PeekJS

PeekJS is a small developer tool: rich link previews without wiring a full metadata stack in every project. The API surface is intentionally tiny so it stays memorable and shippable.

• Drop-in script tag integration
• data-peek attribute convention for targeting anchors
• Lightweight popup layer that fetches Open Graph-style metadata and renders a calm preview card

The design constraint was zero config: no build step, no framework adapter required. That forced disciplined defaults: sensible z-index, focus behavior, and failure modes when a site blocks scraping.

A focused library that demonstrates how I like to ship utilities: narrow scope, crisp docs, and a live demo at peekjs.dev.
