Alternatives to Fiddler
Other LLM tooling and evaluation vendors we measure, sorted by how much they publish that Fiddler does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 27 that differ from Fiddler on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Fiddler has 7 gaps in what we could measure: Subprocessor list, Data location stated, Status page with history, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Named privacy contact. The column “publishes and Fiddler 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.
