AI Analysis

●●SolidCozyNiche Gem

Syncs zoom across two clipped frames so your eyes don't lose the stereo lock.

Strengths

•Cursor-anchored zoom keeps the focal point aligned in both eyes simultaneously.
•Progressive Web App architecture allows full offline use after initial load.
•Tiny 32MB Docker footprint makes self-hosting trivial on low-end hardware.

Weaknesses

•Only supports parallel (defocus) viewing, excluding cross-eyed users entirely.
•Lacks image processing features like automatic cropping or alignment correction.

Post Description

I couldn't find a viewer for the side-by-side stereo photos I take on my phone that met my requirements. So I built one.

Features: - Stupidly simple. Just select the pair of photos and show them side by side. - Works offline - Mobile and desktop - Zoom and pan - FOSS. No paywalls. No ads.
