PostHog vs Heap
PostHog asks you to choose which events and products to turn on, and bills each with its own free allowance. Heap captures interactions through one snippet and counts sessions, and its vendor site says it has joined Contentsquare. The difference is setup style and who owns the product.
Sebastiaan SmitsFounderVendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
Choose PostHog ifyou want to pick products one at a time, cap spend per product, and are comfortable with a US vendor that hosts EU Cloud in Frankfurt.
Choose Heap ifyou prefer automatic capture over writing event code and can accept a Contentsquare parent and sales-led upper tiers.
