QuestionDataFastPostHog
Revenue attribution as the default workflow
Built around payments, subscriptions, channels, campaigns, and visitor journeys.
PostHog can help, but revenue usually depends on extra setup, events, or reports.

Stripe, Shopify, WooCommerce, Polar, Lemon Squeezy, Payment Links, and API support.
PostHog usually needs custom events, ecommerce setup, or manual data mapping.
Ad spend to revenue
Meta Ads spend, attributed revenue, and ROAS are shown in the dashboard.
PostHog is less focused on spend-to-revenue reporting for founders.
Visitor journeys tied to revenue
See what visitors did before goals, payments, renewals, and churn.
PostHog is strong for behavioral journeys, but revenue still needs event design.
Privacy-friendly option
Default tracking is optimized for attribution; a cookieless script is available when needed.
PostHog is not primarily a privacy-first analytics tool.
Small founder setup
Made for small teams that need useful revenue answers without a data analyst.

I've using DataFast for the past month.

Practical difference

The real question is not pageviews. It is revenue.

A normal analytics comparison starts with traffic reports: visitors, sessions, referrers, devices, countries, and pages. Those reports are useful, but they do not tell a founder where to spend the next hour or the next dollar.

PostHog is a good choice when its main strengths match your needs. Choose PostHog when you need product analytics, session replay, feature flags, experiments, and deeper in-app behavior analysis. But if you are running a small SaaS, ecommerce store, paid newsletter, course, or online business, you eventually need to connect analytics to money.

DataFast is opinionated around that job. It helps you connect traffic sources, landing pages, goals, payments, subscriptions, ad spend, and visitor journeys so you can see which acquisition work is actually growing the business.

1. Track the visit

DataFast starts with lightweight website analytics: pages, referrers, countries, devices, UTM campaigns, goals, and segments.

2. Connect the money

Connect Stripe, Shopify, WooCommerce, Polar, Lemon Squeezy, Payment Links, or the Payment API so revenue can be attributed to visitors.

3. Compare with PostHog

PostHog may still be useful for its strengths, but DataFast makes the revenue workflow easier to inspect from day one.

Feature comparison

DataFast is intentionally narrower: it is built to show where revenue comes from.

Revenue attribution matters because pageviews do not pay bills. The useful question is which page, source, campaign, country, device, or visitor journey led to money. DataFast keeps that question visible.
