Plausible vs Fathom Analytics: Which Lightweight GA4 Alternative Fits Your Site?
Both are cookieless, script-light alternatives to GA4 built for sites that just want clean traffic numbers without a consent banner. The real decision comes down to how many sites you run and whether you ever want to own your data on your own server.
Both are strong, honest GA4 alternatives, so the tie-breaker is usage pattern, not quality. If you run one or a handful of sites and might ever want to self-host, Plausible wins on flexibility and its open-source Community Edition. If you run many sites, especially as an agency managing client properties, Fathom wins outright because every paid plan includes 50 sites at no extra cost, where Plausible caps sites per tier regardless of your traffic volume.
Privacy-first, lightweight web analytics tools like Plausible and Fathom exist because GA4 solves a problem most small and mid-sized sites do not have. GA4 is built for advertisers who need cross-device identity resolution, audience remarketing, and deep integration with Google Ads, and that scope comes with a real cost: cookies or device identifiers in most configurations, a consent banner in the EU and UK, a sprawling dashboard, and a tracking script that adds meaningful weight to every page load. Plausible and Fathom take the opposite approach. Neither uses cookies, neither collects personally identifiable information, and both anonymize or aggregate visitor data so that in most jurisdictions no cookie consent banner is legally required at all. The tracking script for each is a fraction of GA4's size, roughly 1 to 2 KB versus GA4's script weighing in around 45 KB, and the dashboard is a single page of pageviews, sources, and top pages rather than a multi-report suite.
Teams choose one of these two over GA4 entirely for a few consistent reasons: they do not want to run a cookie banner just to see traffic numbers, they want a dashboard a non-analyst can read in thirty seconds, they are privacy-conscious about handing visitor-level data to Google, or they simply do not need GA4's advertising-attribution machinery because they are not running complex multi-channel ad campaigns. The tradeoff is real: neither tool matches GA4's depth on attribution modeling, audience building, or ads integration. For a marketing site, a SaaS landing page, a blog, or an agency's client portfolio where the question is simply how much traffic, from where, doing what, that tradeoff is usually the right one.
Feature-by-Feature Comparison
| Feature | Plausible | Fathom Analytics |
|---|---|---|
| Cookie use / consent banner | None - cookieless by design, no consent banner required in most jurisdictions | None - cookieless by design, no consent banner required in most jurisdictions |
| Tracking script size | Roughly 1 KB, among the lightest scripts available | Roughly 1.6 to 2 KB gzipped, also very lightweight |
| Open source | Yes, source code published under AGPL license | No - Fathom moved to a closed-source model around 2020; the old open-source "Fathom Lite" is feature-frozen and no longer maintained |
| Self-hosting option | Yes - free Community Edition you run on your own server, full data sovereignty | Not available - Fathom is cloud-only with no self-hosted option |
| Sites included per plan | Capped by tier: 1 site (Starter), up to 3 (Growth), up to 10 (Business), more on Enterprise | 50 sites included on every paid tier by default, more on higher pageview tiers, extra packs of 50 available for $10/month |
| Goals and custom events | Included from the Starter plan up | Included on every paid plan, no tier gating |
| Funnels | Business plan and up only | Not a dedicated funnel-builder feature; Fathom stays intentionally simpler here |
| Ecommerce revenue tracking | Business plan and up | Available via custom events, less purpose-built than Plausible's dedicated revenue goals |
| Uptime monitoring add-on | Not offered | Included on paid plans - alerts you if your site goes down |
| Dashboard/client sharing | Shared links and embedded dashboards on Growth and up | Dashboard sharing and full client sub-accounts on every plan, geared toward agency use |
| Data retention | 3 years (Starter/Growth), 5 years (Business), 5+ years (Enterprise) | Retention scales with plan; EU data isolation available as an add-on |
| API access | Stats API on Business and up | API access included, used commonly for custom reporting integrations |
| Best fit | Single-site owners and small teams who value open source and the option to self-host later | Agencies and anyone running many low-to-mid traffic sites under one account |
Pricing Compared
| Monthly Pageviews | Plausible | Fathom Analytics |
|---|---|---|
| Up to 10,000 | $9/mo (Starter plan, 1 site) | Not offered at this tier - Fathom's lowest plan starts at 100,000 pageviews |
| Up to 100,000 | $19/mo (Growth plan, up to 3 sites) | $15/mo (50 sites included) |
| Up to 500,000 | Scales within the Business tier, roughly $49/mo | $45/mo |
| Up to 1,000,000 | $69/mo (Business plan, up to 10 sites) | $60/mo |
| Up to 2,000,000 | Business tier continues scaling, or Enterprise custom quote | $100/mo |
| Self-hosted | Free - Community Edition, AGPL open-source license, you provide the server | Not available - no self-hosted option at any price |
| Enterprise / very high volume | Custom quote, includes SSO, priority support, and higher API limits | Custom quote starting above roughly 10 to 25 million monthly pageviews |
Both vendors offer an annual billing discount worth roughly two months free. Fathom's flat 50-sites-included model means the per-site cost drops fast for anyone running a portfolio, while Plausible's site caps mean an agency with 15 low-traffic client sites would need at least the Business plan even though total pageviews might be modest.
Pricing figures above reflect published, self-serve rate cards as of September 2026 for both vendors, but both revise tiers and included site or pageview counts periodically. Verify current pricing directly on each vendor's site before budgeting, particularly at the higher pageview and enterprise tiers where custom quotes apply.
Pros & Cons
Plausible
Pros
- ✔ Open source under an AGPL license, with a free, fully-featured self-hosted Community Edition for teams that want full data ownership
- ✔ Cheapest entry point for a single low-traffic site at $9/month
- ✔ Clean, simple dashboard that a non-analyst can read immediately
- ✔ Funnels and ecommerce revenue tracking available for teams that outgrow basic pageview counting
Cons
- ✕ Site count is capped per tier regardless of traffic, so a multi-site portfolio forces an upgrade even at low volume
- ✕ Funnels, custom properties, and the Stats API are locked behind the Business tier
- ✕ No built-in uptime monitoring or dedicated agency client-sharing tooling
Fathom Analytics
Pros
- ✔ Every paid plan includes 50 sites by default, making it the stronger choice for agencies and anyone managing many properties
- ✔ All features, including goals, custom events, and dashboard sharing, are included on every tier with no feature gating
- ✔ Built-in uptime monitoring and EU data isolation options add practical value beyond pageview counting
- ✔ Cheaper than Plausible at most comparable mid-to-high pageview tiers
Cons
- ✕ No free entry tier below 100,000 monthly pageviews, so it is not the cheapest option for a single small site
- ✕ Closed-source and cloud-only, with no self-hosting path if data sovereignty is a hard requirement
- ✕ Fewer advanced analysis features like dedicated funnel-building compared to Plausible's Business tier
Which One Should You Actually Pick
You run a single blog, marketing site, or small SaaS product
Plausible is the cheaper starting point at $9/month for up to 10,000 pageviews, and you keep the option to self-host for free later if your needs or budget change.
You are an agency managing many client sites
Fathom is the clear pick. Fifty sites included on every plan means you are not paying per property, and dashboard sharing per client is built in rather than bolted on.
Data sovereignty or self-hosting is a hard requirement
Plausible is the only one of the two that supports it, through the free, open-source Community Edition running on your own infrastructure.
You want funnels or ecommerce revenue attribution without leaving a lightweight tool
Plausible's Business plan covers this; Fathom stays deliberately simpler and does not offer a comparable dedicated funnel builder.
You want uptime monitoring bundled with your analytics
Fathom includes this on paid plans; Plausible does not offer it at all, so you would need a separate tool.
The Real Decision Isn't Features, It's Shape of Usage
Plausible and Fathom Analytics solve the same core problem in almost the same way: no cookies, no consent banner, a script that barely registers on page-load time, and a dashboard built around the handful of numbers most sites actually check. Feature-for-feature, they are close enough that picking one over the other on a spec sheet alone is not a productive exercise. The decision that actually matters is the shape of what you're tracking: one site or many, and whether you might ever want to run the software yourself instead of paying a monthly subscription for it.
That shape-of-usage question is why the pricing tables above tell a clearer story than the feature tables do. At matching pageview tiers, Fathom is generally the cheaper option, and its flat 50-sites-included model means an agency running a dozen client sites pays the same as an agency running one, as long as total traffic stays within tier. Plausible's per-tier site caps mean the same agency would need to jump to a higher, pricier plan well before its traffic volume alone would justify it. On the other hand, Plausible is the only one of the two with an open-source, self-hostable path, which matters a great deal to teams with strict data-residency requirements or a philosophical preference for owning their own analytics infrastructure, and matters not at all to teams who just want a dashboard they never have to think about maintaining.
What to Verify Before You Commit
Because both vendors publish transparent, self-serve pricing (a genuine point in favor of this category over GA4 360 or Adobe Analytics, where enterprise pricing is never published), verifying the numbers before you commit is straightforward: check your actual monthly pageview count against each vendor's current tier boundaries, and if you manage multiple sites, count them explicitly against Fathom's included-site allowance versus Plausible's per-tier cap. If self-hosting is even a possibility for your team, budget realistically for the server maintenance and update overhead that Plausible's free Community Edition does not eliminate, it just moves the cost from a subscription line item to engineering time.
Common questions
GA4 is free and far deeper on attribution, audience building, and Google Ads integration, so if you run complex paid-media campaigns across channels, GA4 still earns its complexity. But for a site that just needs to know how much traffic it gets, where it comes from, and what pages get read, GA4's cookie-based configuration options, consent-banner requirements in the EU and UK, and multi-report dashboard are more overhead than most teams need. Plausible and Fathom trade GA4's depth for a script that loads faster, a dashboard that takes thirty seconds to understand, and no cookie banner to build or maintain.
Both are built to avoid tracking cookies and personal identifiers entirely, which is the basis for their claim that a consent banner is not legally required under GDPR and similar frameworks in most standard use cases. That said, this is a legal question that depends on your overall site setup, not just your analytics tool, so if consent compliance is business-critical, confirm your specific configuration with legal counsel rather than relying on either vendor's marketing claim alone.
Yes, and it is a relatively light migration compared to moving off GA4. Both tools track the same basic dimensions (pageviews, sources, referrers, goals), so the switch is mostly a matter of re-adding your tracking script and rebuilding any goals or custom events, since historical data does not transfer between vendors.
It depends on what you're optimizing for. Self-hosting the Community Edition costs nothing in license fees but requires you to run and maintain a server, handle updates, and forgo cloud-only features like advanced bot filtering, funnels, and SSO. Most teams without a specific data-sovereignty requirement find the hosted plan's low monthly cost cheaper than the engineering time self-hosting requires.
