Show HN: Imagin Raw – A 9MB Open-Source Alternative to Adobe Bridge for Mac

Summary

A lightweight, native macOS application for browsing, culling, and organizing RAW photos - built as a more efficient alternative to Adobe Bridge for read/rate/organize workflows. An iOS companion app is in development, focused on a simple way to browse your library, cleanup, in field backup of your shots, and scouting. UI: SwiftUI (macOS 14.6+). AppKit/UIKit for the thumbnails list where SwiftUI performance was poor RAW decoding: LibRaw (C++), wrapped via Objective-C++ bridge. CoreImage also used for other formats and as a fallback Metadata: EXIF parsed directly from RAW/JPEG binary structures; XMP sidecars read/written for Lightroom/Bridge compatibility File system monitoring: FSEvents for real-time folder change detection Search: NSMetadataQuery (Spotlight) for indexed file/folder search Concurrency: A mix of Tasks and OperationQueue Multi-root folder browsing - add any number of folders from local disks, external drives, or SD cards; no import step, no managed library Real-time file system monitoring - new photos, deletions, and folder structure changes are detected and reflected immediately RAW format support - via LibRaw, covering a broad range of camera manufacturers and formats Rating and color labeling - written to XMP sidecars (RAW) or embedded directly without re-encoding (JPEG/HEIC), compatible with Adobe Bridge and Lightroom Rejection workflow - a session-scoped label (not persisted across folder changes) for marking photos to delete; batch-delete via right-click JPG/RAW pair deduplication - when a RAW+JPEG pair exists, only the RAW is shown in the browser Two grid layouts - compact grid (more room for preview) and large grid (more room for browsing) Spotlight-backed search - search across files and folder names using the macOS indexing engine SD card ingest - copy photos into date-based folder structures, with optional simultaneous backup to a second destination Duplicate/similar photo detection - Review mode for quickly resolving near-duplicate burst s...
