Alternatives to Constructor
Other Search and vector infrastructure vendors we measure, sorted by how much they publish that Constructor does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 25 that differ from Constructor on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Constructor has 8 gaps in what we could measure: Subprocessor list, Status page with history, Public pricing, Certifications named, Uptime SLA with a figure, No third-party tracking before consent, security.txt (RFC 9116), Notice before subprocessors change. The column “publishes and Constructor 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.
