The question comes up every time someone recommends a free, no-account tool: "How does this even stay online? How are they paying for servers?"

It's a fair question. Free tools have to exist somewhere. Bandwidth costs money. Developer time costs money. Even a static website at scale costs something to serve. The assumption is that if you're not paying with money, you're paying with data — your email address, your behavioral patterns, your willingness to be retargeted.

But a growing category of no-login tools operates on entirely different economics. Understanding how they survive explains why the no-login movement isn't a fad — and helps you spot which tools are genuinely giving you something for nothing versus delaying a capture that's coming regardless.
