You might want to be more specific, cloud flare has a lot of different products, and you’re getting answers with differing assumptions.

For the self hosted focus, I use tail scale already, and when (not if) that company gets shitty, I will switch to head scale, or a competitor, or straight wire guard (plus firewall etc).

But I also run web sites on cf, and there’s no real alternative, definitely not for free. I don’t have hundreds of millions to spend on the CDN part, for starters.
