Zebar lets you create customizable and cross-platform desktop widgets.

⚙️ Installation

Downloads for Windows, MacOS, and Linux are available in the latest release.

For building locally, follow the instructions here.

🏁 Getting started

On first launch, Zebar generates some default widgets to %userprofile%/.glzr/zebar. This includes various examples and templates to get you started with creating your own widgets.

To create your own widget, a good way to start is by making a copy of one of the boilerplate configs created on first launch.

Widgets can be shared easily:

1. Zip your widget configuration.
2. Unzip it into the %userprofile%/.glzr/zebar directory.

🌟 Intro to Zebar

Widgets are powered by native webviews (similar to Electron, but more lightweight).

Each widget consists of:

1. A config file (with a .zebar.json extension).
2. An HTML file for markup and styling.

Any frontend framework can be used and boilerplates (e.g. for React, SolidJS) are included in the default widget configs.

Zebar exposes various system information (refered to as "providers") which can be used and displayed by your frontend. This includes stats like CPU usage, battery info, various window manager integrations, and lots more.

❓ FAQ

Q: Help! On Windows, Zebar is failing to start?

In some cases, updating to the latest Microsoft Webview2 version is needed (standalone download). Run the "Evergreen Standalone Installer" as adminstrator.

🧩 Providers

Through the zebar NPM package, Zebar exposes various system information via reactive "providers". Providers are a collection of functions and variables that can change over time.

• battery
• cpu
• date
• glazewm
• host
• ip
• keyboard
• komorebi
• memory
• network
• weather
