Alternatives to Obsidian
Other Knowledge base and wiki vendors we measure, sorted by how much they publish that Obsidian does not. This is a comparison of disclosure, not of features or fitness.
12 shown of 26 that differ from Obsidian on at least one criterion we measured for both. Public transparency score, not a product or security rating.
Obsidian has 8 gaps in what we could measure: Data processing agreement, Subprocessor list, Status page with history, Certifications named, Uptime SLA with a figure, security.txt (RFC 9116), Notice before subprocessors change, Named privacy contact. The column “publishes and Obsidian 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.
