Transparency alternatives to Optimizely
Other Feature flags and experimentation vendors we measure, sorted by how much we found at them and not at Optimizely. This is a comparison of disclosure, not of features or fitness.
12 shown of 28 that differ from Optimizely on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Optimizely has 8 gaps in what we could measure: Data processing agreement, Subprocessor list, Data location stated, Public pricing, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change. The column “Found there, not found at Optimizely” 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.
