What is Radar?

Radar is built on top of engine.io, the next-generation backend for socket.io. It uses Redis for backend storage, though the assumption is that this is only for storing currently active data.
Radar is a tool in the Realtime Backend / API category of a tech stack.
Radar is an open source tool with 210 GitHub stars and 36 GitHub forks. Here’s a link to Radar's open source repository on GitHub

Radar's Features

  • More than just pub/sub: a resource-based API for presence, messaging and push notifications via a Javascript client library
  • Written in Javascript/Node.js, and uses engine.io (the new, low-level complement to socket.io)
  • Backend to multiple front-facing servers
  • REST API for working with web apps that don't use Node (presently, rework in progress)
