Kadence vs Blocksy: A Hosting Company's Suite or a Specialist's Theme

Twin demos, very different companies behind the checkout

Both themes are free on wordpress.org, both are configured in the Customizer, and both put a lot of their muscle in a companion plugin: Kadence in Kadence Blocks, Blocksy in Blocksy Companion. On a demo you are comparing two competent products. On an invoice you are comparing two business models, and the business model is what you live with in year three.

Kadence is now a product line of Liquid Web. The old kadencewp.com address redirects to Liquid Web's software pages, the wordpress.org author reads Nexcess, and the docs moved to docs.nexcess.com. In May 2026 the company folded SolidWP into Kadence Security, Iconic into Kadence Shop Kit and Restrict Content Pro into Kadence Memberships, then swapped its add-ons and bundles for three yearly tiers. The community forum was retired in favor of support tickets. If a Kadence site is already misbehaving, our Kadence repair desk starts there.

Blocksy belongs to CreativeThemes, which sells one theme and still sells it two ways: yearly or once. The free theme has 300,000+ active installs and a 100 out of 100 rating from 873 reviews. Version 2.1.58 shipped on October 2, 2026, the freshest release of any theme we track; Kadence's latest free release, 1.5.2, dates from July 24. Staff answer on the public wordpress.org forum, though they asked one user for a live URL and declined to diagnose a localhost install.

So the real question is not which theme is better. It is which kind of vendor you want to lean on. One sells a suite: theme, blocks, shop tools, memberships, a firewall and backups under one account. The other sells a theme and leaves the rest of your stack to you.

Fifteen rows of Kadence against Blocksy

Every cell comes from vendor pages, theme source files and support threads checked on October 6, 2026. Speed lines quote the vendors; we have not benchmarked either theme, and you should distrust anyone who quotes one score for a theme rather than for a page.

On the front end, most rows land close to a draw. The gaps open in licensing, ownership and the shop add-on, which is where the rest of this page spends its time. For the settings that shape page weight in each theme, read the Kadence speed guide and the Blocksy speed guide.

Where each theme parks its CSS, and why fonts flip the result

Both themes turn your Customizer choices into CSS, and both have opinions about where it goes. Kadence splits its static stylesheets by component, so header, content, footer and sidebar rules arrive as separate files, then adds the generated rules inline on its kadence-global stylesheet. Blocksy hands you the choice under Customizer, General Options, Performance: Dynamic CSS Output as a global.css file, which the vendor recommends, or inline. A file can sit in the browser cache between pages. Inline rules ride along with every HTML response.

Fonts tip the scales the other way. Kadence's free Performance panel serves Google Fonts from your own domain and can preload them. Blocksy keeps Local Google Fonts in Pro, so a free Blocksy site asks Google's servers for fonts on every visit unless you self-host them another way. Neither theme leans on jQuery for its own front end; in Kadence 1.5.2, only WooCommerce-related scripts declare it. Both start light. Your plugins, images and tracking tags will decide the score, which is why a side-by-side theme speed test on one of your real pages beats any demo.

Two header builders that disagree about tablets

Headers are where both themes earned their fans, and where a small detail decides real layouts. Kadence builds two separate headers, Desktop and Tablet/Mobile, each edited under Customizer > Header. Its CSS shows the desktop header from 1025px, so a tablet held sideways at 1024px gets the mobile layout. Blocksy gives you three rows with separate desktop and mobile arrangements, switches to its mobile header below 1000px and keeps a second breakpoint at 689.98px. Neither theme documents a setting to move those lines.

• What free buys. Blocksy's free builder includes Account, Button, Cart, HTML, Logo, both menus, Search, Socials and the off-canvas Trigger. Free Kadence gives you the Trigger, an Off Canvas area and Mobile Navigation with collapsible sub-menus.
• What paid adds. Kadence Theme Kit Pro brings Conditional Headers, 20 extra Header Addons and the Ultimate Menu with mega menus. Blocksy Pro adds conditional headers, duplicate elements such as a second menu, a Color Switch, Wishlist and the Advanced Menu.
• A block-built header. Kadence also offers Advanced Header and Navigation blocks, so the header can live in the block editor. Blocksy Pro reaches a similar place with a Header Content Block element.
• Recent breakage. On Kadence 1.5.1 one owner's off-canvas drawer opened with zero menu items despite menus being assigned. Blocksy 2.1.58 began stripping input elements from the header HTML element, which broke a custom search form.

For an ordinary header, either builder will do and you will not miss the other. For an unusual one, test the 1024px width before anything else. Our guides to Kadence mobile header problems and a Blocksy mobile menu that will not open cover the usual suspects.

Five years of licenses, for one site and for a client roster

This is where the two vendors part company. As of October 2026, Kadence sells three yearly tiers with a footnote: 'Plans are priced per site.' The pricing page does not say how many sites a tier covers, and the terms page still lists limits only for retired plan names. Blocksy sells three tiers with plain site counts, each yearly or as a one-time lifetime purchase.

Run the arithmetic for one brochure site, assuming list prices hold. Five years of Kadence Essentials comes to $495. Five years of Blocksy Personal is $345, or $199 paid once. For a store, five years of Kadence Pro is $1,495 against a single $299 for Blocksy Business. That gap overstates things a little: Kadence Pro also carries a firewall, two-factor login, memberships and daily backups with one-click restore, which a Blocksy site buys elsewhere or skips. Price those before you declare a winner.

Read the lapse clauses too. Kadence says its products keep working if you stop paying, minus updates, premium support and premium templates, and owners of grandfathered pre-May 2026 plans who lapse must buy a new tier to return. Kadence refunds within 30 days. Blocksy refunds within 14 days and publishes no renewal price for yearly plans, so ask first. The Kadence pricing breakdown and Blocksy pricing breakdown go line by line.

Shop Kit against Shop Extra for WooCommerce stores

Both free themes run WooCommerce. Kadence's Customizer offers single-product layouts (extra title area, normal, narrow, fullwidth or sidebar), toggles for product elements, a payment-icons row, catalog settings and a store notice. Blocksy's free version adds shop and product controls of its own, which its wordpress.org listing calls advanced WooCommerce support. The serious tools cost money on both sides, and they come from very different places.

Kadence Shop Kit is the former Iconic plugin family under a new badge: WooThumbs galleries, Flux multi-step checkout, attribute swatches, quick view, wishlist, bundled products, delivery slots and a product configurator. It comes with the Pro and Elite plans. Blocksy's Shop Extra, on Business and Agency, is narrower and lives inside the theme's own extension system: quick view, a floating add-to-cart bar, off-canvas filters and cart, a gallery thumbnail slider and a wishlist.

Both have stumbled in 2026. A Patchstack advisory flagged an SQL injection in Shop Kit 3.0.6 and earlier, and some legacy-license holders asking how to update were pointed to Liquid Web's software support. Blocksy 2.1.50 broke the single product layout for some stores, with the gallery overlapping and details pushed below, until owners rolled back. The detail is in Kadence with WooCommerce, Blocksy with WooCommerce and our Blocksy product page fix.

Which buyer each theme was built for

Neither column is a judgment on code quality. Both themes are carefully built. The split is about how much of your site you want one company to own. If neither column fits, the theme comparisons hub has other pairings, including Kadence vs GeneratePress, Astra vs Blocksy and Kadence vs Bricks for builders who want a visual canvas.

A verdict for six kinds of site

Our hesitation with Kadence is not the code. It is the paperwork: unstated site counts, renamed products and support complaints since the consolidation, including one owner who reported no reply to six tickets in six days. Our hesitation with Blocksy is the rhythm: a busy changelog means testing updates on staging before a live store meets them, as owners learned when a Blocksy update broke the site. Both risks shrink under a hosting and maintenance plan that tests every update first.

When the honest answer is neither theme

Kadence and Blocksy solve the same problem: making WordPress pleasant to lay out. If your problem is different, a nicer theme will not touch it. A site that builds hundreds of pages from data, quotes jobs, runs a client portal or gates content behind real business rules ends up as Kadence or Blocksy plus a dozen plugins, each updating on its own calendar. That is the point where a custom Next.js build deserves a quote.

Next.js prerenders pages at build time and serves them from a CDN, sends less JavaScript through React Server Components, and keeps routing, redirects and metadata in code that is tested before deploy. It costs more up front and needs a developer for structural change. Athena CMS, included with every site we build, keeps day-to-day editing plain: fields, a real preview, every version kept, with agents like Argus watching for broken links and failing forms.
