About fizzy

fizzy is an open-source framework written in Zig for building editors and desktop or web apps. Its host app owns only a window, a frame loop, a layout and a document model. Features such as the file tree, tabs, text editing and image viewing are plugins registered against a versioned SDK. Pixel art and sprite animation come from the pixi plugin, which the site says is where fizzy started and is now a plugin in the store.

fizzy runs natively on macOS, Linux and Windows, and a web build compiled to WebAssembly runs in a browser without installation. Store plugins are fetched and installed on demand, and the site says a plugin built for a different SDK version is rejected when it loads instead of crashing. The project is pre-1.0 and described as moving fast, so its APIs and features may change. Pricing is not stated.

Key features

  • Pixel art and animation through the pixi plugin
  • Plugin-based design where built-in features are plugins using the public SDK
  • Native builds for macOS, Linux and Windows, including Apple Silicon and Intel
  • Image viewer for PNG, JPG, GIF, BMP and TGA with zoom and pan
  • Opens .zip archives as folders
  • Web build compiled to WebAssembly, with store plugins loaded on demand
Best for: Developers who want to build or customize editor-style tools in Zig, and pixel artists who want an open-source pixel art editor that can run on the desktop or in a browser.
Good for
  • Open source, with the source code available in a public GitHub repository
  • Built-in plugins are constructed the same way as third-party plugins, so they can serve as templates
  • The web build runs in a browser tab without installing anything
Watch out for
  • The project is pre-1.0 and described as moving fast, so features and interfaces may change
  • Plugins built for a different SDK version are turned away when loaded
  • Google Drive access is provided by a store plugin and depends on connecting that external service

fizzy FAQ

Can I write my own plugin?
Yes. The site describes a minimal plugin that registers itself and a sidebar surface in one function, and says you can copy the hello-plugin example, rename it, build it and turn it on in fizzy.
What happens if a plugin was built for a different version of the SDK?
Every plugin is checked against the app's shape when it loads. A plugin built for a different version is turned away rather than crashing the app.
Where are store plugins kept?
Store plugins live in their own repositories. When a release is tagged, CI builds it for each desktop target and the web, and fizzy installs and updates it in place.
Is something wrong or out of date?
