Background and Why Bunny Code

Being a software engineer, we learn continuously to enrich ourselves. However, there are no integrated resources where we could learn from other people's coding processes and edit our own project at the same time. Not to mention battle with each other.

Bunny Code was borned to cope with the problem. Bunny Code is dedicated to help users learn by replaying coding processes as if video clips and practice by launching live battles. With Bunny Code, users can edit codes, run codes, control versions, replay codes, launch battles whenever they want !

  • Preview coding archives of projects at the first time users go into the workspace.
  • Provide various shortcuts to help developers edit project much faster.
  • Allow user run codes immediately after they edit codes or watch codes.
  • Create version from latest coding process and provide version control. Help users compare differences between version by replaying projects' coding processes.

Features - Battle Valley

  • Choose a question level, launch a battle, then user can compete with others in battle valley.
  • Watch a live battle in battle valley as long as user want.
