Both vendors have moved to usage pricing and give the seats away, which removes the usual per-analyst argument and replaces it with an event count.
TL;DR
Amplitude gives away 2 million events a month on Free with unlimited seats, session replay, flags and experimentation included, then moves to Plus — starts at $0, first 2 million events free, scaling to 70 million events — before Growth and Enterprise, which are quoted on event-based pricing. Mixpanel gives away 1 million events a month on Free and prices Growth from $0, with an estimator that shows $120 per month on annual billing (or $140 month-to-month) at 18 million events per year. Neither company publishes a per-seat price, so the honest comparison is the free ceiling, the shape of the meter and what the enterprise tier adds.
Amplitude's pricing page opens with free analytics: the Free plan carries 2 million events per month with no time limit and no credit card, unlimited seats, 10,000 monthly session replays, unlimited feature flags, one active experiment, one guide or survey, 2,000 AI feedback records, 5,000 monthly agent sessions, 10 saved charts and one year of data access. Plus starts at $0 with the first 2 million events free and scales with volume up to 70 million events and 700,000 monthly tracked users, adding custom events and formulas, 20 behavioural cohorts, heatmaps, alerts, three spaces and two years of data. Growth and Enterprise are custom and event-based: Growth adds SSO with project permissions, 20,000 replays and monitoring, while Enterprise adds RBAC, data access controls, 50,000 replays and a customer success manager. Startups under $10 million in funding with fewer than 20 employees get one free year of Growth.
Mixpanel publishes Free with unlimited seats, up to 1 million events a month, 10,000 session replays, 1,000 monthly experiment users, up to 10 active feature flags and five saved reports per seat.

Pick Amplitude if
Two million events every month cost nothing, the seats are unlimited, and replay, flags and web experimentation already sit inside that allowance. Mixpanel's free half carries a million events, so the same traffic arrives at an upgrade roughly twice as fast.
Pick Mixpanel if
The estimator prints a number — $120 per month on annual billing at 18 million events per year — before anyone from sales is contacted, and Growth begins at $0 with the first million events free. Amplitude quotes its Plus tier only after an estimate is run.
