Hello, I've followed North Commerce for many months and i've been on the fence about it. I decided to give the free trial a go (find on their website) and ok, it does seem pretty decent, a nice Woo alternative from what I played about with.
I then decided to re-watch a lot of the youtube videos on their channel and I started to see the potenial and benefits more. I really like the clean UI, much better than Woo and I noted the faster loading speeds, particually on the cart and checkout pages, which also look great.
My biggest concern, like many is the slow development and, the possibility of hitting walls in regards to the lack of 3rd party plugin support. As such you might need to revert back to Woo in some cases or many for that matter but hopefully in the coming future NC will integrate and deliver on all fronts making it a true Shopify alternative.
In the meantime i intend to use NC as a simple, easy and affordable ecommerce platform for my clients. The Bricks integration is a real Plus+10 for me too.
I decided to go all in with tier 4 for unlimited websites and what a bargain! One sale and i'll recoup my investment with profits! I do hope NC continues to develop and stays in business!
(no video review on this one as it's quite an undertaking to cover, but maybe i'll cover it in the near future).
