Three doors

    Learn
    Six short chapters: what it is, how diffing works, why screenshots flake, baselines and approval, CI, and how to choose a tool.
    Compare the tools
    Runner integrations, hosted review services, diff engines and mobile tools in one table, every claim sourced from the vendor's own docs.
    The manifest
    One JSON file per run that lists every comparison. Built upon CTRF, written by several tools, read by PR bots and review apps.
