Is Quantalog a replacement for PostHog?

Only for the web-analytics part — traffic, referrers, funnels, goals and events. It does not replace session replay, feature flags or experiments, and it has no data warehouse.

Why would I move from PostHog to Quantalog?

Usually to drop the consent banner and the SDK weight when the team only ever used PostHog for pageviews and funnels, and the rest of the platform sat idle.

Does Quantalog need a cookie banner where PostHog does?

Quantalog never needs one; it is cookieless in its only mode. PostHog needs one in its default configuration because it sets cookies and identifies users.

In fairness

When PostHog is the better choice.

Stay with PostHog if you use session replay, feature flags, A/B experiments or its SQL data warehouse. Quantalog does none of those and is not trying to; it is the smaller tool on purpose.
