PostHog
Pros
- + Free tier resets monthly and covers real work: 1M events, 5K recordings, 1M flag requests and 100K exceptions per month, with every feature available and no credit card
- + Funnel-to-replay-to-error-trace in one timeline replaced a three-tool debugging loop I used to run across separate user IDs
- + Self-hosting under MIT keeps event data inside your own infrastructure — the practical answer I recommend for regulated teams
- + No seat-based pricing at all; adding engineers, PMs and analysts to my projects never changed the bill
- + Billing limits are hard caps you set yourself, so a runaway autocapture config stops at your ceiling instead of at a surprise invoice
Cons
- - Session replay, not analytics, became the largest cost line in my test project once traffic passed the 5K free recordings
- - The interface packs nine-plus products into one navigation; new users I onboarded needed a full day before finding the right tool consistently
- - Self-hosting is a genuine ops burden (ClickHouse, Kafka, Postgres) and the self-hosted build lacks SAML SSO and granular permissions
- - Identified events cost nearly 4x anonymous events in the first paid band, so user-identification choices move the bill more than event volume does
- - Past a billing limit PostHog drops data until the next period — cost control comes at the price of visibility
Mixpanel
Pros
- + Funnels and flows returned in a couple of seconds on my test project, and the flows report surfaced a checkout step-ordering problem within minutes of instrumentation
- + Every plan now bundles session replay, heatmaps, experiments and feature flags, so the small-team plan is no longer analytics-only
- + Free tier covers 1M events, 10K replays and unlimited seats with no credit card — enough to run a real product for months
- + The interface is the most self-serve in the category: non-analysts I onboarded built and shared reports without SQL
- + The pricing calculator shows your exact Growth tier before purchase, so the bill is knowable up front if you use the vendor page
Cons
- - On the free plan, crossing 1M events blocks access to your own reports until the next month or an upgrade
- - Cohorts can be created but not saved on free, and the 10-active-flag ceiling hit before the event allowance did in my test
- - No SQL access to raw events and warehouse export is a paid add-on, so data teams cannot treat Mixpanel as the source of truth
- - B2B measurement (Group Analytics), Data Pipelines and Metric Trees are add-ons or Enterprise-only, which erodes the headline price
- - Third-party Growth pricing figures disagree widely in my research — treat any price not on mixpanel.com as stale
