want fault-tolerant storage with configurable redundancy across multiple machines
- you need capability-based secure file sharing
- you want a mature, audited open-source storage design

## When to avoid
- you need high-performance low-latency filesystem access
- you want a simple single-server NAS or cloud drive replacement
- you need rich ecosystem integrations or a polished GUI
- you require POSIX filesystem semantics or mounting as a native drive
