Transparency alternatives to VWO
Other Feature flags and experimentation vendors we measure, sorted by how much they publish that VWO does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 28 that differ from VWO on at least one criterion we measured for both. Public transparency score, not a product or security rating.
VWO has 4 gaps in what we could measure: Status page with history, Public pricing, Uptime SLA with a figure, No third-party tracking before consent. The column “publishes and VWO 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.
