Build vs Buy: Should You Write Your Own PDF Tamper Detection?

Understanding internal structures improves code predictability, leading some developers to build custom Node.js EventEmitter instances to mirror browser events. Meanwhile, the decision to build versus buy PDF tamper detection tools is complicated by successful prototypes using pypdf or pdf-lib. While initial prototypes may accurately flag cross-reference sections in sample files, the long-term maintenance costs often exceed the initial development effort, highlighting the trap of focusing only on the obvious starting phase.
