Safety

KoBar asks before it installs

Plugins are code that runs inside KoBar with full access to the app. They are not sandboxed, so install only plugins you trust.

  • Installing, updating and removing a plugin always asks for your confirmation.
  • A plugin installed from a file or a GitHub link outside the official registry is marked as unverified before you confirm.
  • Replacing an installed plugin with a ZIP asks a second time, and installing an older version is refused.
  • A plugin that needs a newer KoBar is refused before anything is written.

For developers

Build your own plugin

Plugins are plain JavaScript. KoBar gives them React, the app’s state, a bridge to the main process and a way to add buttons, panels and settings.

Read the plugin developer guideOpen the plugin registry

List your plugin in Discover

  1. 1Add a manifest.json to the root of your repository.
  2. 2Publish a GitHub Release with the plugin’s .zip.
  3. 3Open a pull request that adds Username/RepositoryName to plugins.json in the registry.

Being listed in the registry is not a security review.
