When detection failures cascade into business problems faster than infrastructure costs accumulate, headful browsers justify their resource overhead through reliability.
Headless browsers cut infrastructure costs by 67% through raw speed, but detection challenges reveal when engineering investment beats resource efficiency.
When web agents fail to extract data that's clearly visible on the page, the infrastructure knowledge about where to find it and what it means has broken.
Long-running workflows require checkpoint coordination across distributed fleets—serialization, state tracking, cleanup routines, and synchronization delays that compound.
Production teams restart workflows from scratch because checkpoint infrastructure costs more than accepting occasional failures at scale.
Teams confuse what they're evaluating—behavior, capabilities, reliability—with how they run evaluations, creating mismatches between measurement methods and what actually matters operationally.
Preserving complete page state costs more upfront but becomes essential infrastructure when the web surprises you in unpredictable ways.
