## Which should you choose?

Pick Piqo if A founder who wants each payment from a connected processor — Stripe, Paddle, Polar, Lemon Squeezy, Creem or Dodo Payments — credited to the visit that brought it, with AI crawlers counted from the server and up to 20 sites on every plan.

Pick Seline if 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: Piqo — You need a settled price or privacy position. Piqo's pricing page, terms, privacy policy and data-processing page disagree on plan prices, on whether a cookie is set by default and on whether data sits in Germany or Singapore, and the record shows each conflict rather than choosing between them.

Consider something else: Seline — 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.

## Documented by only one

One side documents these and the other does not. An absence is a missing source, not a stated "no" — except where a line says the other page was READ on a date and does not mention it, which is a sourced observation and the only one-sided case this site leans on.

- Entry paid plan: Seline: From $9 a month, billed monthly, at 10,000 events a month on a single Pro plan that carries every feature.
- Pricing model: Seline: One Pro plan with every feature, priced by monthly events: pageviews and custom events share one limit, from 10,000 events at $9 to 20,000,000 at $649 a month, billed monthly or yearly (yearly gives two months free). Above 20,000,000 events the page says to contact them.
- Works without cookies: Seline: Supported — A cookie-based tracking mode exists as an optional setting and is off by default
- GDPR / data residency: Seline: Seline is legally based in Poland, and its application servers and databases run on Hetzner in Germany; sub-processors listed are Hetzner, Stripe and Postmark.
