Plausible tells you how many visitors came from each source. DataFast tells you how much money came from each source. When you connect Stripe, every payment is automatically attributed to the traffic source, campaign, and landing page that brought the customer. You stop guessing which marketing channels are profitable and start knowing.
DataFast calculates revenue per visitor automatically for every traffic source. You can instantly see that visitors from a specific Twitter campaign generate $2.40 each while Reddit visitors generate $0.15. Plausible shows pageviews and bounce rates, but has no concept of visitor value. This single metric changes how you allocate your marketing budget.
DataFast offers a free tier with 5,000 events/month so you can test revenue tracking before committing. Plausible requires a paid plan from day one with a 30-day trial. DataFast paid plans start at $5/month and include revenue attribution at every tier, while Plausible starts at $9/month and focuses solely on traffic analytics regardless of plan.
DataFast has a similarly lightweight, cookie-free tracker and a simpler early-stage revenue attribution workflow. Plausible is the more mature traffic analytics product; choose DataFast when revenue per source is the deciding metric.
Replace the Plausible script tag with the DataFast tag, then report completed payments through the revenue API. Historical traffic data stays in Plausible.
DataFast attributes dollar amounts you report through its authenticated revenue API to traffic sources, campaigns, and pages. You see revenue rather than only conversion counts.
