SaaS could do it, but tend not to be small, library-like things (pure functions, that process information and return the result), but more connected to a real-world service, that you are just accessing through an API...<p>Though maybe I&#x27;m wrong - are there random SaaS offerings like that?<p><i>EDIT</i> Thanks for requesting clarification! Made me realize I do know of some: google&#x27;s data-to-graph-image service (now closed) and various conversions (e.g. text-to-pdf).<p>But these don&#x27;t make money - unique value propositions for libraries is difficult, because of open source alternatives.  That&#x27;s a business problem; not solvable by a new access technology.<p>Perhaps charging for pure software was a historical abberation.
