Collection: Squarespace Plugins

The clever bit of this $39 plugin from SQSPThemes is where your testimonials live: in a blog. You create a blog collection specifically for testimonials, each one a post, and the plugin displays that collection as a rotating slider on any page of your site. That architecture means adding, editing or removing a testimonial is just editing a blog post, no code, no rebuilding sliders, and one central collection can feed sliders across multiple pages. It works on Squarespace 7.0 and 7.1 with any template, is fully responsive, and comes with a setup video, free email support, and the vendor's offer to help directly if you are not comfortable with files and code.

Squarespace background videos autoplay silently and loop forever, and visitors get no say in the matter. This $39 plugin from SQSPThemes hands control back, adding Play/Pause and Mute/Unmute buttons to your background videos. Everything about the buttons is customizable: colors, size and position, and you can hide either button if you only want one control. Beyond the design benefit, this is a genuine accessibility improvement, since motion that cannot be paused is a real problem for some visitors, and letting people opt into sound rather than forcing silence opens up what background video can actually do. It supports Squarespace 7.0 and 7.1 on all templates except Montauk.

The hover-to-see-the-second-image effect is standard on every major fashion and product retailer for a simple reason: it lets shoppers see the back, the detail or the lifestyle shot without leaving the browsing grid. Squarespace does not do it natively, and this $19 plugin from SQSPThemes adds it. The rollover works on product pages, in product blocks and in summary blocks, and supports both Squarespace 7.0 and 7.1. One honest limitation from the vendor: the plugin does not support Squarespace's focal point setting, so choose second images that frame well as-is. Installation is a zip with instructions, copy-and-paste as usual, with a Concierge Setup option at checkout and a Business License for client stores.

Yotpo's Reviews Widget is a strong review system, but wiring it into a Squarespace store the manual way means adding and configuring the widget on every single product, and keeping that up as your catalogue grows. This $29 plugin from SQSPThemes removes the chore entirely: it dynamically configures the Reviews Widget for each product in your store automatically. Add a product, and its review widget simply exists. It supports Squarespace 7.0 and 7.1 on all templates except Galapagos, and the vendor is precise about scope: the plugin adds the Reviews Widget only, not Yotpo's other components. You will need your own Yotpo account, and a setup video plus a Concierge Setup option cover the installation.

Embedded video players are heavy, and full-page video sections dominate layouts. This $29 plugin from SQSPThemes takes the cleaner route: any video link opens in a lightbox popup, triggered from Squarespace buttons or gallery items, so your page stays fast and tidy until someone actually chooses to watch. You can set the aspect ratio, open Video Blocks in the lightbox, and style everything through the vendor's CSS generator. It works on Squarespace 7.0 and 7.1 across all templates. Two honest notes before buying: videos will not autoplay on mobile devices (a platform restriction, not a flaw), and this plugin is video-only; if you want popups for forms, galleries or other content, the vendor's Lightbox Anything plugin is the broader tool.

Squarespace's built-in variant images are half a feature: the connection between what a shopper selects and what they see is looser than it should be. This $49 plugin from SQSPThemes tightens it in both directions: select a variant and the matching image displays; click an image and the matching variant gets selected. It also works inside Product Quick View, lets you choose which options trigger image changes (color yes, size no, for instance), and can group gallery thumbnails by the selected option so a customer viewing the blue version sees only the blue photos. It supports Squarespace 7.0 and 7.1 on all templates except Galapagos and Supply, and it pairs naturally with the vendor's Color Swatch plugin for a fully visual variant experience.

Squarespace pushes everything onto a new page: the form, the video, the team bio, the product details. Lightbox Anything keeps visitors where they are by opening any custom content in a popup, triggered from buttons, images, text links or galleries. You build the lightbox content with the same ease as a standard Squarespace page, so forms, videos, pricing tables, portfolios, signup forms and gated content are all fair game, and a built-in CSS generator matches colors, fonts, sizing and layout to your brand without code. It works on Squarespace 7.0 and 7.1 including Fluid Engine, can attach to buttons you already have, and support answers within 24 hours. $59, and its capabilities extend further with the Upsell, Promo, Gate and Tooltip add-ons.See what else made our roundup of the best Squarespace plugins in 2026.

Like the other Lightbox Anything add-ons, start with the essential fact: this is a $10 extension that requires the parent Squarespace Lightbox Anything plugin ($59) installed on your site. What it adds is a lightbox upsell for your product pages: once configured, it displays related products, services or upgrades in a popup, encouraging customers toward an additional purchase at exactly the moment they are already buying. Because it runs on the parent plugin's engine, the upsell is built from your own Squarespace content and styled with the same CSS generator, so it reads as part of your store rather than an intrusive ad. For most Squarespace stores this is the cheapest functioning upsell mechanism available.

Squarespace galleries give visitors very little to navigate with: arrows if you are lucky, and no sense of how far through the images they are. This $19 plugin from SQSPThemes adds the dot indicators you see on every polished carousel, to both gallery blocks and gallery sections (list and auto layout sections excepted). The dots are styled through a CSS generator, so matching your site's colors and sizing takes minutes rather than custom code, and it works across all Squarespace templates. Installation is straightforward with the vendor's instructions, support is responsive, and there is a Concierge Setup option at checkout if you want it installed and configured for you. A Business License covers designers using it across client sites.

The familiar rule for this vendor's add-ons applies here too: this is a $15 extension that requires the parent Squarespace Lightbox Anything plugin ($59) installed on your site, and it does nothing without it. What it adds is tooltips: attach one to any link on your site and a small window appears under that link carrying your explanatory content. It is the lightest-touch member of the add-on family, suited to defining jargon, clarifying pricing terms, adding context to navigation items, or explaining form labels without cluttering the page. Styling runs through the parent plugin's CSS generator, installation is the usual copy and paste, and support answers within 24 hours. Worth knowing before buying alone: the vendor's add-ons bundle includes this plus the Upsell, Promo and Gate add-ons for less than the cost of two individually.

The essential fact first: this is a $10 add-on that requires the parent Squarespace Lightbox Anything plugin ($59) installed on your site. What it adds is an age gate: a popup that asks visitors to confirm their age before accessing your site, which alcohol, tobacco, CBD and other age-restricted businesses typically need to show. Because it runs on the Lightbox Anything engine, the gate is built from your own Squarespace content and styled with the parent plugin's CSS generator, so it looks like part of your brand rather than a generic legal interstitial. At $10 it is the cheapest way we know of to add a presentable age gate to a Squarespace site.

"Only 3 left in stock" closes sales that silence loses. Squarespace tracks your inventory but never shows it to customers; this $19 plugin from SQSPThemes surfaces the live quantity remaining for whichever variant a shopper has selected. By default it runs on your product pages, and you can also enable it on the products page, in product blocks and in Product Quick View, so the scarcity signal follows customers wherever they browse. It works on both Squarespace 7.0 and 7.1, installs with copy-and-paste code, and honesty is the point: the number shown is your real inventory, not manufactured urgency, which is exactly why it converts.

This bundle packages all four add-ons for SQSPThemes' Lightbox Anything plugin: Upsell (product page upsells), Promo (promotional popups), Gate (age gates) and Tooltip. The non-negotiable requirement applies to the whole set: every add-on needs the parent Squarespace Lightbox Anything plugin ($59) installed on your site, and none of them functions without it. The value case is unusually clear: bought individually the four add-ons total $45, while the vendor prices the bundle below the cost of even two of them, so if you want more than one add-on, the bundle is the obvious buy. All four are built from your own Squarespace content and styled through the parent plugin's CSS generator, with the vendor's 24-hour support behind the lot.

Squarespace galleries always display images in the same fixed order, which means the photos at the bottom rarely get seen. This $19 plugin from SQSPThemes shuffles your gallery into a random order on every page load, so returning visitors see a fresh arrangement and every image gets its turn at the top. You can randomize every gallery on the site or only the blocks you choose, and there is an option to limit how many items show initially. It supports Squarespace 7.0 and 7.1 gallery blocks (gallery sections are not supported), and the vendor is clear about layout compatibility: grid, masonry and simple list galleries work fully, slideshows have limited support, and carousels are not recommended. Setup is copy-and-paste with a video walkthrough.

Squarespace shows product variants as plain text dropdowns, which forces shoppers to click through options one at a time to see what a product actually looks like. This SQSPThemes plugin replaces those dropdowns with visual swatches: hex color chips for solid colors, or small images for patterns and textures, so customers see every option at a glance the way they would on Shopify or Amazon. It supports both Squarespace 7.0 and 7.1, pairs neatly with variant images so choosing a swatch shows the right product photo, and the swatch styling is customizable to match your brand. $59, with a Business License available for designers building client stores. One honest limitation: swatches appear on product pages and product blocks, not on collection pages or summary blocks.For more ways to upgrade a Squarespace store, see our roundup of the best Squarespace plugins in 2026.

Squarespace can sell subscriptions natively, but the way it presents the subscription choice on product pages is plain to the point of undermining it: the option is easy to miss and the saving is easy to overlook. This $15 style upgrade from SQSPThemes fixes the presentation. It transforms the default subscription options into a cleaner, more professional layout and displays the discount clearly, so customers actually see the value of subscribing at the moment they choose. Setup needs no coding: install it and your subscription options automatically look better, with a demo available to preview the result. One scope note to be clear about: this styles Squarespace's built-in subscription feature, it does not add subscription selling to a store that lacks it, so your products need subscription options already configured.

Squarespace 7.1 removed something 7.0 users relied on: the sidebar. Blogs and content sites lost the standing column for navigation, recent posts and calls to action, and the platform never brought it back. This $59 plugin from SQSPThemes restores it, adding a fully customizable sidebar to any Squarespace template, featuring a dynamic menu, recent blog posts, and a Contact Us button to keep visitors moving toward the actions you care about. It follows the vendor's standard pattern: copy-and-paste installation with instructions, a Concierge Setup option at checkout if you would rather have it configured for you, and a Business License for designers rolling it out across client sites.

A small interface detail with outsized usefulness: this $19 plugin from SQSPThemes displays a subtle count of how many images a Squarespace gallery contains, so visitors know there are twenty photos worth exploring rather than assuming the first three are everything. The counter is deliberately understated, informing without overwhelming the page, and its styling runs through the vendor's CSS generator so the look matches your site without hand-written code. It is compatible with all Squarespace templates, installs with the vendor's usual copy-and-paste pattern, and pairs naturally with the same vendor's Gallery Dot Nav plugin if you want position indicators as well as a count.

Squarespace 7.1's native navigation stops at a simple dropdown, which gets cramped fast on sites with lots of categories or services. SQSPThemes' mega menu plugin takes the page-based approach: you build a normal Squarespace page containing whatever your menu should hold (multi-column links, images, text), and the plugin displays that page as a full mega menu in your navigation. You can customize the width, position and margins, and even make the menu sticky. Setup involves uploading the plugin files and pasting code, but the vendor is unusually hands-on about it: a setup video, responsive support, and a Concierge Setup option at checkout if you would rather not touch it at all. $59, Squarespace 7.1 only, with a Business License available for client work.See how it compares with the alternatives in our guide to the best Squarespace mega menu and navigation plugins.

Squarespace summary blocks can only display your own site's content, which leaves no clean way to surface an external publication, a news source or your content hosted elsewhere. This $49 plugin from SQSPThemes closes the gap: it displays any public RSS feed inside a genuine Squarespace summary block, styled and customized exactly like a regular one, so external content looks native to your site. The vendor has tested it with Medium, NewsBlur, Feedburner, Forbes, Wix and YouTube feeds (Vimeo does not work), and offers to add support for feeds it does not yet handle. One requirement: the feed must be public, not private or password-protected. It works on Squarespace 7.0 and 7.1 across all templates.

Long pages lose readers. This $59 plugin from SQSPThemes turns dense Squarespace content into accordion menus or tabbed sections, without coding, on both 7.0 and 7.1 and across all templates. It handles the classic uses (FAQs, service packages, pricing breakdowns, course modules) and a few less obvious ones, like adding the same tab set to every product page in one step. Multiple accordion or tab sets can run on a single page with independent settings, the layout automatically switches tabs to accordions on mobile, and a CSS generator handles the styling. Setup comes with clear instructions and detailed videos, and SQSPThemes' support is on standby if you get stuck.See what else made our roundup of the best Squarespace plugins in 2026.

First, the important part: this is a $10 add-on, not a standalone plugin. It extends SQSPThemes' Lightbox Anything plugin ($59), which must already be installed on your site for this add-on to work. What it adds is a promotional popup: sale announcements, launch offers or seasonal promos built from your own Squarespace content and styled through the parent plugin's CSS generator, so it looks like part of your site rather than a bolted-on marketing tool. There is a dedicated video tutorial for the setup, the vendor's support responds within 24 hours, and if you want the full set, a bundle combines the Promo, Upsell, Gate and Tooltip add-ons.

The reader who finishes your post and the shopper who views your product are both asking the same silent question: what else have you got? This $39 plugin from SQSPThemes answers it automatically. It detects the categories and tags of the current post or product and inserts a summary block of related items, with the current one sensibly hidden from its own recommendations. You control the presentation fully: every Summary Block customization option is available, plus a carousel design with autoplay, random ordering, a set count of items to display, and the choice to match by categories only or tags only. It supports Squarespace 7.0 and 7.1, each with its own setup video.See what else made our roundup of the best Squarespace plugins in 2026.

Squarespace has no native countdown timer, which leaves sales, launches and event pages with static text where the urgency should be. This $19 plugin from SQSPThemes adds a real-time countdown to any page, on both Squarespace 7.0 and 7.1, and the detail that makes it better than an embedded widget is what happens when the clock hits zero: you can hide the timer, open a lightbox, redirect to another page, replace it with text, or add text before or after it. That means an expired flash sale can automatically send visitors to the next offer instead of showing a dead timer. You can also run it on a fixed duration instead of an end date. Setup is copy-and-paste with a video walkthrough, and the styling is easy to match to your template.See what else made our roundup of the best Squarespace plugins in 2026.
