Not all free open-source website builders offer the same functionality – some can bog you down with unnecessary complexity. What’s more, some of these platforms lack consistent support and make it hard to find compatible themes and plugins.
Ideally, you’d want to dive straight into creating your site without the hassle of endless setup and ongoing maintenance. So, to make your life easier, I’ve researched the best open-source website builders that help you save time while providing plenty of integrations, up-to-date documentation, and reliable support.
Alternatively, if you want to keep things simple, I also explored SaaS website builders like Wix that offer all-in-one solutions. These platforms take care of hosting, updates, and maintenance for you, while providing real-time previews, dedicated support, and automatic updates. They also offer free and affordable plans, allowing you to try them out risk-free or, at least, without breaking the bank.
Whether you’re a business owner who’s new to website creation or a tech enthusiast seeking an efficient solution, this guide will help you find the best platform to suit your needs.
Short on Time? These Are the Best Open-Source Website Builders in 2026
- WordPress.org – Beginner-friendly open-source platform with an easy drag-and-drop builder.
- Drupal – Best open-source builder for complex, multilingual, high-traffic sites.
- Joomla – Open-source CMS with extensive features for advanced e-commerce and large sites.
When Should You Use an Open-Source Website Builder?
I’m about as big of a fan of open-source software as they come, but it’s important to know when it is the right option for you. Open-source website builders are ideal if you need full control over your website’s resources, content, and design. But keep in mind that when I say full control, I mean full control. As in, it will be your job to oversee that each aspect of your site functions correctly.
Due to their nature, open-source builders are ideal if you have experience with server-side management, interpreted language coding, and you’re comfortable taking care of security features yourself.
However, if you can’t spend a lot of time on your site, or you aren’t a coding expert yet, open-source builders might be more trouble than they’re worth. If you are just looking for user-friendly options for your business or project, I’d recommend looking at a SaaS website builder instead.
What We Look For in the Best Open-Source Website Builders
When selecting the best open-source website builders, I focused on features and benefits that cater to open-source platforms’ unique advantages. Here’s what I prioritized during my tests:
- Customizability and flexibility. You need a platform that allows extensive customization to fit your specific needs. I chose website builders that offer a high degree of flexibility in design and functionality, so you can create a truly unique online presence.
- Active community support. An active community can be a game-changer for troubleshooting and innovation. I looked for platforms with strong community support, so you can access a wealth of knowledge and resources for any issues or enhancements.
- Regular updates and security. A lot of open-source software isn’t regularly updated to patch potential vulnerabilities. I made sure to prioritize builders that you can trust to keep your information safe.
- Comprehensive documentation. Clear and thorough documentation is essential for effectively using an open-source platform. All my recommendations provide detailed guides and tutorials, making it easier for you to navigate and utilize the platform’s capabilities.
- Optimization features. With open-source builders, you’ll be responsible for most of your site’s optimization. I made sure that the options on this list offered enough optimization features to keep your websites loading on time without you having to do the hard work.
1. WordPress.org: Most Beginner-Friendly Open-Source Builder
You know a platform is reliable when it powers over half of all the websites online. That is the case with WordPress.org. WordPress is an open-source content management system that gives you limitless control over your site while giving you a structured platform to organize regular content updates.
WordPress.org’s popularity also means that you have a lot of options to extend its functionality. There are thousands of proprietary and third-party templates for WordPress, as well as plugins for everything from calendar management to advanced e-commerce.
That said, while the WordPress CMS itself is free, you’ll have to manage your own hosting and domain name registration. Don’t worry though, modern hosting providers offer affordable and user-friendly options for managing WordPress sites, and some even include built-in optimization tools. If you’re interested in creating a site with WordPress, I recommend you take a look at our expert list of the best hosting providers in 2026.
Overall, if you’re aiming for a big, content-heavy site, WordPress has the resources to support your ambitions.
Features
- Easy monetization. You can put content behind a subscription, publish sponsored content, position ads and affiliate links on your site, create an online shop, and more without paying anything upfront, which isn’t the case with WordPress.com
- An abundance of DIY troubleshooting resources. WordPress.org has bustling community-based forums where thousands of experts hang out. Should you experience issues with your site, you can get free guidance there.
- 55,000+ plugins. Better SEO? Yoast SEO is here to help. Fight spam? Akismet can save you hours of manual work. Faster loading time? Take off with WP Rocket. There’s just one problem: too many plugins (or even one poorly coded) can cause too many problems. Some of them will have a beef with others. Be careful who you’re inviting to reside on your site.
2. Drupal: Most Secure CMS With Advanced Design Features
Drupal has a global community of over 1 million developers who contribute to its security through updates and code reviews, as well as a dedicated security team to address vulnerabilities. Drupal offers advanced customization if you are familiar with coding, though it might not be ideal for beginners.
Drupal is best suited to complex, traffic-heavy sites with large databases or resource libraries. It also offers built-in multi-language support for international sites. While it has fewer plugins and themes, it’s considered one of the most secure CMSs out there. Fun fact: NASA’s site runs on Drupal!
Features
- 50,000+ free modules. Need to supercharge your site with forms? Check out Webform. Protect your site from bots? Captcha is here to help. Create and edit page layouts with a click? Display Suite can save you valuable time. Evaluate how your content is performing? Google Analytics.
- 3,000+ free themes. You can customize any theme sans coding by altering the color palette, background, and favicon. Make sure you choose one that’s flexible, mobile-responsive, and covered by the Drupal security advisory policy. You can also purchase themes.
- Easy-to-use frontend and content creation tools. Creating and maintaining a Drupal site might require technical knowledge, but your site contributors don’t need to know any code. Writers and editors can add media, hyperlinks, and other elements using the simple editor. It’s as easy as using Word.
3. Joomla: Endless Resources for Complex Sites & E-commerce
Joomla’s scalability and Access Control List (ACL) system allow for detailed control over user roles – like assigning different access levels to customers and managers in an online shop. However, like Drupal, Joomla isn’t beginner-friendly. Personally, its content panel full of dev terminology, myriad of settings, and a complex database structure overwhelmed me. Even installing extensions is not as straightforward as on WordPress.org.
You can use the Joomlart Page Builder for drag-and-drop functionality. For anything more complex than a basic blog or small online shop, you either need technical knowledge or hire a Joomla developer. It’s best suited for complex e-commerce sites and medium to big sites that require advanced features.
Features
- Ability to use more than one template. Your Joomla pages don’t have to look alike! Joomla allows you to choose different templates for different pages and create diverse designs across your website. The customization options may vary based on the templates.
- 8,000 free and paid extensions. That’s far less than WordPress.org, but nothing to sneeze at. Joomla Content Editor (JCE), Widgetkit, Akeeba Backup, Admin Tools, RSform, and SP Page Builder are the most used among web developers.
- Advanced e-commerce functionality. It has a vast range of features that allow you to do almost anything with your store. Some of them include multilingual support, easy multi-store management, shopping cart and payment gateway integrations, control lists for different customer groups, one-page checkout, etc.
4. Symfony: Best For Complex Features & Easy Testing
Symfony is a full-stack, PHP, open-source framework that can be used to build all types of websites, from mommy blogs to the next Spotify. It boasts one of the most active communities among PHP frameworks, with users continuously introducing new and fine-tuning existing modules and other components.
Although it’s known for simplifying the web development process, you still need the technical know-how to rack up those benefits. If you have it, you can use Symfony to develop and implement complex off-the-shelf features for your site. Otherwise, get ready to pay for a developer or spare a few months to master the framework.
Features
- Easy testing. Symfony makes unit testing a breeze with its reliable tools for behavioral and functional unit testing designed to work with PHPUnit. It simulates HTTP requests and validates the output. You can also automate functional testing.
- Customization features. You can use the full stack version option if you need a complex website with multiple functionalities. The brick-by-brick process allows you to use specific features of the framework to develop a site with selective functions based on your unique needs, while the micro framework is ideal for developing very specific functionalities.
- 200+ independent components. These are standalone reusable PHP libraries that you can use as a foundation for various projects on your website to speed up the development process.
5. GrapesJS: Plenty of Customization Options
GrapeJS is a free, open-source web builder framework that helps you build HTML templates without touching a line of code. Personally, I didn’t find it as easy as it sounds – it takes time to master the platform if you’re a total beginner.
It has a drag-and-drop visual editor and blocks of reusable HTML, which are elements like buttons, forms, and images that you can use to build complex pages in less time. There are built-in blocks, but you can also create your own and give them different attributes, which ultimately requires you to code.
Features
- Responsive design. GrapesJS provides all the tools you need to optimize your site for different devices.
- Limitless styling options. Its Style Manager module allows you to customize website components separately for a unique look. You can use the default version or expand its capabilities using the Style Manager API.
- Layer and Asset Manager. The Layer Manager allows you to manage and move components faster, especially when your site has too many. The Asset Manager keeps your media files organized and helps you arrange them in ways that complement your site structure and aesthetic.
6. Publii: Best Open-Source Site Builder for Static Sites
Publii is an open-source static site generator. Unlike WordPress.org and Drupal, where content is stored and managed in a database, Publii uses a content source and creates HTML pages from components or templates that are uploaded directly to a server.
Publii has dozens of stylish themes, but only 13 of them are free options. Its plugin ecosystem is pretty basic, including essentials like Google Analytics, LiveChat, and Commento. There’s a selection of customization options and styling tools to personalize your site. Publii is mainly for creating blogs, portfolio websites, documentation sites, and landing pages, but don’t expect a static site to grow with you.
Features
- Content creation tools for bloggers. Publii offers 3 different, intuitive writing editors (block, WYSIWYG, and markdown editor), rich media options, Tags and Authors system to organize content with keywords, and more.
- Plenty of site speed tools. Static sites load faster, but Publii also provides tools like automatic file compression, lazy loading, responsive images, and code minifying to help you run even faster across the web space. You can also install the Image Decoding plugin for your image-rich posts to load faster.
- Strong SEO tools. Publii has all the basic SEO options plus automatic data markup, XML sitemap, and open-graph tag support. It also allows you to create your own SEO logic. The Pretty URL option is pretty cool – it allows you to switch to SEO-friendly URLs in an instant.
The Best Free Alternatives to Open-Source Website Builders
If you want to save time and money but still get a website completely tailored to your niche, I have listed some of the best SaaS website builders. These open-source website builder alternatives don’t require coding, and you can set them up in minutes.
Open-source website builders need you to be an expert coder if you’re going to achieve the same level of customization that Wix offers out of the box. Thanks to its collection of over 2500+ templates, user-friendly interface, and drag-and-drop editor, Wix gives you unlimited creative freedom.
SaaS website builders have a bad reputation for SEO and page loading speeds, but Wix overcomes this with advanced SEO and optimization tools. It even includes a step-by-step SEO checklist, so even if you don’t have experience designing websites, Wix can help your site appear on Google’s top page.
Wix’s free plan comes with access to all its customization tools, SSL certificates, managed hosting, and up to 500 MB of storage. If you need to connect a custom domain, remove Wix branding from your site, and scale up your resources, Wix’s premium plans start as low as $17.00 a month.
Wix is now only $17.00 per month!

WordPress.com is the self-hosted, SaaS version of the WordPress CMS. As you might expect, it takes care of all the technical aspects behind managing a WordPress site like hosting, domain registration, and optimization, while giving you access to the usual WordPress editor.
If you’re looking to create a blog for free, WordPress.com is an outstanding choice. The free plan comes with a limit of 13 GB of storage, which is plenty for most simple sites. Still, if you want to install any of the thousands of available plugins for WordPress, add storage space (and sites with lots of videos or HD images might eventually need), or connect to a custom domain, you will need to upgrade to a paid plan.
Paired with a page builder like Elementor or Divi, WordPress.com offers an incredible degree of customization and flexibility. Though it has a steeper learning curve than other builders, it’s ideal for complex, traffic-and-content heavy sites.
