All 5 Fathom Analytics alternatives
Compared: open-source alternatives to Fathom Analytics
| Alternative | Best for | Standout | Biggest weakness | Learning curve | Price |
|---|---|---|---|---|---|
| Fathom Analyticsreference | website owners who want GDPR/CCPA-compliant analytics without cookie-consent banners and don't need Google Analytics' behavioral-targeting depth | No cookies and no individual user tracking, which the company says removes the legal requirement for a cookie-consent banner under GDPR, CCPA, and ePrivacy rules. | No free tier at all, and Fathom says it never runs discounts or promotions, so smaller sites pay the same $15+/month starting rate as sites with far more traffic relative to what a free tool like Google Analytics or Plausible's lower tiers would cost. | Low | From $15/mo |
| Matomo | organizations that need GDPR-compliant web analytics with full ownership of raw visitor data, either self-hosted for free or on a paid Cloud/On-Premise support plan | A choice between a genuinely free, unlimited self-hosted Community edition and paid Cloud/On-Premise tiers that include all features (heatmaps, session recording, A/B testing) rather than gating them behind higher-priced plans. | Cloud and On-Premise pricing is published only in EUR, not USD, which complicates budgeting for US-based buyers, and self-hosting the free Community edition requires ongoing server maintenance and updates that a hosted tool like Google Analytics doesn't require. | Moderate | Free |
| Umami | developers and privacy-conscious teams who want cookie-free, GDPR-compliant web analytics they can self-host for free or run as a lightweight paid cloud service | Fully open-source MIT-licensed core that can be self-hosted for free with no usage caps, while the tracking script itself stays under 2KB for minimal site performance impact. | Cloud pricing jumps from free (Hobby, 1 website) to $20/month (Pro, 20 websites) with no smaller intermediate paid tier, and session replay adds a metered per-replay cost on top of the flat monthly fee. | Low | Free tier · paid from $20/mo |
| Plausible | website owners and agencies who need GDPR-compliant analytics without a cookie consent banner or Google Analytics' complexity | A tracking script reported to be 54 times smaller than Google Analytics', combined with a fully open-source, self-hostable codebase under AGPLv3. | There is no permanent free tier, only a 30-day trial, and the hosted cloud plans are priced by pageview volume, so a high-traffic site can hit tier limits and need to upgrade even if it only wants basic metrics. | Low | From $9/mo |

Plausible1.Matomo — best Fathom Analytics alternative for organizations that need GDPR-compliant web analytics with full ownership of raw visitor data, either self-hosted for free or on a paid Cloud/On-Premise support plan
Matomo is the best Fathom Analytics alternative for organizations that want a free, unlimited self-hosted analytics deployment with full data ownership. Matomo's Community edition is free forever, self-hosted, with unlimited users and unlimited monthly hits, an option Fathom Analytics doesn't offer at any price since it's closed-source and hosted-only starting around $15/month. Matomo markets 'all features included' across its tiers rather than gating heatmaps, session recording, and A/B testing behind higher-priced plans the way some competitors do, and its GitHub repository has over 21,000 stars and 31,000+ commits, one of the most established open-source analytics projects. Matomo holds a 5.0/5 rating from 5 Product Hunt reviews. Fathom is still the better choice for anyone who wants published USD pricing and no server maintenance: Matomo's Cloud and On-Premise pricing is listed only in EUR, not USD, complicating budgeting for US-based buyers, and self-hosting the free Community edition requires ongoing server maintenance, updates, and scaling that Fathom's fully managed hosted service avoids entirely.
Compared to Fathom Analytics: a free, unlimited self-hosted Community edition with no user or hit caps, all features (heatmaps, session recording, A/B testing) included rather than gated by tier, one of the most established open-source analytics projects (21,000+ GitHub stars)
Wins:Free, unlimited self-hosted Community edition with no user or hit caps, an option Fathom Analytics doesn't offer at any price · Markets all features (heatmaps, session recording, A/B testing) included across tiers rather than gating them behind higher plans · One of the most established open-source analytics projects, with 21,000+ GitHub stars and 31,000+ commits
Loses:Cloud and On-Premise pricing is listed only in EUR, not USD, complicating budgeting for US-based buyers · Self-hosting the free Community edition requires ongoing server maintenance, updates, and scaling that Fathom's hosted service avoids · Community edition support is limited to community forums, unlike Fathom's paid support included with every plan
Pros
- Free, self-hosted Community edition has no traffic or user caps and is open source under GPL-3.0.
- All plans include the same core feature set (heatmaps, session recording, A/B testing) rather than gating advanced features behind higher tiers.
- GDPR-friendly first-party and cookieless tracking modes without requiring a separate compliance add-on.
- Raw, unsampled data access and 100+ integrations, including BigQuery data warehouse connectors.
Cons
- Cloud and On-Premise pricing is listed in EUR only, adding currency-conversion friction for USD-budgeting buyers.
- Self-hosting the free edition requires ongoing server maintenance, updates, and scaling that a fully hosted tool avoids.
- Community edition support is limited to community forums, with paid email/priority support reserved for Cloud and On-Premise plans.
- Enterprise-scale pricing (EUR3,400/month and above) is significantly higher than pure-cloud analytics competitors at similar traffic volumes.

2.Umami — best Fathom Analytics alternative for developers and privacy-conscious teams who want cookie-free, GDPR-compliant web analytics they can self-host for free or run as a lightweight paid cloud service
Umami is the best Fathom Analytics alternative for teams that want both a genuinely free self-hosted option and a free hosted cloud tier to start on. Umami's MIT-licensed core can be self-hosted via Docker for free with no usage caps, and its Cloud Hobby tier covers one website and up to 100,000 events per month at no cost, options Fathom Analytics doesn't offer at any price since it's hosted-only starting around $15/month. Umami's tracking script stays under 2KB, comparable in lightness to Fathom's own 2kB script, and its Pro cloud tier costs $20/month for 20 websites and 1 million events, a lower entry point than Fathom's roughly $15-45/month sliding scale once multiple sites are involved. Fathom is still the better choice for anyone who wants a more established review record: Umami's cloud pricing jumps from free (Hobby, 1 website) straight to $20/month (Pro, 20 websites) with no smaller intermediate tier, and session replay is metered on top of the flat monthly fee, while Fathom's pricing scales smoothly with pageview volume and includes unlimited ecommerce and event tracking on every plan.
Compared to Fathom Analytics: a free self-hosted MIT-licensed core with no usage caps, a free Cloud Hobby tier (1 site, 100k events/month), a tracking script under 2KB
Wins:Free self-hosted MIT-licensed core with no usage caps, an option Fathom Analytics doesn't offer at any price · Free Cloud Hobby tier covers 1 website and up to 100,000 events per month at no cost · Tracking script stays under 2KB, comparable in lightness to Fathom's own 2kB script
Loses:Cloud pricing jumps from free (Hobby, 1 website) straight to $20/month (Pro, 20 websites) with no smaller intermediate tier · Session replay is metered on top of the flat monthly fee, adding cost beyond the base subscription · Thinner review record (11 Product Hunt reviews) than more established analytics tools
Pros
- Self-hosted core is fully open source (MIT license) with no event or website caps beyond your own server capacity.
- Tracking script is under 2KB, minimizing performance impact compared to heavier analytics scripts.
- No cookies, no cross-site tracking, GDPR-compliant by default.
- Cloud Hobby tier is free for one website and 100,000 events/month with no credit card required.
Cons
- Cloud pricing jumps from free (Hobby, 1 website) to $20/month (Pro, 20 websites) with no smaller intermediate tier.
- Session replay is metered on top of the flat monthly fee ($0.005 per replay beyond the 5,000 included on Business).
- Self-hosting requires running and maintaining your own Docker deployment and database rather than a fully managed service.
Pricing: Free tier · paid from $20/mo — Free (Hobby, 1 site) or $20/month Pro (20 sites) vs Fathom Analytics' roughly $15-45/month sliding scale by pageviews (verified undefined NaN, NaN)
3.Plausible — best Fathom Analytics alternative for website owners and agencies who need GDPR-compliant analytics without a cookie consent banner or Google Analytics' complexity
Plausible is the best Fathom Analytics alternative for anyone who wants a lighter tracking script and the option to self-host for free. Plausible's Starter cloud plan costs $9/month for up to 10,000 monthly pageviews, cheaper than Fathom Analytics' roughly $15/month starting price, and its tracking script is reported to be 54 times smaller than Google Analytics', reducing page-load overhead further than Fathom's own 2kB script. Plausible's source code is published on GitHub under AGPLv3 with a free self-hosted community edition, an option Fathom Analytics doesn't offer at any price since it's closed-source and hosted-only. Plausible holds a 4.6/5 rating from 8 Capterra reviews. Fathom is still the better choice for anyone who wants unlimited event and ecommerce tracking on every plan without exception: Plausible has no permanently free tier on its hosted cloud, only a 30-day trial, matching Fathom's own lack of a free tier, and funnels, custom properties, and the Stats API are locked behind Plausible's pricier Business tier, while Fathom includes unlimited event and ecommerce tracking on every plan regardless of price.
Compared to Fathom Analytics: cheaper Starter plan ($9/mo for 10k pageviews vs Fathom's ~$15/mo), a tracking script reported 54 times smaller than Google Analytics', a free self-hostable community edition (AGPLv3)
Wins:Starter plan costs $9/month for up to 10,000 monthly pageviews, cheaper than Fathom Analytics' roughly $15/month starting price · Tracking script reported to be 54 times smaller than Google Analytics', reducing page-load overhead · Free, self-hostable community edition under AGPLv3, an option Fathom Analytics doesn't offer at any price
Loses:No permanently free tier on hosted cloud plans, only a 30-day trial, matching Fathom's own lack of a free tier · Funnels, custom properties, and the Stats API are locked behind the pricier Business tier · Fathom includes unlimited event and ecommerce tracking on every plan, while Plausible gates some features by tier
Pros
- No cookies or persistent identifiers, avoiding GDPR consent banners.
- Tracking script is dramatically smaller than Google Analytics', reducing page-load impact.
- Fully open-source (AGPLv3) with a free self-hosted community edition.
- Single-page dashboard is faster to read than Google Analytics' multi-report interface.
Cons
- No permanent free tier on the hosted cloud plans, only a 30-day trial.
- Pricing scales with monthly pageviews, so high-traffic sites pay more even for basic reporting.
- Funnels, custom properties, and the Stats API are locked behind the Business tier.
- Reporting depth (e.g., multi-touch attribution, custom audiences) is intentionally simpler than Google Analytics.
Pricing: From $9/mo — $9/month Starter (10k pageviews) vs Fathom Analytics' roughly $15/month starting price (verified undefined NaN, NaN)
