Pathfinder

Pathfinder is a common name for a tool that explores real user behavior as a tree or flow diagram, to discover common routes and branch points without a prior hypothesis.

Pathfinder is not a kind of analysis but the interactive surface of path analysis; it turns the same forward-and-backward flow idea into an explorable view where the user can step ahead or back from any node. Its value is exploration: when you do not know what users do and are hunting for unexpected behavior, Pathfinder is the starting point, and you later monitor what it reveals as a fixed funnel. The same limits of path analysis apply here: combinatorial explosion makes the “other” node large and the top path's share small, so Pathfinder is good for discovery but a funnel is the better tool for measuring one specific route precisely. The name Pathfinder is specifically tied to Amplitude's tool, but the same capability exists under other names such as Paths or Flows in other tools.
