Great SaaS boilerplate. There are very few open-source alternatives with so many features out-of-the box. So far I've built only one product with it, but if it gets updated and comes out of beta, I might use it again.
Certainly the best Next JS boilerplate app out there. If I had to estimate, easily saves a week worth's of work and serves as a good tutorial for learning the structure of a well-built Next JS application.
