Vieversys
Vieversys is a fast, elegant, and highly experimental macOS media browser built with Objective-C + AppKit. It provides a smooth three-pane experience for browsing local files and SMB network shares with rich thumbnail grids, instant previews, metadata inspection, slideshows, and side-by-side compare — all backed by a robust VFS layer and dual decode pipeline.
A deeply internal tool focused on performance, polish, and seamless local + remote media workflows.

Built for Power Users & Media Workflows
Vieversys combines native macOS ergonomics with serious media handling:
- Local + SMB VFS — seamless browsing of network shares with credential & bookmark support
- High-performance thumbnail browser — virtualized grid with fast filtering, sorting, and live refresh
- Rich preview pane — zoom, pan, rotate, mirror, fit/fill, and staged high-resolution loading
- Tabbed metadata inspector — Info, Metadata (EXIF/IPTC/XMP), and Technical (codec, duration, etc.)
- Slideshow & Compare — fullscreen timed playback and synchronized side-by-side viewing
- FFmpeg integration — direct library decode fallback with VideoToolbox hardware acceleration
Smart & Responsive Experience
- Progressive directory streaming with instant UI feedback
- Intelligent neighbor preloading around current selection
- Memory-pressure aware thumbnail and preview caches
- Keyboard-first navigation with extensive shortcuts
- Persistent bookmarks, recents, and window state
- Automatic local directory watching with debounced refresh
Everything feels native, fast, and predictable — even over SMB.
Technical Foundation
- Clean layered architecture (UI → Domain → Services → VFS → Decode)
- Dual decode path: Apple QuickLook first, FFmpeg fallback second
- Direct
libsmbclientintegration with custom FFmpeg IO for remote media - Persistent config and thumbnail cache under
~/.config/vieversys - Performance harness and hang diagnostics tooling for development
Current Status
Vieversys is a highly experimental and internal project. It is under active development as a personal media management tool and architectural playground. No public releases have been made.
It already delivers a smooth, responsive experience for both local and networked media libraries, with strong emphasis on preview quality, navigation speed, and macOS-native polish.
Vieversys is for users who want:
- a beautiful, fast native macOS media browser,
- seamless local + SMB network share support,
- rich preview and metadata tools,
- and deeply customizable experimental software.
Built as a highly experimental project to explore high-quality macOS media browsing architecture.
