OP isn't really arguing against SaaS (after all, OP recommends in the end either Cloudflare or Supabase, which are provided as a service...), that's just the clickbait title, rather OP is arguing against signing up for a hundred different vendors and the overhead of commercial relationships with a hundred different vendors.
Which is... not really controversial. Fewer vendors makes your life easier. Fewer dependencies makes your life easier. It would be awesome if you could build your entire product based on the standard library alone! Sadly... that's not really realistic. Nice pipe-dream though.
Thanks! I think you summarized exactly what I was saying, and pointing out that I had a clickbait title. My goal here is if you're starting out with something new, consider reaching for a platform rather than a bunch of services.
The reason why I really love Cloudflare is because of their bindings. A lot of the time you are simply using fetch, so request and response to interact with their services. It feels as if fetch has become like the Unix pipe of the web.
