Short answer: it depends on what you need most (simplicity/privacy, event/product analytics, or zero-cost). Top practical picks for a solo founder:
- Plausible
- What: simple, privacy-focused web analytics
- Pros: super easy to set up, clean UI, GDPR-friendly, low cost (~$9–$29/month depending on traffic)
- Cons: fewer advanced features (no full session replay, limited funnel complexity)
- Good if: you want quick actionable metrics and minimal maintenance.
- Fathom
- What: simple, privacy-first alternative to GA
- Pros: easy, fast, privacy-friendly, clear dashboards
- Cons: similar trade-offs to Plausible; paid
- Good if: you like Plausible but prefer Fathom’s UI/feature set.
- Google Analytics 4 (GA4)
- What: full-featured, free (at small scale) analytics by Google
- Pros: powerful event tracking, free, integrates with Google Ads/BigQuery
- Cons: steep learning curve, privacy/cookie complexity, noisy default data model
- Good if: you want a robust, no-cost solution and are willing to learn/configure it.
- Mixpanel
- What: product- and event-focused analytics
- Pros: excellent funnel/retention/event analysis, cohorting, A/B support
- Cons: can get pricey as you scale; more setup work
- Good if: you need deep product analytics (SaaS, apps).
- PostHog
- What: open-source product analytics + session recording (self-host or cloud)
- Pros: powerful and flexible, self-hosting keeps costs down and data private
- Cons: self-hosting requires maintenance; cloud plan costs apply
- Good if: you want product analytics + recordings and control over data/costs.
- Microsoft Clarity
- What: free session recordings and heatmaps
- Pros: free, easy to install, session replay + funnels
- Cons: limited advanced analytics; privacy considerations
- Good if: you want free session replays to understand UX.
- Umami / Matomo
- Umami: lightweight open-source similar to Plausible (self-hosted or third-party hosts).
- Matomo: full-featured GA alternative you can self-host (more setup/maintenance).
Which to pick (two quick recommendations)
- If you want minimal fuss, privacy, and straightforward insights: Plausible.
- If you want powerful free analytics and don’t mind complexity: GA4 + Google Tag Manager.
- If you need product/event analytics and may scale: Mixpanel (or PostHog if you prefer open-source/self-hosting).
Quick setup tips for a solo founder
- Track a few key metrics: signups, activation, paid conversions, retention. Don’t track everything.
- Use UTM parameters for marketing channels.
- Set up event tracking for key actions (signup, trial start, add-to-cart).
- Use simple dashboards and weekly reviews—actionability beats raw data.
- Consider privacy/cookie rules for your region (even for small sites).
