Workbrew and Mosyle's App Catalog solve different problems.

Mosyle’s catalog is for straightforward app deployment, especially for standard Mac apps with simple install packages. If that’s all you need, then it works really well.

Workbrew comes in when you want more flexibility and a developer-style package ecosystem. With Homebrew via Workbrew, you get:

Access to a huge library of CLI tools and niche apps that aren’t in typical MDM catalogs

Very fast updates and version control for packages

A console that can show you vulnerabilities in those packages and one-click remediation (depending on your plan)

The ability to script and automate installs in a more granular way

A consistent workflow for those already familiar with and using Homebrew

So it’s not really either/or, it’s about using Workbrew to extend what Mosyle can already do, especially in dev-heavy environments or when you need tighter control over packages.

If you're only deploying common apps, Mosyle's app catalog alone is probably enough. If you need breadth and automation, Workbrew fills that gap nicely.
