Do you think I should focus more on the developer angle or integrating with (for example) Shopify?

I've been building https://parrot.dev, and like all good software engineers, I just keep building it without actually focusing on trying to get people to actually use it. It initially started as something that my brother needed for his clients (SMBs, that needed to send promotions to their customers). It's been churning along all right with him using it, but not really making any money (yay family). Now I'd like to take it and really push it to see if it's worth continuing to invest effort into, but I'm not sure that the developer angle is the way to go, or whether it's worth trying to make a Shopify App and target the eCommerce directly. I'm sure there are plenty of problems with the current website itself as well. This is not REALLY a roast my landing page request, though I'm always open to hearing a little feedback because I have a bad habit of operating in a vacuum. Thanks everyone for your time :)
