The decision, in plain words
For a solo builder at 500,000 tracked events/month and a $50.00/mo budget for the analytics platform slot, PostHog leads at 99% fit and $0/mo. The two rules doing the work: budget fit (Runs free at your usage — $0 vs your $50/mo budget); batteries included (Bundles session replay, feature flags, funnels, heatmaps — fewer services to glue at team size 1).
The gap to Mixpanel (91% fit) is wide at these inputs — you'd need to change your requirements, not your taste, to flip it.
