Where each one falls short

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

Yarn

  • Yarn 2+ (Berry) has limited ESM support which can be a constraint for some projects
  • Smaller ecosystem and community compared to npm, though still substantial
