As a more than 10 years old agency, we work on different projects with differents frameworks and needed a lot of same features. To solve that, we tried to find a way to standardize things and concepts into small reusable packages using the concept of polymorphic entities and « conventions over configuration ». Having done these packages allowed us to reuse it in different projects at Cherry Pulp.
We use UpToolkit now in many successful projects. It helps us to quickly build a project from a web/app/mobile app that connects thousands of families, a local products ecommerce, to a platform that helps thousand of victims of floods !
This is a digital agency maintained tool, up to date and it's UP dated !
