Transparency alternatives to Slido
Other Event management vendors we measure, sorted by how much they publish that Slido does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 47 that differ from Slido on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Slido has 6 gaps in what we could measure: Data processing agreement, Subprocessor list, Uptime SLA with a figure, No third-party tracking before consent, Notice before subprocessors change, Named privacy contact. The column “publishes and Slido does not” is the one that closes them.

Only criteria we could measure for both are counted. Where we could measure one and not the other, the row is silent: that would be a statement about our measurement, not about either vendor. Every single result with its source is on the two profiles.
