Yes, developers regularly sell WordPress themes, either through marketplaces like ThemeForest and Elegant Themes, or directly through their own site.
Licensing Requirements
WordPress themes must comply with the GPL (General Public License), meaning the PHP code must remain freely distributable — you can still charge for the theme package, support, and updates.
Where to Sell
Popular routes include ThemeForest, Creative Market, and self-hosted sales through a personal storefront with a licensing/update system.
What Makes a Theme Sellable
Clean code, solid documentation, regular updates, and responsive design are what separate a theme that sells from one that doesn’t.
Key Takeaway
Selling WordPress themes is a legitimate business model under GPL rules. If you need a professionally built site instead of building your own theme, see our Divi web design services.
