Add Memberstack to manage user profiles

Hey all!

I’m really new to AppGyver so still trying to piece together my understanding of best practices. I’m trying to allow users on my site and in the past I’ve used memberstack to manage users data.

Does anyone have experience of thoughts on if I should continue with Memeberstack or use an alternative such as Firebase or another suggestion.

Memeberstack Front-end API information -

Many thanks!

Looks legit, though the integration point would be their REST API:
