Not long ago, building a professional WordPress site meant relying on page builders like Elementor or Divi. They gave you the drag-and-drop design, prebuilt templates, and the visual control that the default WordPress editor simply could not offer.
But Gutenberg has grown up.
Today, the native block editor is powerful enough for most websites. And when you add a solid block plugin on top of it, you can build full pages, landing sections, and complete layouts without ever leaving the editor or touching a page builder.
This shift created an entire category of tools called Gutenberg block plugins. Two of the most talked-about options right now are bBlocks and Kadence Blocks.
Both extend the block editor. Both offer free versions. Both help you build a great-looking website without writing any code. But they serve slightly different priorities, and picking the wrong one for your project can cost you time, performance, and a lot of unnecessary frustration.
In this post, we compare bBlocks and Kadence Blocks across everything that matters: features, block libraries, performance, ease of use, pricing, and real-world use cases. By the end, you will know exactly which one fits your project.
Let us get into it.
What Are Gutenberg Block Plugins and Why Do You Need One?
Before we compare both plugins, it helps to understand what problem they actually solve.
WordPress ships with a basic set of core blocks. You get headings, paragraphs, images, lists, buttons, and a handful of others. That works fine for a simple post, but it falls short the moment you want to build something more structured.
Want to show your latest blog posts in a grid layout? Core blocks cannot do that. Want a testimonial carousel, a countdown timer, a styled FAQ accordion, or a tabbed content section? All of these need either a page builder or a dedicated block plugin.
That is exactly where Gutenberg block plugins come in. They extend the editor with new, purpose-built blocks that handle these common design patterns. Instead of switching to a separate visual editor, you stay inside the native Gutenberg interface and just have more blocks to work with.
The benefits over traditional page builders are real:
- Pages load faster because block plugins load fewer scripts
- The editing experience is more stable since you work directly inside WordPress
- Updates and maintenance stay simple
- You avoid the proprietary shortcode lock-in that older page builders create
Both bBlocks and Kadence Blocks answer this need well. But they each make different trade-offs, which is what this comparison is all about.
Read What to Look for When Choosing a Gutenberg Block Plugin.
Overview of bBlocks
bBlocks is a lightweight Gutenberg block plugin built by bPlugins. The idea behind it is straightforward: give WordPress users the blocks they actually need to build real websites, without bloating the editor or slowing down the frontend.
The plugin offers 50+ custom blocks and focuses on practical, versatile elements. These are not niche or experimental blocks. They are the blocks that appear on almost every website: post grids, sliders, tabs, accordions, testimonials, countdown timers, call-to-action sections, and image comparison blocks.
Key Highlights of bBlocks
Performance-first codebase. bBlocks loads only the CSS and JavaScript required by the blocks you actually use on a given page. You are not loading the entire plugin’s asset library on every page load. This directly benefits your page speed scores and Core Web Vitals results.
Clean, beginner-friendly interface. The settings panels are organized logically. You do not need to dig through nested menus to find a padding control or a color picker. Everything sits where you expect it to be.
Google Fonts and icon library support. You can apply any Google Font directly from the block’s typography settings. You also get access to Font Awesome and Bootstrap icons without installing a separate plugin.
Reusable patterns. You can group blocks into reusable patterns and apply them across multiple pages. This is a real time-saver on multi-page websites.
Works with any theme. bBlocks does not require a specific theme. It works with popular free and premium themes right out of the box.
Pro version with targeted upgrades. The Pro plan unlocks deeper controls for specific blocks instead of hiding entirely separate blocks behind a paywall. That means the free version is genuinely useful, not a stripped-down teaser.
Core Blocks in bBlocks
Here is a closer look at what the plugin includes:
- Post Grid – Display posts in grid, list, or ticker formats. Supports category filtering, custom image sizes, excerpt control, and reading time display.
- Slider – Content and image carousels with smooth transitions. Pro adds cube, coverflow, flip, and card transition effects.
- Accordion – Expandable content panels, great for FAQs and structured content sections.
- Tabs – Organize content into neat tabbed sections without crowding the page.
- Advanced Buttons – Styled buttons with icon support, tooltip options, and popup functionality. Popups support video, image, iframe, and document content types.
- Countdown – Urgency timers with post-expiration display, dismiss button, and prefix/suffix content areas.
- Testimonial – Customer review and social proof sections.
- CTA (Call to Action) – Conversion-focused blocks for landing pages and service pages.
- Image Comparison – Before-and-after image sliders with hover and auto-slide options.
- Lottie Player – Lightweight animated vector graphics for your pages.
- Charts – Simple data visualization blocks.
- Cards – Content card layouts for features, services, or team sections.
Overview of Kadence Blocks
Kadence Blocks is of the popular Gutenberg block plugins for several years. It is particularly well-regarded among WordPress designers and agencies for its layout flexibility and deep styling controls.
The plugin takes a design-first approach. Where bBlocks focuses on delivering the right blocks cleanly and quickly, Kadence focuses on giving you fine-grained control over how every element looks. Think about typography scaling at different screen sizes, column gap adjustments, and hover state animations.
Kadence has also added AI capabilities in recent updates, including inline text editing, tone adjustment, grammar correction, and smart keyword optimization directly within certain blocks.
Key Highlights of Kadence Blocks
Advanced layout system. The Row Layout block is one of the most capable column layout tools you will find in any free Gutenberg plugin. You get detailed control over column widths, padding, margins, backgrounds, and responsive behavior.
Per-device styling. Many Kadence blocks let you set different values for desktop, tablet, and mobile. This gives designers precise control over how pages look at every screen size.
Global color palette. You can define a site-wide color palette and apply it consistently across all blocks. Update the palette once, and it reflects everywhere automatically.
AI integration. Kadence AI brings text generation, rewriting, and content improvement tools directly into the block editor. Useful for teams that combine page building with content creation in the same workflow.
Large prebuilt template library. Kadence comes with more starter patterns and section layouts than bBlocks. This speeds up the early stages of building a new page.
Strong theme integration. If you use the Kadence theme, everything connects tightly, including global typography, the header builder, and color settings. The full Kadence ecosystem works well together.

Performance and Speed: A Closer Look
Page performance is not optional for any website in 2025. Google uses Core Web Vitals as a ranking signal. Visitors leave slow pages fast. And both of these directly affect real business results.
This section is one of the most important parts of any best Gutenberg block plugin comparison, so we want to be specific.
How bBlocks Handles Performance
bBlocks was built with a lightweight footprint from day one. The plugin loads only the scripts and styles required by the blocks used on each specific page. If a page has a Post Grid and an Accordion, only those two blocks’ assets load.
This approach keeps file sizes small, cuts render-blocking requests, and contributes to faster Time to First Byte, better Largest Contentful Paint scores, and stronger overall PageSpeed results.
The plugin avoids global stylesheets that load across every page, regardless of which blocks you use. Everything is scoped to individual blocks. For developers and site owners tracking performance closely, this makes bBlocks easy to predict and easy to optimize.
In practice, a page built with bBlocks will typically load faster than an equivalent page built with heavier tools.
How Kadence Blocks Handles Performance
Kadence Blocks is not a slow plugin. The team takes performance seriously and publishes its own data on asset sizes. Compared to heavy page builders like Elementor, Kadence is noticeably lighter.
But the more design features you use, the more assets are loaded. The Row Layout block with custom backgrounds, hover states, and responsive padding controls generates considerably more CSS than a simpler equivalent. Per-device typography, the global palette, and the AI integration all add to the total incrementally.
On a simple site, the performance gap between the two plugins is small. On a complex site with many blocks, advanced layouts, and detailed styling, bBlocks holds a more consistent advantage.
For sites where Google PageSpeed scores are a business priority, or where hosting resources are limited, bBlocks is the safer choice.

Ease of Use: Which One Feels More Natural?
bBlocks in Practice
Install bBlocks on a fresh WordPress site, and you can build something useful within minutes. The blocks appear in the editor’s block inserter just like any native WordPress block. Search for “Slider” or “Accordion”, and you find them immediately.
Each block’s settings panel follows a consistent structure: layout options first, styling controls next, advanced settings last. You do not need to read any documentation to figure out where things live.
For a small business owner building their own site, or a blogger adding more structure to content pages, this is a real advantage. You spend time building your site, not figuring out the tool.
The Pro controls follow the same logic. Even advanced features like post offset in the Post Grid block or custom popup content in the Button block are presented clearly and without unnecessary complexity.
Kadence Blocks in Practice
Kadence is well-designed, but it asks more from you upfront. The Row Layout block has multiple tabs covering columns, background, border, typography, and responsive controls. The Advanced Heading block has separate panels for font, color, shadow, spacing, and per-breakpoint sizing.
For someone coming from Elementor or Divi, this feels familiar and even comfortable. For someone brand new to visual WordPress editing, the depth of options takes time to get used to.
Kadence does have solid documentation and an active community. Once you understand how the system works, building with it becomes fast and predictable. The global palette feature especially saves time on larger multi-page projects.
But the ramp-up period is real. If you are building under time pressure or just want to get something live quickly, bBlocks removes that friction.
Pricing Comparison: What Do You Get for Free?
bBlocks Pricing
The free version of bBlocks on WordPress.org gives you access to 50+ blocks with genuinely useful functionality. This is not a watered-down version built to frustrate you into upgrading. It is a complete plugin that can power most websites without spending a cent.
The Pro version unlocks advanced controls for existing blocks rather than gating completely separate blocks behind a paywall. Here is what Pro adds:
- Custom pagination and post offset for the Post Grid block
- Advanced slider transitions (cube, coverflow, flip, card)
- Device visibility controls across multiple blocks
- Shortcode support for key blocks
- Extra prebuilt patterns
- Advanced popup content types in the Button block (video, audio, documents, iframe)
- Popup security with password protection and login requirements
- Image comparison auto-slide and interaction controls
- Dismiss button and post-expiration options for the Countdown block
The Pro pricing is accessible for individual site owners and small agencies. Most people who use bBlocks regularly will find the upgrade easy to justify.
Kadence Blocks Pricing
The free version of Kadence Blocks is strong and actively maintained. The core block library covers most basic to intermediate design needs without any cost.
The Pro version adds:
- Advanced Form block with full styling control
- Evergreen countdown campaigns
- More prebuilt starter templates
- Modal and popup blocks
- Additional animation options
- Priority support
Kadence also offers bundle plans that combine Kadence Blocks Pro with the Kadence theme, Kadence Cloud, and other tools in the StellarWP ecosystem. These bundles make sense if you are going all-in on Kadence. If you only need the blocks plugin, the standalone Pro plan is what matters.
On pure value, bBlocks Pro delivers significant upgrades at a competitive price, especially considering how much the free version already covers.
SEO and Accessibility: What to Know
Building a website means building for search engines and accessibility, not just for visitors.
bBlocks and SEO
bBlocks outputs clean, semantic HTML. Post Grid blocks use proper article elements. Heading blocks respect heading hierarchy. Buttons render as anchor tags. None of this is flashy, but clean markup matters for how search engines crawl and index your pages.
The performance advantage we covered earlier also has a direct SEO benefit. Faster pages score higher on Core Web Vitals, and Google’s algorithm weighs those signals in rankings.
Kadence Blocks and SEO
Kadence includes a dedicated Table of Contents block, which generates anchor links automatically and helps search engines understand page structure. This is a genuine content SEO advantage for long-form pages and guides.
Kadence AI’s keyword optimization tools add another layer of value for content-heavy sites where on-page SEO is a consistent priority.
Both plugins output generally clean HTML. But for content-focused websites where search visibility is a primary goal, Kadence has a slight edge with its built-in SEO-oriented features.
Theme Compatibility: Will It Work With What You Have?
This is a practical concern that does not come up in enough plugin comparisons.
bBlocks and Theme Compatibility
bBlocks works with any properly coded WordPress theme. Astra, GeneratePress, Neve, Blocksy, Kadence, custom themes, it does not matter. The plugin drops in and works without any special configuration. This makes it a safe and flexible choice for developers who manage multiple client sites across different themes.
Kadence Blocks and Theme Compatibility
Kadence Blocks works with any theme too, but it performs best alongside the Kadence theme. When you combine both, global typography, color palettes, and header settings sync automatically. If you are starting a new project and open to choosing a theme, this tight integration is worth factoring in.
If you are already using a different theme, Kadence Blocks still functions well. You just miss out on the deeper cross-plugin integration.
Real-World Use Cases
The fastest way to understand which plugin fits you is to think through the types of projects each one actually suits.
A freelance photographer building a portfolio site. They need a clean design, fast load times, image blocks, and a contact section. bBlocks handles all of this without adding any bloat. The image blocks, CTA, and card layouts cover the use case cleanly.
A marketing agency building a SaaS landing page. They need complex column layouts, animated count-up stats, a styled contact form, and precise responsive control. Kadence Blocks is the stronger fit. The Row Layout system, Count Up block, and Advanced Form in Pro cover all of these needs.
A food blogger adding structure to recipe content. They need a post grid for the homepage, an accordion for FAQs, tabs for recipe variations, and countdown blocks for limited-time giveaways. bBlocks handles all of this in the free version, with no setup complexity.
A WooCommerce store adding feature sections to product pages. They want testimonial blocks, a comparison section, and CTAs. bBlocks handles these cleanly. bBlocks is also faster to set up for this kind of straightforward layout.
A nonprofit building an event and donation page. They need countdown timers, a styled contact form, and clean icon-based layout sections. Kadence handles this better with its Advanced Form, Icon block, and flexible Row Layout system.
The pattern is consistent. Straightforward project with speed as a priority? bBlocks. Design-complex project requiring layout precision and advanced styling? Kadence earns its place.
Is bBlocks a Good Kadence Blocks Alternative?
This question comes up often, and it is worth answering directly.
Many people searching for a Kadence Blocks alternative are coming from a specific experience. They tried Kadence, found it heavier than expected, spent more time in settings panels than actually building, or ran a PageSpeed test and did not like the numbers.
bBlocks fits this need well. Here is why.
The block coverage is practical. Looking at what most small and medium websites actually use, bBlocks covers the essentials: post grids, sliders, testimonials, accordions, tabs, countdowns, CTAs, and buttons. That covers the needs of most sites without any unnecessary extras.
The performance improvement is real. Switching from Kadence to bBlocks on a mid-size site often produces measurably faster page loads, particularly on mobile. For clients or site owners who have received bad PageSpeed reports, this is a meaningful fix.
The learning curve is shorter. Teams that struggled to onboard junior editors or non-technical clients to Kadence typically find bBlocks requires far less training. The interface is simpler, and the settings are easier to navigate.
None of this is a knock on Kadence. It is a quality product that serves a specific audience very well. But for users who find it more than they need, bBlocks is a capable and much lighter place to land.
Tips for Getting the Most Out of bBlocks
If you decide to go with bBlocks, a few practical habits will help you get the most from it.
Enable only the blocks you need. bBlocks lets you control which blocks stay active. Turn off anything you do not use. It keeps the editor clean and reduces any overhead in the block inserter.
Use reusable patterns for repeated sections. If your site uses the same CTA, testimonial block, or sign-up section on multiple pages, save it as a reusable pattern. You build it once and reuse it everywhere, which keeps your design consistent and saves a lot of time.
Pair it with a lightweight theme. bBlocks performs best alongside a fast theme like Astra, GeneratePress, or Blocksy. Both the theme and the plugin pull in minimal assets, which gives you the strongest possible performance foundation.
Review the Pro features before deciding. The free version handles most needs, but spend 10 minutes reading through what Pro adds for the specific blocks you rely on most. If you use the Post Grid or Slider blocks heavily, the Pro controls are worth considering.
Run a PageSpeed test after you build. Use Google PageSpeed Insights or GTmetrix once your pages are done. bBlocks’ lightweight output should give you a strong starting score, and the test will point out any remaining optimizations to chase.
FAQs About bBlocks and Kadence Blocks
Can you use bBlocks and Kadence Blocks at the same time?
Technically yes! But we would not recommend it for most sites. Running two block plugins side by side increases editor clutter and loads more assets. Pick the one that fits your needs and stick with it.
Does bBlocks work with the Full Site Editor (FSE)?
bBlocks works within the Gutenberg block editor. Full Site Editor compatibility varies by block type and is something worth checking in the plugin’s documentation if FSE is a priority for your project.
Is bBlocks suitable for WooCommerce sites?
Yes. bBlocks works alongside WooCommerce without issues. The CTA, testimonial, accordion, and post grid blocks are all useful for product and category pages.
Does Kadence Blocks slow down the editor?
With a large number of blocks active, some users report slightly slower editor loading times. Kadence lets you disable individual blocks to reduce this, similar to bBlocks.
Which plugin has better support?
Both offer support through WordPress.org forums. Kadence Blocks Pro and bBlocks Pro each include priority support for paid users. Kadence has a larger community and more third-party tutorials available, given its longer track record.
Final Verdict: bBlocks vs Kadence Blocks
After going through both plugins in detail, the honest answer is that neither one is universally better. They are built around different priorities and serve different types of users.
Choose bBlocks if:
You are building a blog, portfolio, small business site, or landing page. You want lightweight Gutenberg blocks that load fast and do not require a learning curve. You care about Core Web Vitals and want a plugin that adds minimal overhead. You want a clean editing experience that non-technical users or clients can navigate without training. You want a free version that is genuinely complete, not one designed to push you toward upgrading.
Choose Kadence Blocks if:
You are a designer or agency building complex, design-heavy websites. You need advanced row layouts, per-device typography controls, animated count-up blocks, or a full form builder with styling control. You are already using the Kadence theme and want the tightest possible ecosystem integration. You want AI-assisted content editing inside the block editor. You are managing a larger site where a global color palette and a big template library will save you real time.
For most everyday WordPress users, bBlocks is the more practical starting point. It gives you the blocks you actually need, keeps your site fast, and gets out of your way so you can focus on building.
If you are looking for a reliable, lightweight Gutenberg blocks WordPress plugin that covers real-world use cases without the overhead, bBlocks deserves a serious look.
Both plugins are free to install. Download them from the WordPress plugin directory, try them on a staging site, and see which one fits how you actually like to build.
