## What it is
geckos.io is a TypeScript library providing real-time client/server communication over UDP using WebRTC (SCTP data channels) with Node.js. It targets HTML5 real-time multiplayer games and chat apps with a socket.io-like API.

## Use cases
- build a real-time multiplayer browser game
- send low-latency unreliable messages between client and server
- add UDP-like communication to a Node.js game server
- create a real-time chat app over WebRTC
- replace websockets with faster UDP data channels

## When to choose
- you need low-latency, unreliable/unordered messaging for an HTML5 multiplayer game
- you want a socket.io-like API over WebRTC data channels
- you can configure UDP port forwarding on your server

## When to avoid
- you are new to multiplayer games and want abundant tutorials (use socket.io)
- you cannot set up UDP port forwarding or manage STUN/TURN servers
- you need simple reliable messaging where websockets suffice
