8 product analytics tools compared
Product analytics shows a self-serve team where new users quit, without anyone having to ask them. The bill usually follows events or users, free ones included, so work out what each vendor meters before comparing reports. After that, look for session replay on the plan you can afford, and account-level reports if you sell to companies.

If a security review sets the requirements
Mixpanel Growth puts SAML SSO and warehouse connectors on a plan you can buy without a sales call. 
Pendo meters MAU and quotes every paid plan, with session replay from Core.
Free users, not customers, drive the event bill
If most of your signups never pay, the meter matters more than any report. Trial accounts and logged-out visitors fire events like customers do, and an event meter bills every one of them. Mixpanel Growth starts at $0 a month with 1,000,000 events a month included, and Amplitude Plus starts at $0 a month with 2,000,000. Past those lines both bill per event, so a launch spike raises the invoice whether revenue follows or not. Statsig Pro is $150 a month with 5,000,000 events included: a higher floor, and the same invoice every month up to that volume.
PostHog prices an event by who sent it. On Pay-as-you-go, anonymous events cost $0.00005 each and identified events $0.000198 each, both after the first 1M a month. A long logged-out trial pays mostly the low rate. A product that asks for a login on the first screen pays the identified rate on almost everything, so count both kinds before you compare PostHog with anyone.
Two vendors count people instead of events. Pendo meters monthly active users and quotes every paid plan. 
Countly Flex is $175 a month for 5,000 MAU.
Get session replay on the plan that shows the funnel
The funnel says which step loses people. A replay shows what they did there. Mixpanel, Amplitude, PostHog, Statsig and 
Fullstory include session replay from their cheapest plan, and Mixpanel Growth carries 20,000 replays a month in its base price. 
Heap sells replay as an add-on to Pro and Pendo starts it at Core, both by quote, so get the replay price in writing before your volume grows into it. Experiments follow the same line: Mixpanel, Amplitude, PostHog and Statsig include them from their cheapest plan, and Countly sells them as a Flex add-on.
If you sell to companies, price the account reports
A user count hides the customer account that is quietly going cold. Statsig lists group analytics without tying it to a plan. Mixpanel sells Group Analytics as a paid add-on from Growth, PostHog sells a group analytics add-on, Amplitude starts account-level analytics at Growth, a quoted plan, and Heap puts account analytics in Pro. A consumer app can skip this column.
