Feature-by-feature comparison
The verdict
Google Agent Search is the right choice for teams already on GCP with an active enterprise agreement and compliance requirements that mandate first-party Google products. Third-party APIs are the right choice for teams that need to ship an agent with web search this week, not this quarter. Many teams start with a third-party API to build and validate, then migrate to Google Agent Search when the enterprise contract closes. The practical reality is that procurement bureaucracy, not technical capability, is the primary bottleneck for most enterprise agent projects.
