# Seline Canonical: https://inetgeek.com/analytics/seline/ Cookieless web analytics that credits each Stripe or Polar payment to the visit behind it, priced by monthly events on one plan, with visitor journeys, funnels and profiles, hosted in Germany. ## Who it suits A founder who wants Stripe or Polar payments credited to the visit behind them, alongside visitor journeys, funnels and profiles, on one plan priced by monthly events, from $9 a month for 10,000 events, with data hosted in Germany. Consider something else if You need a free plan or a self-hosted option: Seline offers only a 7-day trial with no card, is hosted only, and states no SOC 2 or similar audit. Its direct revenue connections are Stripe and Polar; any other processor has to send revenue as custom events from your own code. ## iScore 62 / 100 (80% interval 55–69), rank 5 of 12 in analytics — interval overlaps the next rank, so this is an ordering, not a finding. inetGeek's own reading, computed from sourced facts against category peers by disclosed rules. Not a provider claim. Intervals are 80%; a provider with few documented facts is pulled toward the category middle rather than scored on what little is known. Read this score with care: - Capacity and limits is thin: 0 of 2 criteria are scored, so it sits near the category middle with a wide interval (40–62). Read the interval, not the point. - Documented but not scored, because the page states it as text with no comparable number or a yes/limited/no (a one-time, usage-based or other-vendor price, or a per-site choice): retention_window, sites_included. Read them on the provider page; the score neither rewards nor penalises what it could not compare. Method: https://inetgeek.com/iscore/.
