Connect campaign and referral sources to website signup or conversion events.
Track user journeys, retention funnels, product session replays and event analytics using self-hostable PostHog instead of Woopra enterprise plans. DataFast: Source-to-conversion analytics: configure campaign/UTM tags and conversion events yourself. No automatic Stripe, Lemon Squeezy or Polar payment attribution, customer lifetime value, ad-spend reconciliation or complete DataFast parity is claimed. Flowsery: Record and manually inspect browser sessions to investigate user confusion or bugs. Hosted free allowance: 5,000 recordings/month, separate from analytics events. No Flowsery autonomous issue detection, Slack-to-PR fixes or automatic revenue attribution.
Requires event and UTM setup; no complete ad-spend, CRM or multi-touch attribution pipeline. Instrument product events, inspect usage and signup funnels with PostHog hosted Product Analytics. Free: 1 million analytics events/month, one project, unlimited team members and one-year analytics retention. No card, own hosting or paid model API required for this workflow. Collection stops at the free cap without billing; enabling paid usage, more projects or advanced platform features can cost extra. Requires event setup and migration checks; no Amplitude enterprise governance, every integration or full platform parity claimed. Amplitude also has a free plan: this is another workflow option, not proof that switching saves money.
Each comparison covers the workflow described above, rather than every paid feature.
