The short answer

Consider something else if…

  • 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.
  • 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.

Only criteria both providers publish appear here; a tinted cell marks a real difference. Criteria only one of them documents are listed below, and an absence there means we found no source — not that the feature is missing. How we source this.

The small bar above a value is inetGeek's own lean toward that side — computed from the same facts shown, never a number the provider published. See the picker below "The short answer" to weigh only the criteria you care about.

Documented by only one.

These criteria are published by one provider and not the other. An absence here means we have not found a source, not that the feature is missing — except where we say we read the other provider's own page on a given date and it does not state it. Those rows lean, and the provider can correct them with a link.
