Fathom Analytics Alternatives

PostHog

Free plan

9.2 /10

PostHog is the all-in-one developer analytics platform — product analytics + session replay + feature flags + A/B testing + surveys + error tracking + LLM analytics + data warehouse. Free tier is absurdly generous: 1M events, 5k replays, 1M feature flag requests, 100k error events, 1.5k surveys, $20 in AI credits — all monthly. For most early-stage SaaS products, PostHog Free is a complete product analytics stack.

• Free tier is the most generous in analytics — replaces $200-500/mo of separate tools
• All-in-one platform (8 products) reduces tool count + consolidates data + saves money
• Unlimited team members on Free tier — competitors charge per seat

Plausible Analytics

Free trial

9 /10

Plausible is the privacy-first Google Analytics replacement. Starter at $9/mo gets you cookieless analytics with no consent banner requirement (legal in EU without asking permission). Open-source means you can self-host for free if you prefer. For marketing analytics on small-to-mid sites, Plausible is the cleanest choice.

• Legal in EU without cookie consent banners — saves $500-5k/year in compliance work
• Open-source — self-host on any VPS for $5-10/mo if you want maximum cost control
• Starter at $9/mo is the cheapest privacy-first analytics with 1 site

Mixpanel

Free plan Free trial

8.7 /10

Mixpanel is the product analytics leader — built for tracking user behavior through SaaS products, not just website pageviews. Free tier at 1M events/mo is category-leading — enough for most small-mid SaaS apps to use indefinitely. Growth tier charges $0.28 per 1,000 events after the first million — affordable at small scale, expensive at enterprise scale.

• Free tier with 1M events/mo and unlimited seats is the most generous in product analytics
• Funnels, retention cohorts, user flows are built for SaaS behavioral analytics — not retrofitted marketing tools
• Spark AI query builder on Growth lets non-technical users ask natural language questions

Matomo

Free plan Free trial

8.5 /10

Matomo is the long-standing Google Analytics alternative — more feature-rich than Plausible/Fathom, with session recording, A/B testing, and heatmaps as options. Cloud Starter at €29/mo covers 50k hits and 30 websites. On-Premise is completely free forever with unlimited everything — you just need a server. For data sovereignty requirements, Matomo self-hosted is the gold standard.

• On-Premise self-hosted is completely free forever with unlimited hits/sites/team — unbeatable value for technical teams
• Feature depth (heatmaps, session recording, A/B testing, tag manager) dwarfs Plausible/Fathom
• GDPR/HIPAA compliance hardened — data sovereignty guaranteed on self-host
