Mariner

A native macOS browser for the Gemini protocol, built with SwiftUI.

Features

• Gemini browsing — fetches and renders text/gemini as styled gemtext; other text renders as plain text; images and binary files show a preview/download page.
• TOFU certificate trust — pins server certificates on first use and warns on mismatch, with per-host handling.
• Client identities — import PKCS#12 (.p12) client certificates, stored securely in the Keychain, for hosts that require them.
• Bookmarks & history — persistent bookmark sidebar and browsing history.
• Per-host settings — customize trust and display preferences per capsule.
• Find in page and adjustable text zoom (⌘+ / ⌘- / ⌘0).
• Natural macOS experience — real menus and keyboard shortcuts (Back/Forward ⌘[ / ⌘], Reload ⌘R, Home ⇧⌘H, Find ⌘F, Bookmark ⌘D, Save ⌘S).
