How to create custom desktop widgets on Mac
Turn a feed, website, status check, price, or repeated AI task into a small desktop widget with Kepo.
The Mac widget gallery is useful, but it only shows widgets that supported apps already provide. If you want a widget for a specific RSS feed, website, status page, price, repository, or AI workflow, you need a custom widget path.
Kepo is built for that gap. It helps turn repeated checks and small workflows into desktop widgets you can keep in one panel.
If you are searching for how to add custom widgets on Mac or how to customize widgets on Mac, the key difference is whether you are changing an existing app widget or creating a new widget from your own source.
A custom desktop widget should start with one repeatable question: what do I keep checking, and what is the smallest view that answers it?

Quick solution guide

Try the workflow in Kepo
Create desktop widgets for the feeds, websites, monitors, and small checks you repeat every day.
Choose the source
Start with the source of truth. It might be an RSS feed, website page, GitHub repository, server endpoint, product ranking, market symbol, or text prompt.
The source matters because it determines what the widget can refresh and what information can be shown reliably.
Describe the widget in Kepo
Tell Kepo what to show, where the data comes from, and how often it should refresh. Keep the request specific and small.
Good requests include the source, fields, layout, refresh interval, and the action the widget should support when clicked.
Review the generated widget
After Kepo creates the widget, check whether it answers the original question without making you open the full website or app.
If the widget feels crowded, remove fields. If it feels vague, make the title, status, or next action clearer.
Use built-in widgets and custom widgets together
Use built-in Mac widgets for supported Apple and app information. Use Kepo for the sources and workflows that are personal, specific, or not available in the widget gallery.
This keeps your Mac desktop simple while giving custom information a dedicated place.
