The biggest reason for WordPress’s popularity is its vast plugin ecosystem. If you need a new feature, there’s usually already a plugin to solve the problem.
This gives WordPress unmatched flexibility, but each plugin adds another component that must be installed, configured, updated, and maintained alongside the rest of the site.
WordPress: A massive plugin ecosystem
WordPress is open-source with a huge ecosystem of plugins. Solutions exist for everything from forms and SEO to e-commerce, memberships, bookings, analytics, and advanced integrations.
This means WordPress can be customized far beyond its core functionality.
When a feature is missing, you often find a plugin already built for that exact need.
Plugins range from free to paid, with some being simple and others complex systems that add substantial functionality to a website.
But each plugin adds another layer of responsibility
Flexibility comes with a responsibility.
When you install a plugin, it becomes another component that must work seamlessly with WordPress, the theme, and other plugins.
Plugins may need regular updates. Developers might change features or discontinue support. A future WordPress update could also require an older plugin to be updated for compatibility.
This doesn’t mean plugins are bad—quite the opposite. They’re a key reason WordPress is so flexible.
But the more plugins you add, the more you’ll need to manage.
SiteAdmin: Built-in features and a module system
SiteAdmin takes a different approach. Many features that would normally require separate plugins are already included in the platform.
This includes blogging, contact forms, media management, multilingual support, SEO tools, navigation menus, AI features, and parts of the website’s design and admin interface.
You don’t have to start by choosing a plugin for every basic function your website needs.
This creates a more cohesive platform where features are designed to work together.
SiteAdmin’s module system
SiteAdmin doesn’t just rely on always-active features. The platform also includes its own module system, allowing you to select which add-ons your website needs.
Under My Modules, you can turn modules on or off as needed.
This keeps your website simple at first and allows it to grow as new requirements arise.
Examples of standard modules include Blog, Contact Form, Cookie Consent, File Downloads, and Image Gallery.
Module Marketplace: Extend as you need
SiteAdmin also has its own module marketplace where you can find additional features.
As a customer, you can add modules directly from the marketplace. Once added, they activate under My Modules.
This means you don’t have to contact SiteAdmin every time you want to add a feature that’s already available in the marketplace.
Modules can be free or paid, depending on the feature’s complexity and scope. Prices are displayed before you add the module.
Free modules and advanced features
Many modules in SiteAdmin’s marketplace are free, with prices marked as Free – 0 SEK excl. VAT.
There are also larger features that may be split into separate modules, such as Booking and Shop, currently under development.
This way, SiteAdmin can grow from a simple business website to a more advanced solution without requiring a full platform upgrade.
Modules update automatically
A key difference from many WordPress plugins is how updates are handled.
SiteAdmin modules are managed as part of the SiteAdmin platform and updated centrally. You don’t have to manually check each module and start updates individually.
This also applies to modules added via the marketplace.
You choose what features you need—SiteAdmin handles the technical updates.
SiteAdmin controls the modules
Currently, SiteAdmin develops and manages its modules. This means the functionality and compatibility can be tested against the platform itself.
This differs from WordPress, where plugins can come from countless developers and companies.
The WordPress model offers a vast selection, but it also means quality, maintenance, and compatibility can vary widely between plugins.
SiteAdmin, in contrast, has greater control over which modules are available and how they integrate with the platform.
Need a feature that doesn’t exist yet?
The massive WordPress plugin ecosystem is a clear advantage. Someone is likely already building a solution for a very specific need.
SiteAdmin doesn’t have the same number of pre-made add-ons. Instead, new features and modules can be developed for the platform as needed.
SiteAdmin is expanding its module marketplace, and more features will be added over time.
For larger or more specialized needs, SiteAdmin can also develop custom solutions on request. This is another way to handle specialized features instead of searching for a plugin from an external developer.
Plugins make WordPress a powerful choice
It’s important to clarify that WordPress’s plugin model is indeed a significant strength.
The vast ecosystem makes WordPress highly flexible. You can combine plugins from different providers and build highly advanced solutions without having to develop all functionality yourself.
There are also many WordPress developers and agencies that can create custom plugins or adapt existing solutions.
For projects with very specific requirements, this freedom can be very valuable.
SiteAdmin prioritizes control over an open plugin ecosystem
SiteAdmin doesn’t aim to recreate WordPress’s massive plugin ecosystem.
Instead, the goal is to have the most common features built into the platform and additional features available through a controlled module system.
This gives SiteAdmin greater control over the platform and reduces the number of external components the customer must manage.
This is also a key part of SiteAdmin’s philosophy regarding updates and maintenance. The platform should evolve as a whole rather than each customer having to handle a long list of separate add-ons.
In the future, there’s also the possibility of letting partners develop custom modules via SiteAdmin’s API. After review and approval by SiteAdmin, such modules could become part of the marketplace. This is something we’re looking into if there’s interest.
WordPress or SiteAdmin?
| WordPress | SiteAdmin | |
|---|---|---|
| Extensibility | Massive plugin ecosystem | Built-in features and custom modules |
| External add-ons | Commonly used | No—features are built-in or added as SiteAdmin modules |
| Customization options | Very high | More controlled |
| Module/plugin marketplace | Very large selection | SiteAdmin’s own marketplace |
| Updates | Plugins updated separately | Managed centrally |
| Compatibility | Depends on chosen plugins, theme, and versions | Modules developed for SiteAdmin |
| Free add-ons | Very large selection | Several free modules available |
| Paid add-ons | Commonly available | Some larger modules may cost extra |
| Custom development | Custom plugins or external developers | Can be developed by SiteAdmin on request |
| Technical responsibility | Multiple components may require separate maintenance | SiteAdmin handles platform and modules centrally |
Two different ways to build a website
WordPress and SiteAdmin take two different approaches to building a website.
WordPress gives you a base platform and a massive ecosystem where you choose which plugins to use. This offers maximum freedom and allows the platform to adapt to nearly any need.
SiteAdmin, on the other hand, embeds more features directly into the platform and uses its own module system for features that don’t need to be on every site.
This means less freedom to choose from thousands of plugins—but also fewer external components you have to install, update, and manage yourself.
WordPress gives you a massive ecosystem to build with. SiteAdmin gives you a more cohesive platform where more features are already part of the system.
