Alternatives to Marvin
Other User research and testing vendors we measure, sorted by how much they publish that Marvin does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 23 that differ from Marvin on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Marvin has 10 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Status page with history, Public pricing, Uptime SLA with a figure, HTTPS enforced with HSTS, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change. The column “publishes and Marvin 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.
