Bilup Documentation

Bilup is a Scratch modification built on TurboWarp. It keeps the Scratch editor you already know and adds a compiler that turns blocks into JavaScript, a large set of addons and themes, a project packager, a debugger, git version control, live collaboration, and a full community platform with accounts.

The editor and the community site ship from one build. You can use Bilup entirely in the browser at com.bilup.org, with no account and no install required. Sign in with a Bilup Accounts account when you want to publish projects, follow other people, and sync your settings across devices.

  • Introduction covers what Bilup is and who it is for.
  • Installation explains how to use Bilup on the web, as a desktop app, or through the packager.
  • Quick start walks you through building your first project.
