Why we built SessionStack

We love the excitement and joy we all get from creating new things from scratch.

With SessionStack we want to empower you, our fellow developers, customer support and UX experts to minimize the time and energy spend on understanding and reproducing product and website problems, errors and user experience issues. We’d like to think we give you back time to concentrate on creating innovation: great new products, designs, and technologies.
