This is Titan Reactor the WebGL renderer + plugin system. It consists of three primary parts in order to function:

  • Titan Reactor - main app that loads replays & maps and creates sessions for viewing. Can be served statically.
  • Cascbridge - an asset server that reads from your Starcraft install and serves it to Titan Reactor locally
  • UI Runtime - the part of the application the runs in the iframe for UI plugins. Can be served statically.
  • Plugins - the plugins that can be served statically.


  • A purchased copy of Starcraft Remastered.
