For most use cases, yes. DataFaucet creates tool endpoints faster, works across all AI clients, and costs less. Vertex AI Extensions make sense if you need deep GCP integration (IAM, VPC, audit trails) or are locked into Gemini-only workflows.
Yes. DataFaucet servers work with Google ADK and any Gemini client that supports MCP. You get the same tool access without building Vertex AI Extensions from scratch.
DataFaucet for most teams. Free tier covers 3 servers. Pro is $29/mo flat. Vertex AI Extensions incur Cloud Run costs, networking, API calls, plus Vertex AI pricing per request. Enterprise at scale may flip this equation.
