Consider something else if…

  • Cool Analytics: You need a product you can sign up to today: Cool Analytics shows a waitlist and says early access is opening soon, offers a 7-day trial with a card on file, is hosted only, and does not state a SOC 2 or similar audit.
  • 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.

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.
