Where each one falls short

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

GitLab

  • Baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive
  • PostgreSQL is mandatory; no support for alternative databases
  • Redis or Valkey cache required; adds infrastructure complexity
  • High-availability deployments require inter-node latency below 5 ms; difficult to achieve across geographically distributed sites
  • Requires self-hosting and maintenance; GitLab.com SaaS only available to GitLab team members for administration

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
