VisitTrack vs DataFast

What's the difference between DataFast and VisitTrack?

Both products answer the same question — which referrer, campaign and landing page brought the people who paid — and both are hosted, script-tag tools aimed at indie founders. Both have funnels, goals, visitor journeys, a live globe, Search Console keywords, public dashboards, a REST API, a CLI, an MCP server and AI crawler tracking. If you only compared the homepages, you could easily think they're the same product.

The differences are in three places. Behavior: VisitTrack includes session replays and click heatmaps, so from a paying visitor's profile you can watch the session that converted; DataFast has neither. Limits: DataFast's Starter plan is one site and one seat, while VisitTrack has no site or seat limits on any plan. Breadth of revenue: DataFast integrates with more payment platforms and computes subscription metrics like MRR, LTV and churn; VisitTrack focuses on attribution — revenue by channel, revenue per visitor, and how many days and visits each customer took to convert.

How does revenue attribution work in DataFast vs VisitTrack?

DataFast connects to your payment provider with an API key (a restricted key for Stripe), creates webhooks where possible and backfills existing payments. To tie a payment to a visitor, you pass DataFast's visitor and session cookies as checkout metadata, let its script detect a checkout id on your success page, or call datafast("payment", { email }).

VisitTrack uses the provider's webhook, verified against its signing secret. You pass VisitTrack's anonymous visitor id at checkout — client_reference_id for Stripe, a custom-data field for Polar, Lemon Squeezy, Paddle and Razorpay — and each payment inherits that visitor's first touch: first referrer, first UTM source, medium and campaign, and first landing page. Refunds (including partial ones) are subtracted automatically, retried deliveries are deduplicated, and each payment also writes a payment_completed event you can use as the last step of a funnel. See revenue attribution.

One practical difference: VisitTrack documents its model as first-touch, while DataFast's docs describe support for long-term and multi-touch journeys without naming a crediting model. If you need to explain your numbers to a co-founder or investor, check that each tool's model matches how you think about acquisition.

Cookies, consent banners and where your data lives

Neither tool is cookie-free by default. DataFast's standard script sets first-party cookies for the visitor and session (its docs say you may need a cookie banner), and its cookieless script, launched in April 2026, uses a daily-rotating server-side hash instead. VisitTrack's standard mode keeps an anonymous first-party id, and its cookieless mode stores nothing on the device, also with a daily-rotating hash.

Both vendors are candid that cookieless tracking weakens long-range attribution, because a visitor returning after 24 hours looks new. VisitTrack offers two ways around it: hybrid mode, which is cookieless only for visitors in the EU/EEA, UK and Switzerland and keeps a first-party id everywhere else, and a first-touch hand-off where your own signup form keeps the original source and sends it back with the signup.

On data location, DataFast's DPA says most of its infrastructure is outside the EU, including in the United States, with transfers covered by subprocessors' SCCs. VisitTrack stores analytics in its own PostgreSQL databases on EU infrastructure. For EU founders, that can shorten the privacy-policy conversation.

Where DataFast is stronger

• More payment integrations: Shopify, WooCommerce and Dodo Payments natively, plus a Payments API for anything else. VisitTrack supports Stripe, Polar, Lemon Squeezy, Paddle and Razorpay.
• Subscription metrics: MRR, LTV, churn, and goals that fire automatically on trial start, upgrade, downgrade and cancellation.
• Paid ads: Meta Ads spend and ROAS next to attributed revenue.
• Mobile: native iOS and Android apps for the dashboard, and a React Native/Expo SDK for web-to-app funnels.
• Migration: a built-in Plausible importer. VisitTrack's import API takes any tool's data, but you convert it to NDJSON yourself.
• Social mentions: X and Reddit mentions on Growth. VisitTrack's mentions cover Hacker News.

Where VisitTrack is stronger

• Session replays and click heatmaps included, sampled and with every input masked — no second tool to install next to your analytics.
• Unlimited websites and team members on every plan, with per-site access for teammates. DataFast's Starter plan is 1 site and 1 seat.
• EU infrastructure, plus a hybrid mode that applies cookieless tracking only where ePrivacy consent rules bite.
• Bot filtering that scores every visit at ingest and again when it ends, shows you the reason each bot was flagged, and never bills you for bots. AI crawler tracking has no separate request cap.
• Razorpay support for founders selling in India.
• A lower entry price — $5/month for 10k events versus $9 — and a lifetime deal.
