## What it is
Tinc is a peer-to-peer VPN daemon that creates encrypted private networks over the Internet with automatic full-mesh routing and NAT traversal. Nodes learn about each other automatically after initial connections, and traffic can be forwarded through intermediate nodes when direct connections are not possible.

## Use cases
- set up a mesh VPN between multiple servers
- connect remote offices into one virtual LAN
- bridge ethernet segments over the internet
- create a secure private network with NAT traversal
- run LAN-only games and apps over the internet
- self-host a VPN without configuring individual tunnels

## When to choose
- you want a self-hosted, full-mesh VPN that scales to many nodes
- you need automatic peer discovery and NAT traversal without a central server
- you want to bridge ethernet segments or run in switch/hub mode
- you need a mature daemon packaged in most Linux distributions

## When to avoid
- you want a simple client-server VPN with a polished GUI
- you need WireGuard-level performance and modern cryptography
- you require a stable 1.1 release - only 1.0.x is stable and 1.1 is still pre-release
- you need commercial support or extensive modern documentation

## Facets
