Maybe joomla? I personally do not use, however, friends have a good opinion.
There is no alternative CMS to Wordpress. There is Joomla, Drupal etc, but those differ from Wordpress.
OctoberCMS is definitely one of the best alternative to WordPress. It is as simple as WordPress and you can install extension to extend its functionality just like you do by installing plugins in WordPress.
Mmm... it depends ;-) IMHO nothing on the market right now comes close to Wordpress as CMS in term of service, security and choice, but you didn't specify your needs. As others have suggested, Joomla and Drupal are surely worth a try if those are the services you are looking for. If instead your question was just regarding a blogger platform to write your journal or to create your own blog, aside from Google's blogger of course, there is Medium, Ghost.org and Steemit (this one blockchain based), have a look, I'm sure you'll find something useful. If you needed something in particular, just follow up in this thread, of course!
After almost 1 year later I'd confirm as a former Drupal-user that " nothing comes close to Wordpress..." as the former post stated it correctly. I became a sworn Wordpress-user in the end.
After reading your recommendation about Drupal/Wordpress I'll give Wordpress a try.
At first I'll going to install Wordpress on xampp and play around with a few plugins.
After that I have to decide which system works best for me.
If its websites you want you could maybe try Concrete5? or maybe BuilderEngine?
Not sure about them though as i never got BuilderEngine to work, And Concrete5 Is too complex.
You can explain, why you don't like Wordpress? Because 31% sites on net was built by Wordpress.
It depends on your profession and development skills and the type of web site requested by the sponsor.
If you are a graphic designer then wordpress will be fine.
If you are a developer and require a basic site with little visitors traffic, then wordpress or joomla will be fine.
If you are an advanced developer and you have to create a portal with high visitor traffic, then Drupal is the right path.
Wordpress, Joomla and Drupal have different philosophy and different purpose, as technical characteristics that directly influence the performance of a server when the website faces high user traffic.
In performance the worst of all is Wordpress because its architectural design has problems with the execution of multiple threads and even though you are looking for a solution to the performance, you will not find it because it is a problem that its creators caused from the beginning.
To create true intranets or portals, Drupal is the best, also in its latest version improved performance, the architecture is new and according to what is expected to find in a solution a systems engineer responsible for the performance of web servers. In addition Drupal by design supports having multi-tenant sites, which is very useful to create workspaces in an intranet.
It really depends on what you are looking for. Every CMS that I know of and have used (WordPress, Joomla, Drupal, Expression Engine, Concrete5, DotNetNuke, Alfresco and many of the shopping carts which do have CMS capabilities such as Magento, ZenCart, etc) have more the ability to do far beyond what any one website can ever need. This may involve adding extensions or plugins to achieve these capabilities. However, at the end of the day, what you have is a website with a bloated admin panel that most users will never fully understand. I recently had a client tell me that she had tried WordPress and it was just too complex for her to figure out..
My point is simply this. You asked for a good alternative to WordPress. First, that does depend on what you are doing with a website. But, more importantly and more directly. There is none. The best CMS is a custom coded one. Reason being, using myself as an example, when I code a CMS for a client, I make sure that I understand their business today and where they hope to be in their business 10 years from now. That bit of knowledge enables me to provide a solution that enables them to do just what a CMS should do (Manage Content Simply) without feeling the frustration of being lost inside of an admin panel that to many end users looks like a space ship control.
