Where each one falls short

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

Bugsnag

  • Owned by SmartBear rather than being independent
  • The free tier covers 7,500 events a month
  • Paid tiers are usage-priced by event volume rather than by seat, so a noisy release raises the bill
  • Enterprise pricing is quote-only

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
