Refbox is a floating reference app for creatives who want their inspiration visible while they work. Pin images, GIFs, videos & notes in always-on-top frames above your apps. No more window switching while you sketch, design, animate, or model.

Add media from the web, your computer, or your clipboard into a floating, resizable sidebar. View references in Masonry Mode (Pinterest-style), drag individual items onto your desktop that you can resize and rearrange, or use a full-screen Gallery for second monitors.

Add markdown-enabled notes for ideas, todos, or instructions without reaching for a separate app. Save clickable links as bookmarks to tutorials, articles, and other resources you need. Scrub through videos and GIFs with frame-by-frame playback. Create multiple collections of references and instantly swap between them.

Refbox is the essential companion for creatives who need inspiration at their fingertips while they work.

  • Need advice: Java Software Architecture for SaaS startup doing CRUD and REST APIs?
    Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find.
