10 Best Philadelphia Web Design Companies That Actually Build Custom Websites in 2026

If you run the marketing for a business in Philadelphia, or anywhere in Pennsylvania and you have started shopping for a new website, you might be a little overwhelmed. There are hundreds of web design companies that promise to design, build, and run a custom website. The truth is that a lot of sites sold as custom start out as an off-the-shelf theme or a page-builder template with a new logo and color palette dropped in.

That is not always a bad thing. For some small businesses, a good template is the right call and call help keep the cost low while still giving you a good web presence for your buyers. It becomes a problem when you are paying custom prices for it, or when you are expecting a return on the investment you made.

We put together this list of Greater Philadelphia and Pennsylvania web design companies that we know do the real work. These companies build 100% custom coded websites for their clients. To put together our list, our criteria was simpl. We proved that they had an in-house or clearly described development team, and a portfolio of original sites that do not all look like the same theme.

These are not paid endorsments of these companies, just a list that we would trust. The list is unranked. We believe that these are truly great PA companies that you should work with.
