Non-coder but tech-savvy - which platform for building my first SaaS?

Hi

I'm a tech-savvy guy who understands code conceptually but can't really code myself. I've built simple websites before but never a full app. I have a SaaS idea but honestly have no clue how to evaluate if it's technically complicated or not.

I'm a Home Assistant enthusiast, so my mental model for a good SaaS building tool is something like that - a solid core platform where I can keep linking and integrating different services (APIs, payment processors, databases, whatever) as my needs grow. Start simple, then expand modularly without rebuilding everything.

For context: I want custom domain support, ability to plug in new integrations over time, modern UI generation, and ideally something that won't lock me in if I decide to move the project somewhere else.

I've been looking at Lovable since it seems to fit this approach + AI builds the UI, handles hosting, supports integrations, I own the code. But I'm worried I might be missing some major downsides

What would you recommend? Are there gotchas with either of these I should know about? Is there something better suited for a first-time builder with a "Home Assistant mindset"?

Thanks!
