Blocksy Theme Review: Why It's Our Go-To WordPress Theme

As a web development agency, we used to handcraft our themes from a custom boilerplate. That old-school workflow served us well for years. But with the introduction of the Gutenberg block editor and the rise of modern block-based themes, we decided it was time to evolve. Enter: Blocksy.

In fact, this website – prystine.co.uk – is built using Blocksy. 

It’s fast, flexible, plays beautifully with Gutenberg, and has quickly become our go-to recommendation for clients, freelancers, and fellow agencies looking for a seriously solid WordPress theme.

Here’s why it get’s a big thumbs up from us and why we’d recommend it to anyone looking to build a WordPress site be it a blog owner, freelancer or agency.

Why we love Blocksy (pros)

Just like when we were choosing a Gutenberg extension plugin (spoiler: we went with Stackable), we spent time researching and testing themes. GeneratePress and Kadence were solid contenders, but Blocksy came out on top after weighing up three key factors:

1. Speed & performance
2. Flexibility of design
3. Price

Let’s break those down:

1) Speed & performance

Speed matters. Whether you’re chasing SEO rankings or trying to reduce bounce rates, a snappy site is non-negotiable.

Blocksy is lightweight out of the box and doesn’t bloat your pages with unnecessary scripts or styles. It also includes some smart performance settings, like removing the legacy emoji script or lazy loading Gravatars, which helps you bolster your site’s speed even more.

Our own homepage, built with Blocksy + Stackable (and WP Rocket), scores very well in GTMetrix and Lighthouse without needing any extra optimisation.

2) Flexibility of design

Blocksy is a block-based theme done right. It offers deep design control straight from the WordPress’ customiser, with intuitive toggles and layout options that don’t make you feel like you’re fighting the theme.

It also comes with:

• A Header Builder and Footer Builder that’s incredibly easy to use
• Custom sidebars and layout options per post/page
• Global colour palettes and typography settings
• Support for modern design elements like sticky headers, transparent headers, and more

A range of theme options

Bonus: Starter Sites

If you want to skip the setup and go straight to building, Blocksy offers a great set of professionally designed starter sites. Whether you’re building a portfolio, an online shop, or a business site, you can start from a template and tweak it to your heart’s content.

3) Lots of options to improve WooCommerce

Blocksy Pro comes packed with a huge array of options and improvements for WooCommerce. From the intuitive product page layout builder to the advanced styling options for the gallery as well as a number of additional features.

You can enable a floating cart, wishlist, variation swatches, custom tabs and much more. In the past, these features would have required multiple plugins, bloating out your site and increasing the security risk.

4) Pricing & licensing

One of the big wins with Blocksy is the licensing model. While you can absolutely get a lot done with the free version, the Pro upgrade is affordable, great value for money and they offer a lifetime license.

Lifetime licences as an agency are great. We can deploy the software across client sites without worrying about renewing yet another yearly subscription or passing license costs on to clients.

What’s not so great (cons)

No tool is perfect. Here are a few minor drawbacks we’ve noticed:

• Header Builder is great, but not always intuitive for complex setups. Sometimes stacking multiple elements across devices can be fiddly.
• Learning curve if you’re used to older themes. If you’re coming from something like Divi or a classic theme, the customiser-heavy workflow might take a minute to adjust to.
• Some of the theme template options are a little bit limited. However, you can create a child theme or use additional CSS to get the desired look & feel.

That said, these are very minor gripes and honestly, nothing that’s been a dealbreaker for us or our clients.

Final Verdict

Blocksy nails the balance between modern design, performance, and usability. It’s powerful without being bloated, beginner-friendly without being basic, and flexible enough for full-scale agency projects.

If you’re building with Gutenberg (and you should be), Blocksy is hands down one of the best themes to build on in 2025 and beyond.
