Nozo

Effortless Link Previewing for Modern Browsers

Preview links instantly without leaving your current context. Nozo provides a seamless, secure, and lightweight modal window for peeking at content via drag-and-drop interactions.

Overview

Nozo enhances your browsing workflow by allowing you to "peek" at links before navigating. Simply drag any link to the designated drop zone to open it in a non-intrusive modal overlay. Designed with security and performance in mind, Nozo ensures a safe and fluid experience.

Key Features

• Seamless Interaction: Drag and drop mechanic preventing accidental triggers.
• Security First: Automatically sanitizes URLs and blocks unsafe protocols like javascript:.
• Privacy Focused: Modifies necessary headers locally to allow standard framing without tracking or external servers.
• Lightweight: Minimal resource footprint with no background processes when idle.
