Analytics software transforms raw data into actionable insights. This spans web/product analytics (understanding user behavior), business intelligence (analyzing business data), and specialized analytics for marketing, sales, and operations.
The analytics landscape ranges from simple, privacy-focused web analytics (Plausible, Fathom) to complex enterprise BI platforms (Looker, Tableau, Power BI). In between are product analytics tools (Mixpanel, Amplitude, PostHog) that help teams understand user behavior within applications.
Google Analytics has dominated web analytics, but privacy concerns and GA4's complexity are driving adoption of alternatives. Product analytics has matured significantly, with tools that combine event tracking, feature flags, session replay, and A/B testing in unified platforms.
Track user actions—clicks, pageviews, conversions, feature usage. The foundation of any analytics system.
Transform data into charts, graphs, and reports. Good visualization makes data accessible to non-analysts.
Analyze specific user groups—by acquisition source, behavior, or attributes. Essential for understanding what works for whom.
Understand where users drop off and how well you retain them. Core metrics for product and growth teams.
Watch real user sessions to understand behavior qualitatively. Increasingly bundled with analytics tools.
Export or query data in your warehouse. Essential for combining analytics with other business data.
Analytics serves different roles with different needs:
Match your analytics stack to your needs and maturity:
Privacy is reshaping analytics—cookieless tracking, server-side collection, and privacy-first tools are growing. GA4's rocky rollout pushed many to alternatives. Product analytics is consolidating—PostHog's all-in-one approach is gaining share. Warehouse-native analytics (Looker, Mode) serve sophisticated data teams. AI-powered insights are emerging but still early. The market is bifurcating between simple (Plausible) and comprehensive (Amplitude, PostHog).
GA4 remains the default for most websites—it's free and powerful. However, GA4's complexity frustrates many users, and privacy concerns are real. For simple website analytics, Plausible or Fathom offer cleaner alternatives. For product analytics, dedicated tools (Mixpanel, PostHog) are far better. GA4 is best for marketing-focused website analytics where the price (free) outweighs UX frustrations.
Both are excellent product analytics platforms. Amplitude has slightly better visualization and is preferred by larger companies. Mixpanel has cleaner UX and is often easier to learn. Pricing is similar and expensive at scale. For most teams, the difference is minor—pick based on UX preference. Consider PostHog as a more affordable alternative that includes more features.
PostHog is increasingly the answer—generous free tier (1M events/month), combines product analytics + session replay + feature flags + A/B testing. Self-hosting option for privacy. Alternatives: Mixpanel has a good free tier, and Plausible/Fathom are great for simple website analytics at low cost.
If you're asking 'what's our revenue by segment by month' and your analytics tools can't answer it, yes. BI tools (Metabase, Looker, Tableau) query business databases—CRM, billing, operations. Most companies need BI once they're analyzing data beyond website/product behavior. Start with Metabase (free, easy) before investing in expensive tools.
Most teams end up with 2-3: website analytics (GA4 or alternative), product analytics (Mixpanel/Amplitude/PostHog), and BI (if analyzing business data). Resist adding more—tool proliferation creates data silos. Prefer platforms that combine features over best-of-breed for each capability.
