Confused on building a Micro Saas

It sounds to me like you need to build a technical product without much technical domain expertise. The good thing is that learning these technical skills is definitely within reach, though it's important to recognize the amount of time this might take. I will assume that you've seem advice on how to learn to code all over the internet, so the rest of this comment is with the idea in mind that you've come to the reasonable conclusion that you'd like to consider an alternate approach, rather than spending a couple weeks/months learning how to code.

Ask yourself if you might be open to partnering with a technical founder to help build the product. For this to be realistically attractive to a technical founder (ideas are common), you need to provide sufficient proof that your idea has a realistic basis for success; you can achieve this on your own before approaching a co-founder through a variety of means, some of which include:

Conduct customer discovery research and get feedback from who you believe your users would be. Finding out things like which channels you'll be using to market your product also helps answer fundamental questions like "how will people find out about this?"

Perhaps most importantly, you should determine definitively what problem you're solving, and whether or not it's real, and if it is real, whether or not people will pay you to solve it. People buy solutions, not problems. You should also consider whether your proposed solution is THE best way to solve that specific problem, or if there might be other ways to go about it.

You also mentioned you're good with website design, putting together some mock-ups of what you envision your product looking like would also be valuable as a resource to communicate with others and understand the customer journey and user experience.

A symbiotic relationship between founders is common in startups, with one bringing the necessary technical skills to build the product, and another bringing the necessary business development skills to form a profitable venture and grow revenue. If you could see yourself as someone who can fill the business-side role, you might have yourself a compelling basis to partner with someone for a micro-SaaS.

On a final note, if learning how to code is something you're interested in, I've heard good things about the Odin Project: https://www.theodinproject.com/

As someone with a tool that relies on Meta's Instagram APIs - just a friendly warning that they are a pain in the ass to develop with, have pretty bad documentation, and are often buggy. You'll want someone who really knows what they are doing code-wise, or if you tackle it yourself, be ready for some frustration. Good luck!

Get a developer and a designer. You cannot be good at website design if you use no-code tools. Focus on the marketing of the product.

This sounds like a good opportunity to teach yourself how to code.

Honestly while I never used webflow, if you are confident with doing stuff there, I think they have API requests and so on too. Maybe you are not experienced enough to do that yet, but you definitely aren't a -100 either.

Just continue learning, maybe do some more courses on webflow and how to go more into the development side of things (instead of design), webflow makes that pretty easy I heard.

I can also strongly advise that you don't start building immediately, but first test out if people would even actually sign up. The earlier you know that it won't work, the more time you saved. The earlier you know that you have to pivot in a different direction with your tool, the more time you saved.

Since you are confident with webflow already, I guess you can create the mock landing page with that. If you want to save time though, use https://validate.run. It's for busy founders who just want to get something beautiful and high-converting shipped.
