Fathom Analytics vs Plausible Analytics in 2026: Flat pricing vs open-source flexibility
Both are cookieless GA4 replacements with no consent banners. Fathom bundles every feature into one plan; Plausible splits its Stats API and AI traffic tracking across a tiered, self-hostable structure.
Fathom Analytics
Plausible Analytics- Plausible starts at €9/month for a single site; Fathom starts at $15/month but includes 50+ sites on every plan by default.
- Plausible is fully open-source and self-hostable under AGPL license. Fathom is closed-source, though independently owned with no VC investors.
- Plausible automatically detects and attributes AI referral traffic from ChatGPT, Perplexity, and Claude at no extra setup cost. Fathom has no equivalent AI traffic detection feature.
- Fathom includes API access on every plan. Plausible restricts its Stats API to the Business tier and above.
- Fathom retains data forever regardless of plan. Plausible retains data for 3 years on Starter and Growth, extending to 5 years on Business.
- Plausible connects directly to Google Search Console for query-level SEO data inside the same dashboard. Fathom has no Search Console integration.
- Fathom prices in US dollars; Plausible prices in euros, which adds minor currency friction for US-based teams reconciling costs.
Fathom Analytics and Plausible Analytics are the two most commonly recommended privacy-first alternatives to Google Analytics, and for good reason: both are cookieless, both remove the need for a consent banner, and both are trusted by well-known engineering-led companies. The differences show up in structure rather than philosophy. Fathom charges from $15 a month and includes every feature, including API access and 50+ sites, on that single plan. Plausible starts cheaper at €9 a month but locks its Stats API and Looker Studio connector behind the Business tier, while adding features Fathom does not have at all, including AI referral traffic tracking for ChatGPT, Perplexity, and Claude, plus a fully open-source, self-hostable codebase. Which one wins depends on whether you value a flat, no-decisions plan or a tiered structure with a self-hosting escape hatch.
The tools at a glance
Fathom Analytics
Simple, GDPR-compliant web analytics with cookieless tracking, forever data retention, and no consent banners.
Fathom Analytics is used on over a million websites, including properties for IBM, GitHub, and Tailwind CSS, and is built around the idea that analytics should be insightful without collecting a single cookie or personal identifier. Setup is one script tag on any site or framework.
The pricing structure is deliberately flat: every plan includes API access, at least 50 sites, and forever data retention, so there is no feature you unlock by upgrading, only more page-view headroom and more sites. That simplicity is attractive to agencies who do not want to reason about which tier unlocks which report.
The gap against Plausible is depth in newer categories. Fathom has no AI referral traffic detection, no Search Console integration, and is not open-source, so teams cannot audit the collection logic directly or self-host as an alternative to the hosted plan.

| Pricing model | Based on monthly page views |
| Sites included | 50+ |
| Data retention | Forever |

Plausible Analytics
Lightweight, EU-hosted, privacy-first analytics that replaces Google Analytics without cookies or consent banners.
Plausible Analytics is EU-hosted, collects no personal data, and has over 19,000 paying customers, including teams at Hugging Face, Basecamp, and Ghost. The entire dashboard fits on one page, and the tracking script is 54 times smaller than Google Analytics, with a measurable effect on page speed.
Plausible tracks AI referral traffic from ChatGPT, Perplexity, and Claude automatically, with no setup required, letting teams see which pages attract AI-sourced visits and how those visits convert. It also connects directly to Google Search Console, pulling query and click-through data into the same dashboard as traffic and goals.
The Stats API and Looker Studio connector are gated to the Business plan at €19 a month, which is a real limitation for teams on Starter or Growth who want to pull data programmatically. Plausible's open-source, self-hostable codebase under AGPL is the clearest structural advantage over Fathom for teams that want to run their own instance.
| Feature | Starter From €9/mo | Growth From €14/mo | Business From €19/mo | Enterprise Custom |
|---|---|---|---|---|
| Sites included | 1 | 3 | 10 | Custom |
| Data retention | 3 years | 3 years | 5 years | Custom |
| Stats API | ✗ | ✗ | ✓ | ✓ |
| Looker Studio Connector | ✗ | ✗ | ✓ | ✓ |

Which should you choose?
Fathom AnalyticsPlausible AnalyticsFathom AnalyticsPlausible AnalyticsPlausible AnalyticsFathom AnalyticsFathom optimizes for zero decisions: one plan, every feature, forever retention. Plausible optimizes for depth and optionality: a lower entry price, an open-source core you can self-host, and features like AI referral tracking and Search Console integration that Fathom simply has not built. The Stats API gate on Plausible's Business tier is the one place where Fathom's flat structure genuinely wins on access.
Bottom line
Pick Fathom if you manage many sites, want API access from day one, and do not want to think about tiers. Pick Plausible if you want to track AI-sourced traffic, want Search Console data in the same view, or want the self-hosting option as an insurance policy against future pricing changes. Teams already deep in Google Search Console workflows will feel the Plausible integration advantage immediately.
Frequently asked questions
Is Fathom Analytics or Plausible Analytics better for tracking AI referral traffic?
Plausible is the clear choice here. It automatically detects and categorizes referral traffic from ChatGPT, Perplexity, and Claude with no setup, showing which pages attract AI-sourced visits and how they convert. Fathom has no equivalent AI traffic detection feature as of this comparison.
Which tool is cheaper, Fathom or Plausible?
Plausible has the lower sticker price at €9 per month for one site, versus Fathom at $15 per month for 50+ sites. But Fathom includes API access and forever retention on that entry plan, while Plausible gates its Stats API to the €19 Business tier, so the real cost comparison depends on which features you actually need.
Can I self-host Fathom or Plausible Analytics?
Only Plausible offers self-hosting. Its full codebase is open-source under the AGPL license, and the community edition covers most core features, though some newer dashboard and enterprise features remain cloud-only. Fathom has no self-hosting option at any tier.
Does Plausible or Fathom integrate with Google Search Console?
Plausible connects directly to Search Console, showing search queries, click-through rates, and rankings alongside traffic data in the same dashboard. Fathom does not offer a Search Console integration.
Which tool is better for an agency managing 50+ client websites?
Fathom is the more predictable option for high site counts, since every plan includes 50+ sites by default and additional packs cost a flat $10 per month for 50 more. Plausible caps Starter at 1 site and Growth at 3, so an agency running many sites would need Business or Enterprise, at a higher effective cost per site than Fathom.
