Laminar vs Phoenix

Our take

Pick Laminar if you're on a agent team who will stay on Free at $0 while they open a first transcript, then Starter at $30/month when they need more storage or Signals credit. Pick Phoenix if you're on a agent team who will self-host Phoenix for $0 (uvx arize-phoenix serve) and only open Arize AX when they want a managed cloud.
