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

Ubuntu

  • Free version supported only by community; no official Canonical support without Pro subscription
  • Ubuntu Pro required for enterprise compliance certifications (FIPS, DISA-STIG); free version does not include these
  • Ubuntu Pro pricing is proprietary and varies based on cloud deployment (AWS, Azure, GCP); no published per-machine or per-user pricing
  • Ubuntu Pro + Support adds 24/7 support costs on top of base subscription; total cost for enterprise-grade support not transparent
  • Personal/free tier limited to 5 machines; any larger deployment requires paid enterprise subscription
