WordPress Limitations & Custom Development (What You Should Know)

WordPress powers over 40% of the web—and for good reason. It’s flexible, affordable, and beginner-friendly.
But as your website grows, you may discover limitations that can’t be solved with themes or plugins alone.

That’s where custom WordPress development becomes essential.

This guide explains the real limitations of WordPress and how custom development helps businesses scale safely and efficiently.

🧠 WordPress Is Flexible — But Generic by Default

WordPress is built to work for:

• Blogs

• Business websites

• eCommerce
