|---|---|---|
| Approach | Open-Source All-in-One | Digital Analytics Suite |

From the Product Analytics Platforms Buyer's Guide, updated June 2026. 8 vendors evaluated.
PostHog
One open-source stack covers all of it, and it is built for engineers: product analytics, web analytics, session replay, feature flags, experiments, surveys, a CDP, and a data warehouse together, with an MIT-licensed core you can self-host for data control and residency or run as managed cloud, a generous free tier, transparent usage-based pricing, and one of the most actively developed tools in the space. It is engineering-led by design, so non-technical product teams get less hand-holding than in Mixpanel or Amplitude. Self-hosting is only advisable at modest event volumes before migrating to cloud, so “free and self-hosted forever” is a misread, breadth means each module is strong rather than always the deepest, and governance tooling is maturing.
Amplitude
The enterprise standard for behavioral analytics, and still the deepest: funnels, retention, paths, and behavioral cohorts with mature governance and a managed tracking plan, expanded into a broader digital-analytics platform covering experimentation, session replay, guides and surveys, and its own CDP, with a preferred partnership alongside Twilio Segment, a strong AI direction, and a large skills base. Monthly-tracked-user pricing climbs quickly and surprises teams that instrument broadly, the expansion into a full suite means more surface area to license and scope, data lives in Amplitude’s store by default so warehouse-native purists weigh export and reconciliation, and the depth carries a learning curve for casual users.
