Primary sources first
Product facts come from current vendor websites, documentation, pricing pages, help centers, and release notes. We link the most important sources on every profile.
Here is how we decide what belongs, how we verify it, and how publishing by Diffie affects the directory.
Product facts come from current vendor websites, documentation, pricing pages, help centers, and release notes. We link the most important sources on every profile.
A documentation review is not a hands-on benchmark. We do not claim to have run a tool unless the page explicitly describes the test, environment, and date.
Capabilities, public prices, and documented integrations are facts. Best-fit teams, strengths, and limitations are editorial assessments based on those facts.
The searchable directory is alphabetical. Guide order reflects each page’s focus and is not sold to vendors. Sponsored placements are visually and semantically labeled.
We include products that use AI materially in software QA or provide infrastructure and workflows buyers routinely compare with AI-native testing agents. A product must have enough current public information to write a useful, sourced profile.
Diffie owns and funds this directory. Diffie is also one of the products listed and advertises on the site. That conflict is disclosed in the header context, footer, ads, Diffie cards, and the Diffie profile.
We do not describe the site as an independent lab, do not sell ranking positions, and do not hide sponsored links. The purpose of including alternatives and limitations is to make the site valuable even when Diffie is not the right product for a visitor.
Software changes quickly. Send a source URL and the exact correction to [email protected]. We prioritize corrections to pricing, availability, product scope, beta status, and security-relevant claims.
