About
Mimestream is a real Mac app for Gmail rather than a web page in a wrapper. It speaks the Gmail API directly, so labels, filters, multiple accounts and search behave the way Gmail actually works, while the interface is built from AppKit and feels like Mail. It covers Google Workspace accounts, and a subscription funds development.
