Analytics
Most analytics tools are built for a team with a dedicated data analyst to interpret them. A solo founder needs the opposite: a handful of numbers that answer 'is this working' at a glance, without a cookie-consent nightmare or a dashboard that takes an afternoon to configure.
1. Plausible
Best privacy-first defaultBest for: founders who want simple traffic analytics without a cookie banner
Plausible is lightweight, cookie-free, and GDPR-compliant by default, which means no consent banner is legally required in most jurisdictions — a real simplification for a small site.
Strengths
- No cookies or personal data collection means no consent banner needed in most cases
- Single-page dashboard shows exactly what most solo founders check daily: visitors, sources, top pages
- Open-source with an option to self-host if you want full data ownership
Watch out for
- Deliberately shallow compared to GA4 — no deep funnel or cohort analysis
- Paid-only; no meaningful free tier beyond a trial
2. Fathom
Best simple dashboardBest for: founders who want Plausible-style simplicity with a slightly different reporting style
Fathom is Plausible's closest competitor — same privacy-first, cookie-free positioning, with its own take on report layout and a built-in uptime-style site monitoring add-on.
Strengths
- Privacy-first and cookie-free, same consent-banner advantage as Plausible
- Clean, fast-loading tracking script that doesn't slow down your site
- Straightforward flat pricing based on pageviews, not user seats
Watch out for
- Smaller integration ecosystem than GA4 or PostHog
- Also paid-only, so it's an added line item rather than a free layer on top of a site you already run
3. Google Analytics 4
Best free depthBest for: founders who want maximum data depth and don't mind the learning curve
GA4 remains the most powerful free option by far — the tradeoff is a genuinely steep interface and the compliance overhead of cookie consent in many regions.
Strengths
- Free with no pageview cap, and the deepest event-level data of any option here
- Integrates directly with Google Ads and Search Console for acquisition analysis
- Widest documentation and community support given how widely it's used
Watch out for
- Interface has a real learning curve — the exact complaint that drives people to Plausible/Fathom
- Cookie/consent requirements and data-collection scope make privacy compliance more work
4. PostHog
Best for product analyticsBest for: founders building a product who want event tracking, session replay, and feature flags together
PostHog goes beyond pageviews into product analytics — funnels, session replay, feature flags, and A/B testing — aimed at SaaS founders who need to understand in-app behavior, not just site traffic.
Strengths
- Generous free tier that covers a genuinely useful volume of events for an early-stage product
- Session replay and feature flags reduce the need for separate specialized tools
- Self-hosting option available for teams that want full data control
Watch out for
- More setup and conceptual overhead than a simple pageview tool if you only need traffic numbers
- Can get pricey past the free tier if event volume grows quickly
5. Microsoft Clarity
Best free heatmapsBest for: founders who want session recordings and heatmaps without paying for them
Clarity is Microsoft's free heatmap and session-recording tool — genuinely free, not a limited trial — making it the easiest way to watch real user behavior on a page without a budget line.
Strengths
- Completely free with no pageview limits, including heatmaps and session recordings
- Very fast to set up — a single script tag with no complex event configuration required
- Useful specifically for spotting UX friction (rage clicks, dead clicks) that pageview counts hide
Watch out for
- Not a full analytics replacement — pair it with a traffic tool rather than using it alone
- Fewer configuration options than PostHog for teams that want deep customization
Questions solo founders ask about analytics
Do I need a cookie consent banner if I use one of these?
Plausible and Fathom are cookie-free by design, which avoids most consent-banner requirements in practice. GA4 and PostHog collect more data by default and typically do require a consent mechanism depending on your visitors' region — check current guidance for your jurisdiction rather than relying on defaults.
Can I run more than one analytics tool at once?
Yes, and it's common — for example, Plausible or Fathom for a fast daily traffic glance, paired with Microsoft Clarity for occasional session-replay debugging when something looks off. Just be mindful of the cumulative effect on page load speed.
Which one should a pre-launch founder start with?
Whichever answers your actual question fastest. If you just want to know how many people visited and where from, Plausible or Fathom is enough. If you're already building a product and need to know where users drop off inside it, start with PostHog instead.
