How do widgets affect Shopify store performance?

Yes, many apps specialize in widget creation without the need for custom code. Tools like Shogun, PageFly, and Gempages let you build and insert widgets visually. Others, like Loox or Judge.me, focus on specific use cases like reviews or UGC. You can also use apps for sticky headers, cart drawers, exit-intent popups, and FAQ blocks. Most apps offer drag-and-drop interfaces and work across common themes. Look for those with strong reviews and fast load times. Always test new widgets in preview mode first to check for layout or performance issues.
