| Bottom line | From its public pages, Amplitude has the largest free tier and the lowest listed price at 10 million events. SSO, longer history and scheduled syncs sit on the custom-priced Growth plan, so check those against your needs first. | From its public pages, Heap pairs autocapture with SSO on every plan and four ISO certifications. It publishes no prices and bills by sessions, so expect to install the snippet or talk to sales before you know the cost. | From its public pages, PostHog is the most transparent on price and the most open with your data, with a self-serve HIPAA BAA. Identified events carry a second rate, so estimate your mix of identified and anonymous events before comparing bills. |
