Gotchas - check before you buy

high

Self-hosting the open-source library means you own patching critical CVEs

medium

Pay-per-use SaaS API: costs scale with document volume, hard to forecast

medium

Switching parsers later means re-parsing everything and pipeline rework

low

Full library is heavy enough that the community maintains lightweight forks
