I'm creating a website. The web site was running using blogging platforms but it's being custom remodeled since the website will consist of 80% additional features.

Can there be anyway i'm able to obtain the publish benefits of wordpress without needing wordpress. or perhaps is there any library that may offer me the wordpress publish feature?

The functions are extremely complex and you'll need a very effective developer to export which include for your new Content management systems. But wordpress is free and you will do anything you want by using it however with the license limits.

You should keep to WordPress and modify your templates and functions.php when needed. 80% more features is simpler than the usual 100% new site. Best of luck to the developer attempting to prepare up an analog towards the core Wordpress features... its taken Wordpress ten years to obtain where it's!
