Where each one falls short

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

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

Whatagraph

  • The entry Max plan starts at 699 EUR per month and is billed annually, with no monthly billing option shown
  • Only two plans exist and the Prime plan is custom priced with no published rate
  • Public API access, transfer to BigQuery and Looker, a custom report domain and premium integrations all require the Prime plan
  • Data sources are metered as credits at 1 credit per connected data account, so each additional ad account consumes quota
  • Extra credits can be bought only up to the next plan threshold, after which an upgrade is required
  • Moving to either the Max or Prime plan requires booking a call with sales rather than self-serve upgrade
  • The free trial is 14 days
