Fathom is a polished, established privacy-analytics product with a lovely interface and bundled uptime monitoring. Kymo matches its cookieless, no-banner foundation and adds the thing Fathom does not do: AI-crawler visibility — logging which AI systems read your pages and inferring the prompts those pages answer. If you want refined, simple human analytics, Fathom is a safe pick. If AI visibility is the reason you’re looking, Kymo is built around it.

What you get with Kymo that Fathom doesn’t offer
It watches the AI crawlers Fathom ignores
Fathom filters bot traffic out of your stats. Kymo classifies AI crawlers instead — answering vs. indexing vs. training — and shows the pages ChatGPT, Claude, and Perplexity fetch most.
An AI Visibility Report with actions
Beyond a crawler log, Kymo infers the prompts your top pages likely answer and writes a weekly report you can act on. Fathom has no comparable view.
Stripe revenue attribution built in
Kymo ties Stripe conversions to the page and first-touch source that earned them, including AI-referred traffic — deeper than Fathom’s event tracking.
Lower entry price
Kymo starts at $9/mo against Fathom’s $14/mo, and never counts AI-crawler traffic against your event limit.
When to choose Fathom
Choose Fathom if you want a mature, beautifully finished privacy-analytics product, value its bundled uptime monitoring, or prefer its long 30-day no-card trial and established brand. Fathom is a strong, trustworthy tool and its polish is real. Kymo is the better fit when you specifically want AI-crawler visibility and Stripe-level revenue attribution alongside the basics.
Kymo vs Fathom: common questions
Is Kymo a good Fathom alternative?
Yes. Both are cookieless and need no consent banner, so the core privacy analytics feel similar. Kymo adds AI-crawler visibility, an AI Visibility Report, and Stripe revenue attribution; Fathom adds bundled uptime monitoring and a longer trial. Choose on those extras.
Does Fathom track AI or ChatGPT traffic?
Fathom can show a human visit that arrived from an AI site as a referrer, but it filters out crawlers and does not classify AI bots or infer prompts. Kymo tracks the AI-referred human and the AI crawler that read the page.
Is Kymo cheaper than Fathom?
Yes, at the entry level. Kymo starts at $9/mo while Fathom starts at $14/mo, and Kymo never counts AI-crawler tracking against your event limit. Fathom offers a longer 30-day trial with no card.
Is Kymo GDPR compliant without a cookie banner?
Yes. Like Fathom, Kymo is cookieless, stores no raw IPs or user agents, and is designed to run without a consent banner. You remain responsible for your own privacy disclosures.
Does Kymo include uptime monitoring like Fathom?
No. Uptime monitoring is a Fathom extra that Kymo does not bundle. Kymo focuses on analytics and AI visibility rather than site-status monitoring.
