How these pages are written
- Every price, limit and retention window is what the other service’s own public pages said on the date printed at the top of the page. Nothing comes from a review site, and nothing is guessed: a cell that could not be verified says so.
- Every page has a section on where the other service is the better choice, written to be useful rather than polite.
- A fact that has gone stale is a one-line fix. Send the page that says otherwise through the contact details on this site, and the cell will be corrected with the date moved.
Prefer a method to a verdict? The comparison page names nobody and gives you six questions with the command that answers each one; the API comparison puts nine services in one table.
