Perl & Interchange


Fremer has a long history with Perl. In fact, our first dynamic websites were written in Perl. We moved beyond CGI scripts to the Interchange application server to custom MVC frameworks and then POE, Catalyst, and Dancer. We still support many Perl applications and are experienced migrating to newer Perl and CPAN modules versions and troubleshooting performance problems.

E-commerce expertise

Our developers also know the ins and outs of ecommerce with Perl and can advise you on usability, promotions, merchandising, marketing, SEO, search, inventory management, fulfillment, and much more.

Customizations to set you apart

With some other ecommerce packages, you can only pick from available features and take what you get. But a business needs to stand apart from the competition. With Interchange, every aspect of your store can be customized and enhanced. Over the years, Fremer programmers have gained experience customizing every part of Interchange. Our consultants work closely with you to design cost-effective custom solutions that deliver real value.


Your business is more than a website. Chances are you have internal systems for your inventory, fulfillment, accounting, or customer service. Fremer’s developers can work with you to harmoniously integrate Interchange with your existing systems and third-party services to make your business run more smoothly.

Stable & scalable

Over the years Fremer engineers have fine-tuned Interchange and other Perl codebases for maximum stability and performance. We make code work well for small sites on shared hosting accounts, mid-sized sites on dedicated servers, and large sites on dozens of load-balanced application servers backed by replicated databases. Our team can help you grow your site as fast as you need, handling millions of products and hundreds of thousands of transactions on a daily basis. With Fremer, your business won’t outgrow your website.
