And you’ll benefit from many goodies when using an open source site builder, like:

  • Cost-effectiveness
  • Flexibility and customizations
  • Community support and updates
  • Extensive collection of themes, plugins and integrations
  • Security and transparency
  • Freedom to choose any hosting provider

This post covers:

Understanding Website Builders

What is a Website Builder?

A website builder is a tool that allows individuals, businesses and organizations to create websites without the need for extensive coding or technical experience.

It typically equips you with a user-friendly, intuitive interface and predefined themes. Users can then customize these designs by adding custom content, images and branding elements to build a unique and professional-looking site.

In most cases, you benefit from the handy drag-and-drop functionality, which makes it easy to arrange and organize elements.

In general, a website builder is an efficient solution to establish an online presence quickly, with minimal investment in time and resources.

Types of Website Builders: Proprietary vs Open Source

When choosing a website builder, you have two options: 1) a proprietary website builder and 2) an open source website builder.

What are the main differences between the two?

  • A proprietary website builder is developed and owned by a specific company or organization. Unlike open source website builders, the source code of proprietary website builders is not freely available to the public. Users can access the builder through a subscription or licensing model and are often restricted to the features and functionalities. It may also come with vendor lock-in and the risk of dependency on the provider’s long-term sustainability.
  • Open source website builder is a freely available tool to the public. In other words, everyone can access and modify the source code. Users can use the builder to create websites with high customization and flexibility, as they can modify the code and add new features as needed. Plus, open source website builders often have active communities of developers and users who collaborate to improve and maintain the platform.

Factors to Consider When Choosing a Website Builder

Whoever wants to use a website builder wants a quick, easy solution to build a pro-level website. Thus, these are by far the two most important factors to consider.

But there are many other elements and features that the software you choose should have.

Code-free customization

Look for a website builder with a user-friendly interface, intuitive navigation and drag-and-drop functionality. This ensures you can easily create and manage your website without extensive technical knowledge.

Ready-to-use designs

Ensure that the website builder offers a variety of templates/themes and design options that can be easily adjusted and matched to your brand and requirements. These will save you a lot of time and energy!

Features and functionality

Assess the website builder’s built-in features and add-ons. Depending on your needs, you may require stuff like contact forms, galleries, popups, or social media. Make sure the builder supports the specific functionalities you require. (But you can usually install a (free) plugin to add the element you need.)


With a high percentage of internet users accessing websites on mobile devices, selecting a website builder that optimizes your site for mobile viewing is essential. A mobile-responsive website ensures a positive user experience across various devices.


The builder you opt for must create websites that offer epic performance and load fast. Just like responsiveness, performance also contributes to boosting user experience.

SEO capabilities

Check if the website builder supports essential SEO features, such as customizable meta tags, URL structures and XML sitemaps. A builder that facilitates good SEO practices will help your website rank higher in search engine results.

Blog and online store

Even if you don’t create a blog or start selling items online initially, knowing that the website builder you pick supports making both is beneficial. Always be prepared for expansion.


Regardless of the website type you want to establish, you will definitely publish some type of visual content on your website. Double-check that the website builder supports different content types (image, video, audio, etc.) and formats (PNG, JPEG, SVG, etc.). Plus, don’t forget about the embeds!

Free and open source

Remember, although an open source site builder may cost you nothing, you will still have expenses, like purchasing a domain name, hosting and even premium themes and plugins.

Data ownership

Ensure the website builder allows you to retain ownership of your website’s content and data. Avoid platforms that lock you in and make it challenging to migrate your site to another service in the future.

Considering these factors, you can select the website builder that best aligns with your needs and helps you create a successful and functional website.

Open Source Website Builders: A Deeper Dive

Customizability and Freedom in Open Source Website Builders

Customizations and (creative and tech) freedom are two key advantages of open source website builders.

Unlike proprietary alternatives, open source builders provide users unrestricted access to the source code for tailoring websites precisely to their needs.

The abundance of editable design elements allows users to create unique and visually appealing websites that align with their branding. Moreover, the freedom to modify the code grants unparalleled flexibility in adding or tweaking functionalities, ensuring sites are feature-rich and cater to specific requirements.

This level of customizability fosters innovation and empowers users to craft websites that stand out.

The Role of the Open Source Community in Development and Support

The community is crucial in developing and supporting open source projects, including website builders.

Volunteers, developers, designers and users collaborate to improve the software, add new features and fix bugs.

Their collective efforts result in continuous updates and enhancements, ensuring the website builder remains relevant and up-to-date with the latest technologies and trends.

The open source community also offers invaluable support through forums, documentation and online communities (like Facebook groups), where users can seek help, share knowledge and troubleshoot issues.

This collaborative approach fosters a sense of shared ownership, transparency and inclusivity, making open source projects more robust, secure and sustainable in the long term.

Security Considerations with Open Source Website Builders

Security considerations are crucial when using an open source website builder.

While these projects benefit from (regular) community examination, potential vulnerabilities can be exposed to a wider audience. Therefore, keeping the software and all its components up-to-date with the latest security patches and updates is essential.

Friendly tip: Regularly monitoring the project’s security announcements and participating in community discussions can help you stay informed about potential risks and best practices.

You should also ensure that any third-party plugins or extensions used in the website are from reputable sources and regularly maintained. Usually, inconveniences happen because of the extensions, not so much because of the poorly secured website builder/source code.

Remember, open source website builders generally offer a robust and secure foundation for building websites.

Cost Implications: Upfront vs Hidden

What about pricing?

As mentioned earlier, an open source website builder is generally free (with a few exceptions), eliminating the upfront costs. This makes open source builders an attractive option for budget-conscious individuals and businesses.

However, it is essential to consider “hidden” costs that may (and will) arise during the development and maintenance process.

These costs can include the need for technical expertise, customization and 3rd-party integrations. Additionally, hosting (and domain name), security measures and ongoing support are other expenses to consider.

While open source builders offer cost advantages at the outset, it is crucial to carefully assess the long-term expenses and make informed decisions.

Conclusion: Best Open Source Builders

Recap: Choosing the Right Open Source Website Builder

Ultimately, choosing the best website builder depends on your specific needs, technical expertise and the type of website you want to create.

Considering factors like ease of use, customization options, support and ready-to-use themes and extensions is essential when choosing the ideal tool.

Here’s a quick and final recap before you choose the right builder:

  • WordPress: Best for blogging, eCommerce, professional websites
  • Joomla: Best for corporate websites, online newspapers and small businesses
  • Drupal: Best for educational institutions, government websites and large enterprises
  • SilverStripe: Best for startups, SMEs and large enterprises
  • ConcreteCMS: Best for personal websites, blogs and eCommerce
  • ModX: Best for artistic and design-centric websites
  • Grav: Best for personal blogs, portfolio websites and small business sites

The Future of Open Source Website Building

As technology continues to evolve, open source website builders are likely to adapt and incorporate innovative features (hint: AI – have you seen the best AI website builders?) and functionalities driven by the collaborative efforts of the loyal community.

Customizability and flexibility will remain at the core of these platforms, empowering users to create unique and tailored websites to suit their specific needs.

Plus, the emphasis on security and transparency will continue to grow to ensure everyone gets the most out of the tool they use (with comfort and confidence).

As open source technology becomes more mainstream, we can expect increased adoption by businesses of all sizes, developers and individuals seeking cost-effective, reliable and cutting-edge solutions for their web presence.

In short, the future of open source website building looks very promising.


Is it possible to switch from one website builder to another?

Yes, it’s possible to switch from one website builder to another. Before switching platforms, backup your data and learn about the new builder’s process first (even talk to their support team), so the migration will go as smoothly as possible.

How does an open-source website builder differ from a paid one?

An open-source website builder and a paid one differ primarily in their accessibility, support and level of customization. While the former gives you complete (code and design) freedom, it might not come with the necessary support. Plus, an early-stage learning curve might be required. On the contrary, a paid site builder will provide you with all the resources required to create your website without being tech and design-savvy.

Can I build a professional website without coding knowledge?

Yes, using a website builder, you can build a professional website (blog, business, eCommerce, portfolio, etc.) easily and quickly without coding knowledge.

What is the learning curve like for these open source website builders?

One of the main learning curves of open source website builders is getting familiar with the platforms and gaining skills to navigate through them comfortably. But open-source website builders often provide user-friendly interfaces and documentation to facilitate the learning process. And many have active communities that offer support and guidance.

How safe is my data on open source website builders?

Your data is generally very safe when using an open source website builder, but keeping the software and all related components up to date is crucial. Additionally, employing strong access controls, using secure hosting services and regularly backing up your data are essential to enhance data protection.

Do open source website builders provide SEO-friendly features?

Yes, many open-source website builders offer SEO-friendly features to help improve your website’s search engine visibility. These features often include customizable meta tags, clean URLs, XML sitemaps generation and the ability to optimize page/post titles and descriptions. But they’re also usually compatible with 3rd-party SEO plugins and extensions, allowing users to enhance their website’s SEO performance further.
