GutenKit vs Spectra: The Head-to-Head Comparison

In this section, GutenKit and Spectra are compared across various parameters. It includes interface and UX, block library and modules, performance and web core vitals, advanced features such as FSE and dynamic content, and pricing.

You’ll also know which Gutenberg plugin wins for every parameter.

1. Interface & User Experience (UX)

Spectra keeps things very native. Its settings panel looks and feels just like the default WordPress sidebar, which makes for a zero-learning-curve experience.

GutenKit, however, introduces more advanced on-canvas controls. It feels more like a traditional page builder. It offers draggable container widths and inline editing that feels snappier for complex layouts.

GutenKit is the winner for this face-off because GutenKit is both beginner-friendly for simple and complex designs.

2. Block Library & Modules

GutenKit offers a higher quantity of blocks, particularly focusing on simple and complex UI elements. 

On the other hand, Spectra sticks to the essential blocks and modules. Like GutenKit, every block provided is rock-solid and serves a functional purpose, like SEO-friendly FAQs, etc.

GutenKit excels in the number of blocks, modules, and templates. Each block has advanced customization for a level-up look. 

3. Performance & Core Web Vitals

Both plugins are built with a “clean code” philosophy. They avoid heavy JavaScript that can make your website bloat. 

Spectra is legendary for its asset generation. It only loads the code for the specific blocks you use on a page. 

On the other hand, GutenKit uses the latest Block API Version 3, which keeps the editor fast even when building long and complex pages. Additionally, it is built with fast-loading assets. 

For this category, Spectra is the winner because of its lighter footprint compared to GutenKit. 

4. Advanced Features: Full Site Editing (FSE) & Dynamic Content

GutenKit is built for the dynamic web. It has Query Loop Builder and Dynamic Content features that wow every user. Although Spectra has a recent feature called Loop Builder, GutenKit still offers more “if/then” display conditions for content.

Spectra has a heavy workflow compared to GutenKit. In this comparison, it’s obvious that GutenKit is the winner because of its simplified FSE approach, and it gives an Elementor-level control within Gutenberg. 

5. Pricing and Free Plan Comparison

Both offer generous free versions on WordPress.org. The Pro versions unlock the truly “builder-level” features like the Popup builders and advanced Loop builders.

The data indicates that GutenKit is currently leading the market due to its extensive range of free features and cheaper pricing tiers. 

How to Choose the Best Gutenberg Page Builder 

To choose the best Gutenberg page builder, one must meet these requirements:

1. Know the goal of your website

Make sure that you know the goal of your website. You can ask yourself if you want to build a blog, a business website, a portfolio website, or an eCommerce store. Once you determine your niche, think if you just need a simple design or an advanced layout. 

2. Look for essential features

The best Gutenberg plugin should offer advanced blocks, impressive layout and design control, and prioritizes user’s comfort. You can examine the plugin you want to try to see if it has containers/columns, image galleries, sliders, advanced image accordions, etc. The number of features is not the only thing that matters. Assess if each block has good layout and design control. Don’t forget to put in your list how the plugin is to a user like you. If you don’t have that much experience in designing, is it user-friendly or not?

3. Check if it prioritizes performance and speed

Performance is the biggest factor when choosing a plugin. Look for a plugin that allows you to disable the blocks and modules when not in use. This would help your website load fast. Check if the plugin uses semantic HTML elements and avoid unnecessary wrapper divs. In this way, your website would have a faster rendering in the browser and have better SEO and accessibility.

Also, look for a plugin that has minimal inline styles and does not have heavy animations and scripts. This would improve core web vitals.

4. Look for compatibility and stability

A good plugin doesn’t break whenever there’s an update to WordPress. It should be stable so that everything still works well after an update. Also, one factor to consider is the plugin’s compatibility with WordPress themes and other plugins like WooCommerce and SEO. A good plugin doesn’t crash because of other plugins and doesn’t affect the performance of other plugins.

5. Check customization and flexibility

Choose a plugin that has global styles and offers reusable blocks to keep design consistency and help you create your website faster. If the plugin has global styles and reusable blocks, you can eliminate human error, and it becomes more professional. 

Additionally, make sure that the plugin offers dynamic content, especially if your niche is a blog website. It can automatically display data, such as posts, authors, and categories. 

6. Check the price and compare free vs. pro versions

Most of the plugins offer free and paid versions. So, do not always target a cheaper plugin. Compare it with other available options in the market. Some offer a cheaper paid version, but always look if it has all the blocks you need. Also, check if its free version has sufficient features to start a basic website, so you could try its performance. Note that you don’t have to pay too much if your goal is a basic website.

7.  Check the Support and Documentation

It’s not always a guarantee that your plugin functions all the time. Sometimes, there’s a minor technical error that might occur. So, look for a plugin that has dedicated and committed support. You can check the reviews on wordpress.org so you can evaluate what the reported technical issues are and how fast the support provides a resolution. 

Moreover, not all blocks and modules are easy to use, especially the advanced ones. So always check if there’s documentation you can use as a guide. 

Here’s a quick guide on what features to look for in special use cases:
