DataFast is a revenue-first analytics tool for founders — its whole job is connecting traffic to paying customers, and it does that well, cookielessly. Kymo shares the cookieless, no-banner foundation and Stripe revenue attribution, then adds a second lens DataFast does not have: AI-crawler visibility, showing which AI systems read your pages and what prompts those pages likely answer. If revenue attribution is your single focus, DataFast is sharp. If you also want to see the machines, that is Kymo’s wedge.

What you get with Kymo that DataFast doesn’t offer
AI-crawler visibility DataFast does not track
DataFast follows humans to revenue. Kymo also watches the AI crawlers reading your pages — GPTBot, ClaudeBot, PerplexityBot — classified as answering, indexing, or training.
The AI Visibility Report
Kymo infers the prompts your top pages likely answer and writes a weekly report with actions — a view DataFast, being revenue-focused, does not offer.
A per-visitor real-time map
Kymo pins each active visitor on a world map as they arrive, numbered — a live geographic view alongside the revenue numbers.
AI tracking is always free
Kymo meters only human events; the AI-crawler layer never counts against your limit, so watching the machines costs nothing extra.
When to choose DataFast
Choose DataFast if revenue attribution is the one job you need done — it is built end to end around connecting traffic to paying customers, has iOS and Android apps, and comes from a maker with deep indie-founder focus. If “which marketing brings paying customers” is your only question, DataFast answers it directly. Kymo is the better fit when you want that revenue view and AI-crawler visibility on the same cookieless dashboard.
Kymo vs DataFast: common questions
Is Kymo a good DataFast alternative?
Yes, especially if you want AI visibility alongside revenue tracking. Both are cookieless and attribute Stripe revenue to a source. Kymo adds AI-crawler visibility and an AI Visibility Report; DataFast is more single-mindedly focused on revenue attribution and ships mobile apps.
Does DataFast track AI or ChatGPT traffic?
DataFast can attribute a human visit that arrived from an AI site to revenue, but it does not classify AI crawlers or infer the prompts your pages answer. Kymo tracks the AI-referred human and the AI crawler that read the page.
Is Kymo cheaper than DataFast?
They start at the same price — $9/mo for 10,000 events — so cost is a wash at the entry tier. Kymo additionally never counts AI-crawler tracking against that event limit.
Is Kymo GDPR compliant without a cookie banner?
Yes. Like DataFast, 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 do revenue attribution like DataFast?
Yes. Kymo ties Stripe conversions to the page and first-touch source that earned them. DataFast goes deeper on revenue-specific reporting and mobile apps; Kymo balances revenue with AI visibility.
