Analytics and data model

Amplitude is strongest when a mature organization needs deep segmentation, formulas, behavioral cohorts, lifecycle analysis, monitoring, and reusable governed metrics. Mixpanel makes funnels, retention, cohorts, and flows accessible to a wider product audience. PostHog combines standard product analytics with HogQL/SQL for technical analysis and connects cohorts across replay, flags, experiments, and surveys.

Model identity and accounts first

Identity and accounts remain implementation work. Adding a company property later does not automatically make historical events group-aware.

Amplitude Accounts and Mixpanel Group Analytics require relevant group context; Mixpanel explicitly says the feature cannot be applied retroactively without the necessary historical data work. PostHog distinguishes anonymous and identified events and uses paid Group Analytics for group-level questions. Define user_id, account_id, aliases, membership changes, and deletion behavior before judging any dashboard.

Balance semantic events and autocapture

All three combine explicit events with some autocapture. Use client capture for exploratory paths and server-confirmed events for durable outcomes. Broad capture raises masking, exclusion, retention, and volume obligations; a semantic plan raises taxonomy and change-management obligations. The product analytics instrumentation plan and account versus user adoption guide provide implementation patterns.

Availability does not mean identical depth or inclusion. Filled segments show documented emphasis, hatched means plan-dependent, add-on or early stage — confirm plan-specific qualifications before consolidating.

Replay, experiments, and data infrastructure

Replay and heatmaps

Amplitude offers web and mobile replay plus web heatmaps, with plan and replay entitlements; account-level reporting does not become an account-aggregated replay view. Mixpanel offers web and mobile replay, but mobile requires a client replay SDK. PostHog links replay to users, events, errors, logs, and workflows; its free tier included 5,000 web and 2,500 mobile recordings.

Experiments and product delivery

Amplitude provides native feature and web experimentation, flags, guides, and surveys with plan limits. Mixpanel’s Experiment reporting and Feature Flags were Enterprise add-ons, and no dedicated first-party guide or survey product was documented. PostHog tightly connects experiments, flags, surveys, and errors; experiments are billed with flag requests.

For data movement, separate inbound warehouse sync, outbound export, where queries run, schema control, backfills, latency, deletion, and cost. Amplitude’s older Snowflake warehouse-native mode is legacy and unavailable to new customers. Mixpanel synchronizes eligible warehouse data into the product and sells Data Pipelines separately. PostHog offers a managed warehouse, external sources, HogQL/SQL, destinations, and batch exports, each with its own allowance or rate.

PostHog’s open-source self-hosting path is officially unsupported. Treat infrastructure, upgrades, observability, backups, incident response, privacy, and security maintenance as customer costs—not as a free equivalent to managed service.

Pricing and customer ratings

Public entry signal

Amplitude

Free: 2 million events and 10,000 monthly replays. Plus starts at $0 while under the free allowance; public tiered event pricing then applies.

The Plus card advertised scale to 70 million events while the annual base-tier table stopped at 20 million. Confirm the self-serve-to-quote boundary and expanded packages.

Public entry signal

Mixpanel

Free: 1 million events and 10,000 monthly replays. Growth listed $0.28 per 1,000 events after the first million, before volume discounts.

Confirm Groups, Experiments, Flags, Metric Trees, and Data Pipelines as separately packaged capabilities.

Public entry signal

PostHog

Free: 1 million analytics events, 5,000 web replays, 2,500 mobile replays, and 1 million flag requests, plus separate product meters.

Public pricing separately meters analytics, replay, flags, surveys, errors, warehouse rows, pipelines, and more. Free included one project and one-year retention; pay-as-you-go listed six projects and seven-year retention.

Pricing was checked August 4, 2026. Allowances, rates, plan names, and packaging change; total cost also includes engineering, governance, enablement, privacy, and duplicate tooling.

Which should you choose?

ChooseWhen it is the strongest fitValidate before signing
AmplitudeYou need broad behavioral analysis plus governed data workflows and a connected experimentation or engagement suite.Required modules, account modeling, warehouse workflow, permissions, and contracted volume.
MixpanelYour priority is approachable event analysis, funnels, retention, flows, and cohorts for a wide operating team.Group analytics, replay coverage, governance depth, exports, and growth-tier cost.
PostHogAn engineering-led team wants analytics beside replay, flags, experiments, error tracking, and warehouse tools.Cloud versus self-host boundaries, module meters, mobile support, and the operational burden you will own.

Decision rule: run the same identity, funnel, cohort, replay, governance, and cost exercise in each finalist; breadth on a feature list is not proof of fit.

Where Hymetry fits

Hymetry is not a general replacement for these platforms. Its narrower focus is B2B account evidence: behavior by company, participation by user, product-area context through pages, and the visits behind a signal. It can complement a broad analytics stack when customer-facing teams need company-level adoption and visit evidence by default.

Keep authoritative server outcomes, stable identity, consent, and data minimization regardless of product. No hands-on test, customer outcome, performance result, or replacement claim is implied.

Frequently asked questions

Is Amplitude better than Mixpanel?

Not universally. Amplitude is stronger for broad governed analytical programs; Mixpanel is often the better fit for focused, approachable PM and analyst self-service.

What makes PostHog different?

PostHog combines analytics with replay, flags, experiments, surveys, error tracking, and data tools in an engineering-oriented ecosystem, with separate usage meters for many products.

Do all three support account analytics?

Yes, through package-dependent account or group features. Historical group analysis still requires the relevant group identifiers on the data.

Do all three include session replay?

Yes, but web and mobile allowances, SDK requirements, retention, and package boundaries differ. Account-level analysis also does not guarantee an account-aggregated replay view.

Which is best for experimentation?

Amplitude fits governed experimentation programs, Mixpanel offers experiments and flags as Enterprise add-ons, and PostHog fits engineering teams that want flag delivery and analysis in the same workflow.

Can these products be self-hosted?

PostHog has an open-source self-hosting path, but official documentation describes it as unsupported. No comparable public self-hosted application deployment was documented for Amplitude or Mixpanel.
