01
PostHog Free Tier
~$0.00031/event  ·  Best open-source option
PostHog's free tier covers 1 million events/month — enough for most startups through Series A — and includes feature flags, session recordings, A/B testing, and product analytics in one platform. Self-hosted option gives full data ownership. Limitation: the breadth of features creates decision paralysis for first-time users; new teams often spend 2-3 weeks configuring instead of shipping.

9.2/10
02
Mixpanel Free Tier
~$28/mo  ·  Best funnel analysis
Mixpanel's funnel and retention charts are the clearest in this category — the "where are users dropping off" question takes 3 clicks vs. 15 in Google Analytics. Free tier covers 20 million events/month with 90-day history. Limitation: Mixpanel's event-based model requires thoughtful instrumentation upfront; poorly defined events create dashboards that answer the wrong questions.

03
Amplitude Free Tier
~$49/mo  ·  Best for product teams
Amplitude's Journeys chart maps every path users take through your product simultaneously — not just the path you predicted. The Compass feature automatically surfaces which behaviors correlate with retention. Limitation: the free tier caps at 10 million events/month, and the jump to $49/month is steep for early-stage teams with tight budgets.

04
June Free Tier
~$149/mo  ·  Best for B2B SaaS metrics
June is purpose-built for B2B SaaS — it tracks company-level metrics (MRR by account, feature adoption by company) that Mixpanel and Amplitude require custom implementation to produce. Time-to-first-B2B-report is under 15 minutes with the Segment or Rudderstack integration. Limitation: the free tier is limited to 1,000 monthly active users; the $149/month jump is large for pre-revenue teams.

05
Google Analytics 4 Free Tier
~Free  ·  Best for content and SEO
GA4 is the only free analytics tool with direct Google Search Console integration — organic keyword performance and on-site behavior appear in the same report. For content-driven businesses, this is the most important data connection in analytics. Limitation: GA4's event model requires implementation work to match Universal Analytics functionality; the UI has a steep learning curve for non-technical founders.

06
Heap Free Tier
~Free trial / contact for pricing  ·  Best retroactive analytics
Heap captures every user interaction automatically without pre-defined events — you can run funnel analysis on actions you never planned to track. For teams that shipped without instrumentation, Heap surfaces data retrospectively. Limitation: the always-on capture creates large data volumes that push you to paid plans quickly; pricing is custom and typically higher than Mixpanel or Amplitude.

07
Plausible Mid-Range
~$9/mo  ·  Best privacy-first web analytics
Plausible is cookieless, GDPR-compliant by default, and requires no cookie consent banner — the setup adds one script tag and delivers pageviews, bounce rate, and top sources in 24 hours. Dashboard loads in under 1 second vs. 5-8 seconds for GA4. Limitation: Plausible is web traffic analytics only — no event tracking, no user journeys, no funnel analysis.

7.9/10
08
Fathom Mid-Range
~$14/mo  ·  Best simple traffic analytics
Fathom's privacy-compliant dashboard delivers the 5 traffic metrics that matter (pages, sources, countries, devices, referrers) with a load time under 500ms. EU isolation option stores data exclusively on EU servers for GDPR compliance. Limitation: same constraint as Plausible — traffic analytics only, no product or user behavior tracking.

7.7/10
09
Segment Free Tier
~$120/mo  ·  Best data infrastructure
Segment is not an analytics tool — it's the infrastructure that feeds your analytics tools. Instrument once and route events to Mixpanel, Amplitude, PostHog, and your data warehouse simultaneously. Changing analytics tools later requires zero re-instrumentation. Limitation: Segment adds a layer of complexity; solo founders and very early-stage teams pay a setup cost that dedicated analytics tools don't require.

Frequently Asked Questions

What analytics tool should a pre-revenue startup use?

PostHog's free tier is the default answer — 1 million events/month, session recordings, and feature flags at no cost. If you're a B2B SaaS, add June's free tier alongside it for company-level metrics. Avoid Google Analytics 4 as your primary product analytics tool — it's built for content and marketing, not product behavior.

What's the difference between Mixpanel and Amplitude?

Both track user behavior and funnels. Mixpanel is stronger on ad-hoc queries — analysts who want to slice data in novel ways prefer it. Amplitude is stronger on automated insights — Compass surfaces retention correlations without analyst input. For a founding team without a dedicated data analyst, Amplitude's automated surfaces provide more out-of-the-box value.

Do I need Google Analytics if I'm using Mixpanel?

Yes, for different reasons. Mixpanel tracks what users do inside your product. Google Analytics tracks how they find you — organic search keywords, ad campaign performance, and referral sources. They're complementary, not competing. Run both: GA4 (free) for acquisition, Mixpanel (free tier) for product behavior.
