Advantages & limitations of Custom CMS System - 

The Pros

Custom CMS Is for You

Open source is for everyone. They are standardized web-based applications. But, on the other hand, custom CMS is only built for you. They are designed in a specific way to fulfill your requirements. In short, you get precisely what you want.

Better Security

As open-source CMS codes are widely available, hackers and spammers are already familiar with the structure of the software. But on the other hand, custom CMS codes won’t be published; therefore, the chance of discovering security flaws is less. 

Better Customer Support

As you built the system from a hired web development company, you are guaranteed to have customer support if you need any help regarding CMS issues. You won’t have to rely on community support or a rigorous research process to find the solutions. 

Initial Cost Saving

You can reduce the cost by taking pre-built custom CMS.

The Cons

  • If you want to build a custom CMS from scratch, in that case, it takes time.
  • You have to rely on the developer or web development partner for the maintenance.
  • Transferring to different CMS might get complicated. 


Custom CMS is for you if your business website requires updates and customization regularly. However, moving the custom CMS to another CMS platform will be difficult in this case.

Final Note

It is critical to consider the above pros and cons when selecting whether a custom CMS or open-source CMS is the best fit for your organization. While open-source CMS offers excellent flexibility, custom CMS codes always hold a high standard. If you want to create a website, mobile application or site that is SEO optimized, custom CMS would fit your requirements nicely.
