Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fastlane

  • Requires command-line and Ruby familiarity to configure and maintain Fastfiles.
  • No hosted UI or dashboard; it is a local/CI toolkit rather than a managed service.
  • Community-maintained plugins vary in quality and maintenance status.
  • No built-in analytics or crash reporting; it must be paired with other tools for those needs.

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
