Chartwell for Mac

Your charts.
Your Library.

A local-first Chartwell workspace for Apple silicon Macs. The app runs privately on your computer, while live data requests go to official providers.

First public release preparing

The download is not public yet.

The release is being prepared as a signed, notarized and stapled DMG. This page is the permanent download address and will point to the qualified installer when it is ready.

What the Mac app includes

Local workspace
Your Chartwell Library, backups, caches and logs live in your macOS user account—not inside the replaceable app.
Private runtime
Chartwell runs its own locked R and Python environments on a private loopback address. No repository, Homebrew or terminal is required.
Credentials
Provider credentials are stored in macOS Keychain and are never bundled into the application or written to the Library.
Exports
Build PNG, SVG, CSV and PowerPoint outputs locally using the same chart definitions and provenance as the web product.
Live data
The workspace is local-first rather than fully offline. Provider searches and current history still use the internet where the underlying source requires it.
First target
Apple silicon on macOS 13 or newer. Intel macOS and Windows are later, separately qualified releases.
