    These are SarnAI's own statements, read from its pages. We did not audit them. A line that is missing was not found on the pages we read; it does not mean the practice is absent.

    Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.

    How we read a tool

    No votes, no reviews, no vendor claims. Every week a crawler reads each tool's own site and a few public registries, and the words on the card are bands over what it read.

    • Use: visits to the site (estimated), installs from npm and PyPI, presence in Chrome's usage report.
    • Activity: the newest release on GitHub, npm or PyPI; the newest dated page on the site; open roles on a public jobs board.
    • Price: the vendor's own pricing page, read with the date. A figure is printed only when it is on that page.
    • The line and the use cases are written by us from the homepage, one tool at a time, and refused when they repeat the vendor's marketing.

    How AI assistants read each site — the reading vendors ask us about — is on each tool's own visibility page.
