About WonderCMS

Short explanation: WonderCMS is a free and simple tool for creating websites. It doesn't require any setup.

Long explanation: WonderCMS is a flat file CMS (Content Management System) built with PHP, jQuery, HTML and CSS, developed since 2008. To run WonderCMS, 5 files need to be uploaded to a hosting provider/server - it doesn't require any additional configuration.

All files can be moved, backed up and restored by simply copy/pasting a few files. Moving them to another host doesn't require any re-configuration.

WonderCMS doesn't require a traditional/relational database like MySQL. The flat file technology enables WonderCMS to save all data to a text file (flat file) called database.js (in JSON format).

Short history

Who, why

I (a guy called Robert) started this project as simple CMS for maintaining my websites in college. The reason for this creation was, simply put, me being tired of all the over-bloated solutions that included too many unneeded features and required initial configurations. My goal was to create something simple and possibly something that I would enjoy using for years to come.

After using it for a while and liking the simplicity of it, I thought to myself maybe this could be my gift to the internet or a way of saying thanks and giving back, as I've been amazed by the internet since my childhood years. I decided to share it with the world and pledged to maintain it for free and I've been doing so for the past 10 years.

WonderCMS was born in 2008, open sourced in 2010 and been a growing idea ever since.

A growing idea of small but functional pieces of code that enables establishing web projects quickly and efficiently. The mission is to keep it small, simple, secure and hassle free.

I've been also incredibly lucky to have awesome supporters and contributors along the way, as they've made this an EPIC journey. WonderCMS would not be the same without these individuals.

If you really like WonderCMS and would like me to dedicate full time to the project, consider supporting WonderCMS with a donation or by becoming a WonderCMS patron.

WonderCMS 5 file structure

    - index.php // WonderCMS core file, contains most of the functionality
    - database.js // default database, gets created the first time you visit your website
    - .htaccess // creates clean URL's, denies access to database.js, disables directory/file listing and disables server signature
    - [themes folder]
       - [default theme folder]
    	  - theme.php // default theme file
    	  - [css folder]
	     - style.css // default styles

NOTE: WonderCMS one click update feature rewrites index.php and htaccess. Any changes made to these files will be lost after each update.

Privacy, future, updates

WonderCMS is not interested in any user data. It's completely track-free, cookie-less and without any obligations since 2008. Check the short Privacy Policy.

One of the WonderCMS goals is to provide a "perfect" core and push as little updates as necessary. This provides WonderCMS users with a hassle free experience. When a new update is available, updating is easy with the built in one click update feature which can be also important for delivering critical security updates. Every update comes from the WonderCMS GitHub repository.

To keep this project within it's nature, which is sustainable and tiny, WonderCMS will support a maximum of 25 themes and 25 plugins. Once this limit is reached in each category, a simple voting system will be established. Users will be able to vote for their favorite plugins and themes to ensure they stay in the chosen "25" on a monthly basis.

The voting comes in handy in situations where users feel one of the 25 plugins or themes can be replaced by a better one with similar functionality, or when a plugin/theme is no longer actively maintained. This is a good way to ensure we have a small and quality set of themes/plugins. The "25 chosen ones" of each category will be easier to maintain and watch over by the whole WonderCMS community.

Features that won't be included in WonderCMS

WonderCMS is meant to be a truly simple and tiny environment. Here's a short list of features WonderCMS doesn't support.

  • WonderCMS doesn't support multiple users. There is only one administrator and one password.
  • WonderCMS doesn't have permissions or user roles as it supports only one user (with super powers).
  • WonderCMS will not include an "auto update" feature. In the unlikely event of the official WonderCMS GitHub account being compromised, hackers would be able to deploy updates to all sites simultaneously. These type of malicious attacks are currently halted with the built in one click updater. This minimizes possible damage as users are encouraged to review code changes before using the 1 click update.

What can WonderCMS be used for

Is WonderCMS better or worse than _____?

WonderCMS supports and encourages all open source software and doesn't see them as competition. Every user has different needs and it's easy to realize WonderCMS isn't a perfect solution for every situation. The purpose of WonderCMS is to provide a simple alternative to website creating.
