Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
GoAccess
- Analyzes server logs only; no JavaScript snippet for client-side event or user-behavior tracking
- No user session recording, heatmaps, or funnel analysis
- No retention, cohort, or A/B test reporting
- Historical trend analysis is limited to what the log files contain
PostHog
- Self-hosting the full ClickHouse + Kafka + Postgres + Redis stack is heavy; the project actively steers smaller users toward PostHog Cloud.
- Some enterprise features live under a separate proprietary
eelicense, not pure MIT. - The all-in-one breadth means it is more complex to operate than a focused tool like Mixpanel.
Bottom line
Choose GoAccess if you want the lower-effort setup; choose PostHog for the larger community and ecosystem. PostHog has seen more recent development. Open each guide below for deploy steps and the full feature gap.
