DataFast review
Connects website traffic to payment revenue with first-touch and campaign attribution.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
DataFast connects website visits with completed payments, giving founders and online businesses a way to see which traffic sources, campaigns, referrals, and landing pages contribute revenue. Its real-time dashboard reports visitors, pageviews, sources, conversions, and revenue. First-touch attribution uses first-party visitor tracking, while a revenue API can send authenticated payment events. This focus makes DataFast a fit for lean teams tracking traffic-to-revenue attribution, rather than teams seeking a broad behavioral analytics suite.
Attribution is the product’s central strength. Campaign ROI tracking covers UTM campaigns and referral sources, and revenue events can use order IDs to avoid duplicate event handling. The tracking script is under 1 KB gzipped. Stripe, LemonSqueezy, and Paddle are listed integrations; the API and self-hosted options offer additional ways to connect payment data or run the open-source tracker and stack. These capabilities suit businesses that want to connect marketing activity to payment outcomes without centering their workflow on extensive on-site behavior analysis.
The Free plan costs $0 forever and includes 5,000 events per month, one website, seven days of data retention, core analytics, and Revenue API attribution. Founder costs $5 per month and raises the allowance to 10,000 events per month for one website, extends retention to three years, and adds revenue attribution, revenue per source and campaign, and email support. Choose DataFast if revenue attribution is the main need and its event allowance fits; look elsewhere if verified funnel analysis or session replay is essential.
