## What it is
Nano is a lightweight, high-performance game server framework written in Go. It provides a component-based networking architecture with built-in distributed system support for building real-time, social, and mobile game servers over TCP and WebSocket.

## Use cases
- build a multiplayer game server in Go
- create a real-time chat server with WebSocket
- implement a distributed game backend with message routing
- handle client sessions and push messages to players
- build a mobile game backend with TCP networking
- run asynchronous tasks like database lookups during login

## When to choose
- you are building real-time or multiplayer game servers in Go
- you want a lightweight alternative to heavier game server frameworks like Pomelo
- you need built-in distributed/cluster support for game backends
- you want component-based handler registration with session push/response semantics

## When to avoid
- you need a general-purpose web framework for REST APIs
- your game engine requires a full client-side or rendering solution
- you need a mature ecosystem with extensive third-party plugins
- you are not working in Go

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, websocket, http-server, rpc, serialization, networking
- domain: backend, microservices, web-development
- platform: go, windows, cross-platform
- tags: game-server, tcp-server, websocket-server, protobuf, real-time-games, lightweight, component-based, game-development, real-time, linux, macos
