PostHog vs Smartlook
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Free tierWhat drives the bill
The metric that actually scales your invoice.
Usage-based pricing per product with a substantial free tier; most small teams stay free indefinitely.
End of Sale is in effect, so there is no current list price for new buyers: Cisco stopped new subscriptions on 31 May 2026, existing customers could renew only until 31 August 2026, paid subscriptions end 31 August 2027 and the platform is decommissioned with data deleted on 30 September 2027. Export anything you need before then.

Strengths
- Replaces four or five separate subscriptions with one bill and one SDK.
- Free tier is large enough for real production use at startup scale.
- Open source with a credible self-hosting path.
- Genuinely good native mobile replay, including Flutter and React Native.
- Always-on event tracking without pre-instrumentation.
- Reasonable pricing for mid-sized traffic.
Limitations
- Individual modules are less deep than category specialists.
- Self-hosting at scale is a serious infrastructure undertaking.
- The product surface changes fast, which means occasional churn.
- End of life announced by Cisco: sales closed 31 May 2026, dashboards and historical data go on 31 August 2027.
- Web analytics features are behind Contentsquare and FullStory.
- Interface is less refined than the market leaders.
