We build custom apps, WordPress plugins and Shopify apps — and we build them to last, in code you can read, own and move.
demfilz is a focused software studio. We don't try to be everything to everyone — we do three things well: custom application development, WordPress & WooCommerce plugins, and Shopify apps. That focus is the point. It means the people building your software actually know the platform's quirks, review process and best practices cold.
Too much custom software is a liability dressed up as an asset: bloated, undocumented, locked to one vendor, and quietly abandoned the moment the invoice clears. We started demfilz to do the opposite — to ship software that a business genuinely owns and that any competent developer could pick up and maintain.
You work directly with the developer writing your code — not a sales layer. We write to the platform's own standards (the WordPress Coding Standards, Shopify's app requirements), so what we ship can pass review and live in the official directories. And when it's done, the full source and IP are handed over to you.
Whether it's a plugin, a Shopify app or a full product — tell us the goal and we'll map out how to get there.
