PostHog Amplitude vs PostHog
A side-by-side Analytics & BI comparison of Amplitude and PostHog — capability coverage, pricing, and stack fit, with 61 of 64 recorded cells citing the vendors' own documentation. No referral fees; the data is ours.
Catalog verdict
Overlapping — These overlap, and plenty of teams deliberately run both.
Both are product analytics platforms covering event tracking and analysis (funnels/cohorts/experimentation), but PostHog also bundles adjacent dev tools (like feature flags and session replay) that some teams keep alongside a dedicated analytics suite.
Drafted by an AI model and accepted into the catalog; overlap verdicts are not all checked by hand.
Switching takes real work. A judgement, not computed from the capability data.

Not offered means the evidence sweep read the vendor's documentation and did not find it — hover to see the page it checked. — means no verdict either way. Hover a recorded cell to read its evidence and source; a cell with no source says so, and each cell says whether an AI pass or a person set the grade.
