They also usually don't want to self-serve. IMO this became abundantly clear once I saw who was using bolt.new and Lovable and what was being built. You'd think these would be perfect fits for non-technical business owners, but after talking to them more it turns out they just don't have the time or interest to spend hours on building some little marketing site, and want it to be someone else's responsibility. Conversely, I would never build something with Framer and have no interesting in allowing some fly-by-night agency hold my site hostage, but they do a lot better at actually delivering value to end users without making them spend their time on tech stuff they don't care about.
Conversely, the kind of person spending hours building a site on Lovable for some SaaS product nobody will ever use has an abundance of time and doesn't really want to pay for anything. Most of the time they won't even put their own name on the site lol. You just don't want to deal with that kind of person IMO. Cloudflare and Github allow it because there's a small chance that a small portion of that kind of person ends up actually making something valuable, and because they have a different cost structure due to their affiliations with massive infrastructure holders.
I got very, very close to launching a vertical static site hosting product a few months ago but eventually realized this was kind of a market for lemons. Our own site is on a Lovable-like platform we built that uses our own svelte-baesd FOSS static site generator called Statue. But in using it to try to make some visualization on our own site, and vibe-debug stuff like a non-technical customer would (this thing on this page is broken in this way) I realized that this wouldn't actually feel like magic to someone who values their time, or isn't getting paid a salary to be a web developer and doesn't understand/care that it's still quite labor-intensive to do this.
IMO the real money is in actually being willing to take accountability/responsibility for building someone's site, and building real tooling around it that works for non-developers AND developers, which is what we're building towards now. It's historically been treated as a kind of low-prestige/uninteresting/unscalable business doing agency web stuff, but if you can figure out how to make it scalable and give people beautiful websites, and not make people who value their time wade through slop, there's immense opportunity.
