A native macOS email client built specifically for Gmail — the speed and system integration of Apple Mail, with the labels, filters, and search Gmail users actually rely on.
Mimestream is a Gmail client written from the ground up in Swift, not a web view in a wrapper. It talks directly to the Gmail API, so labels, categories, server-side filters, and search operators all work the way they do on the web — inside a fast, keyboard-friendly app that feels like it shipped with macOS.
Why it makes the list
It comes from an ex-Apple Mail engineer, and it shows: real AppKit views, proper notifications, system contacts and calendar integration, and a three-pane layout that stays quick on huge mailboxes. For anyone who has bounced between Apple Mail (fast, but bad at Gmail) and the Gmail website (correct, but not a Mac app), Mimestream is the missing option.
