Comparison
DataSaaS vs PostHog
PostHog tells you what users do inside your app. DataSaaS tells you which channels bring users who pay.
PostHog is an all-in-one product analytics suite — session replay, feature flags, A/B testing, surveys, and product funnels. It is excellent for post-signup product optimization, especially for engineering teams who want one platform for everything. But PostHog was not designed for traffic-to-revenue attribution. Its 80KB+ script bundle is overkill for marketing sites and landing pages, it has no native Stripe integration, and it cannot calculate Revenue Per Visitor by traffic source. DataSaaS is purpose-built for the acquisition funnel: a 4.8KB script, native payment provider integration, and a dashboard that answers the one question founders care about most — which marketing channels bring paying customers.
DataSaaS revenue dashboard with a 4.8KB script footprint showing traffic-to-revenue attribution — 16x lighter than PostHog's 80KB+ bundle

Frequently asked questions
Can DataSaaS replace PostHog?
They solve different problems. DataSaaS replaces PostHog for traffic attribution and revenue analytics — knowing which channels bring paying customers. If you also need session replay, feature flags, A/B testing, or post-signup product analytics, keep PostHog for that. Many teams use DataSaaS for acquisition and PostHog for product.
Why is PostHog's script so much larger?
PostHog bundles session replay, autocapture, feature flag evaluation, and survey rendering into its script — features that require significant client-side code. DataSaaS tracks pageviews, sessions, and custom events with a purpose-built 4.8KB script that has zero dependencies. For marketing sites and landing pages where page speed matters, the difference is significant.
Does PostHog have revenue tracking?
PostHog can ingest custom events tagged with revenue data, but it has no native Stripe, LemonSqueezy, or Polar integration. You would need to manually instrument payment events and build custom reports. DataSaaS connects to your payment provider in minutes and attributes revenue to traffic sources automatically.
Can I use both DataSaaS and PostHog?
Yes. Many teams run DataSaaS for traffic-to-revenue attribution on their marketing site and PostHog for product analytics inside their app. The DataSaaS script is lightweight enough to coexist with PostHog without affecting page performance.
