Our take
Pick Haystack if teams who will write Python pipelines (or Studio) and already have a model + store. Pick LangGraph if engineers who will stay on OSS + LangSmith Developer at $0/seat (5k traces) while they open a first _start_ → agent graph, then Plus at $39/seat when they need 10k traces and extra seats — not Enterprise first unless they need SSO / ABAC.
