# About this site This site is published by Presso Network Ltd, which also builds an events platform. It is a reference for a category, written so that it can be used by people with no relationship to the publisher, including to assess competing products. ## The conflict of interest, stated plainly The publisher of this site sells an event platform, and that platform appears on the implementations page. That is a conflict of interest. Rather than pretend otherwise, the site is built so the conflict is checkable: - The criteria are published in full, each with a stated test and a stated failure condition, before any platform is assessed against them. - The implementations table is ordered alphabetically, carries no ranking and no overall verdict, and records where the publisher's own product fails a criterion. - Where a criterion cannot be verified from public information, it is recorded as unknown rather than assumed, for every platform equally. - The site carries no advertising, no affiliate links, and no sponsored placements. No platform can pay to appear, to be assessed differently, or to be removed. ## Editorial policy Assessments are based on publicly checkable evidence: vendor documentation, app store listings, help centres and changelogs. Every verdict on the implementations page cites a source and the date it was checked. Marketing copy is not evidence. A vendor describing its product as “app-free” does not establish that it meets criterion one; an app store listing showing a required download establishes that it does not. The criteria themselves change rarely and never quietly. Changes are dated, and the previous wording is kept, because a definition that can be revised without trace cannot be cited. ## Corrections If an assessment here is wrong, it should be corrected, and that includes assessments that are wrong in the publisher's favour. If you build or use a platform listed here and a verdict does not match reality, send the evidence that settles it: a link, a screenshot, a documentation page. Corrections that come with evidence are applied and dated. The same applies to the criteria. If one is ambiguous, unverifiable in practice, or written in a way that happens to favour a particular implementation, that is a defect in the criteria and worth reporting as one.
