What is Simple Machines?

Simple Machines Forum, most of the time called SMF is a free software package that supports online communities.

It runs on the classical couple PHP/MySQL, and is supported by most web servers (as soon as they run PHP).

Review Updates:

Simple Machines has been developed to one goal : provide a forum with PHP/MySQL technologies. Some Joomla plugins have integrate it directly to this famous CMS.

Please also note that the Wordpress and Drupal bridges are not officially supported. Use it at your own risks.

The Facebook Connect integration is provided through a module, called SA Facebook Connect Integration.

About Caching system, Simple Machines de facto supports the following PHP caches:

  • APC
  • eAccelerator
  • Turck MMCache
  • Memcached
  • Zend Platform/Performance Suite (Not Zend Optimizer)

Those cache mechanisms are particularly useful on small size servers, that need an high source code optimization to counter-balance the slowness of the hardware.

Does Simple Machines 1.1 correctly follow (X)HTML and CSS norms?

Simple Machines Forum uses a XHTML 1.0 Transitional Doctype by default, and its HTML syntax is based on a table layout, that is not really useful for CSS theming.

The general interfaces contains a lot of images, which is a little bit difficult for quick and dirty theme modification (color scheme modification for example)

However, it is clean and sympathetic to use.

Unique Features

Key points and major differences that make Simple Machines 1.1 unique:

  • Upgrade process is really clean and powerful. Simply overwrite your SMF installation by the last upgrading package, and simply go to <your-website>/upgrade.php page to update your forum.
  • A really good updates, themes and plugins (called modifications) system. See How The Simple Machines Upgrade Process Works? for more information.
  • Many features

Final Words


Simple Machines Forum is one of the best forum software ever tested here, and it really deserves a good score.

Several years of intensive development and a really important community help this software to be a direct competitor of other most famous forum softwares like : PhpBB, vBulletin...

The integration to Joomla, Drupal and so on are a really plus for webmasters who would like to create a community around a CMS software.

The Modifications and Themes lists are simply huge and you will always find what you are looking for inside this. More over, the community worked hard to provide converters, that make the transition and the migration from an old forum software to SMF really easy and smooth. A really good way to increase the market share Wink

It's a must have in forum software world.

SMF Online Manual

Easy to install for a techie, but as a non-techie I found the installation instructions quite confusing. I got it to install mostly by trial and error.
Good support from the community though.


The Feature-List is very old

The Feature-List is very old and should be updated.

SMF has many of the features with status "unknown" or "no".
You should review it again and you'll see the difference.
Thread Icons, Sticky, Users List, Online List, Unread Topics, Captcha Protection, Guest posting are build-in features.

Export PM, Bookmarks are available as Plugins.

CMS / Blog integration is possible with Joomla, Mambo, Wordpress, Drupal and many others.


Feature list is really old,

The owner of this site should

The owner of this site should look again at SMF, SMF 2.0 doesnt use tables, but semantic coding also support more db types


SMF User for 2 years I've

SMF User for 2 years

I've been using SMF for almost 2 years and have had zero complaints with the software. This was after using phpBB for 15 months and having a complete database shutdown not allowing anyone to post messages. After struggling with phpBB for that amount of time, I tried SMF by converting the databases and found that SMF is leaps and bounds over phpBB for eas of use, modifications are easier to do (click and smile vs. manual edits all over the place). I'm now using a very nice theme combo, SimplePortal and a number of other mods for arcade and quizzes and a chat software add-in that is working well. This software is very easy to install, setup and maintain. I'm glad I spend less time keeping it running and more time enjoying the site.


Thanks SMF User for sharing

Thanks SMF User for sharing your informative perspective. It's clear that SMF is a superior forum product but I would have preferred an application that supports some blogging/content management features because I would also like to post documents and info for the membership - not just have them post questions and comments. It seems like you have added a few add-ins that are really working well. What's SimplePortal - is it a standard mod? If there was a way, I would be interested in seeing what you have done.

I am also taking a look at drupal which is very powerful but with a steep learning curve and I am absolutely no techie. Thanks a lot for the headsup about phpBB. I liked the simplicity of bbPress and integration with word prss but it lacks e-mail notification which I consider essential.

There are several bridges

There are several bridges available to integrate SMF with other systems. Official bridges are available for e107, Mambo, XOOPs and iGaming CMS. There are also some unofficial bridges to integrate SMF with other systems such as Wordpress and Drupal.

SimplePortal is a portal mod for SMF (one of several such mods). See for more details.

In reference to the other

In reference to the other comments here about features that SMF does have...

Keep in mind that the only version of SMF that can be truly evaluated for the purpose of a review are the 1.1.x versions. These are also the only versions that should be considered by a potential user of this software at this time.

The 2.0 version of SMF has been in beta since 2008... and can not be considered as a viable choice for a current live/production forum. This is not an opinion. It is the official statement of the SMF development/support team.

Sadly... despite being a potentially competitive (if not superior) product in almost every way, the absurdedly long (IMHO) period to develop a new, modern version of the software takes it out of the running as a viable choice for for the new forum user at this time.

During the several years SMF has taken to develop a new version, their primary competition have developed multiple new, modern and stable releases. The competitors have dedicated their resources to producing a new and better product... while SMF has split their resources between new development and updates to their outdated 1.1.x versions. The slower development cycle, combined with internal fracturing of the development team and disputes over copyrights, should be taken into consideration about how well this product will be supported and updated in the future.

Another issue to consider is a recent trend by developers of SMF add-on mods to charge money for full working versions of their products... or to require cash donations to have access to new updates of existing mods or themes. When the primary, core product is free, its actually a slap in the face to those who developed it when 3rd party mod developers attempt to profit from it. The old expression for that is... "Like flies around an elephant's butt!"

Bottom line: If you are looking for new forum software to use in 2011, then SMF may be worth waiting for. But if you need a modern forum product now, you should seriously have a longer look at the other products listed and reviewed here.


In SMF 2.0, support for

In SMF 2.0, support for multiple databases are introduced. This was implemented by the developers as a new layer of database functions along with a new security model that provides a fast and reliable method to work through database systems.
