Pick PostHog if
product / eng teams who will stay on Cloud Free $0 (1M events, 5K replays, 1M flag requests, 1,500 surveys, 100K exceptions, 1 project, no card) while they ask a first Insight, then raise a billing limit when a launch week would freeze at the cap — or self-host when they will run the stack.
