About DataFast

DataFast is a hosted web analytics tool from indie maker Marc Lou that ties traffic to revenue. Alongside the usual visitors, pages, referrers, countries and devices, it connects to payment providers such as Stripe and LemonSqueezy so you can see which channels, campaigns, pages and even social posts bring paying customers, not just visits. It also tracks AI chatbot referrals and bot requests, goals and custom events, offers an API, CLI and MCP server, and shows real-time visitors on a globe. It is popular with indie hackers and small SaaS founders who mainly want to know where revenue comes from. Plans are priced by monthly events with a 14-day free trial and no card required; there is no free plan or self-hosted version. The trade-offs are a young product run by a very small team, a feature set geared to startups rather than larger marketing teams, and data held on its servers. It runs in the browser.

Best for: Indie founders and small SaaS teams tracing revenue to marketing channels.
