# Extension Store

> Browse, install, update and open Raycast extensions from the palette.

Enable extensions in **Settings → Extensions**, then run **Extension Store** from the launcher. The store shows Featured, Popular, Recently Updated, New and category shelves. Type to search the catalog.

## Inspect before installing

A row shows the extension's author, downloads and update information. The preview includes its description, commands, categories and a link to its store page. Read the commands and any required accounts before installing.

**Return** installs an available extension, updates one marked **Update**, or opens an installed one. Installation uses the same pipeline as Settings; you can still manage extensions there.

## Installed and Update badges

A Store installation records the source commit. **Update** means the catalog or Settings update check found a different version. A folder or GitHub installation without a known Store commit can show **Installed** without an update comparison.

Update is an extension update, not an application update. Redcast itself is [updated from source](/docs/reference/updates).

## Refresh and offline use

**⌘R → Refresh Store** reloads the catalog. A local cache can make reopening faster, and older cached results can appear while a refresh happens. A partial network response does not replace a complete cached catalog.

Browsing a cached listing does not mean the install bundle is available offline. Downloading or updating an extension still needs the relevant network access.

## Preferences and AI

Many extensions need their own preferences or OAuth login before commands work. [Installing extensions](/docs/extensions/installing) covers supported installation sources and package managers; [customizing](/docs/extensions/customising) covers commands and refresh behavior.

Extensions using `AI.ask` or `useAI` can use [your own model](/docs/extensions/ai) after you grant that extension access. Redcast does not provide a Raycast Pro account.

## Compatibility

The Store is a catalog, not a guarantee every command works. Redcast implements Raycast APIs inside JavaScriptCore and renders supported UI natively. Check [compatibility](/docs/extensions/compatibility) for gaps, and include the extension name and command in a bug report.
