What Fizzy is

Fizzy is a free, open-source framework for building editors and polished apps from a host, SDK, and plugins. The host supplies the window, frame loop, layout, and document model; plugins registered with the SDK provide features. Included plugins cover a file workbench, text and code editing, Markdown preview, image viewing, and ZIP archive browsing. Store plugins can be installed and updated in place, including Google Drive and Pixi. The Google Drive plugin manages Drive files in desktop and web versions. The web build runs as WebAssembly and opens local files, ZIP folders, or Google Drive, while desktop builds support macOS, Windows, and Linux. Fizzy says files remain on the device or in Google Drive, with no accounts or server viewing them. It is pre-1.0, licensed GPL-3.0, and includes indexed color tools and sprite-sheet export to GIF, packed texture atlas, and .atlas JSON formats.

Who it suits

It suits developers and users building or extending editors across desktop and web platforms through plugins. It also fits people wanting local or Google Drive file access without accounts on a hosted server.

What it does well

  • Free and GPL-3.0 open source
  • Desktop and WebAssembly builds
  • Built-in editing and archive plugins
  • Plugins install and update in place
  • Local-file privacy model

What to know first

  • Pre-1.0 project
  • Third-party plugin policies vary
  • SDK version mismatches reject plugins
  • No tilemap tools

Verdict

Fizzy combines a host, versioned SDK, and plugin system for cross-platform editor applications. Its built-in tools, local-file approach, and plugin store are balanced by pre-1.0 status and version compatibility requirements.
