24 Essential Squarespace Plugins That Actually Work (2025)
Every year, we survey our newsletter subscribers and Facebook community to find out which plugins they’re using, loving, and recommending the most. This post is updated with their latest picks for 2025.
As one of the web’s longest-running Squarespace resources, we don’t just list plugins—we test them in real-world client projects, check for compatibility with the latest versions (7.1 and Fluid Engine), and prioritize speed, functionality, and ease of use.
Whether you're designing your first site or optimizing your hundredth, these are the tools serious Squarespace users swear by.

Lightbox Anything gives you total control over how and when your message appears—whether it’s an email opt-in, a limited-time promo, or a post-purchase upsell. With exit-intent, click, scroll, and timed triggers, this plugin helps you connect with visitors at the right moment.
Features: Mobile-friendly design, multiple trigger types, seamless integration with email platforms, and works with Squarespace 7.0, 7.1, and Fluid Engine.
Pricing: $59 (Business license available).
