  First-party client distribution for the Safari developer surface. Apple ships almost
  nothing for Safari through a public package registry: the browser-facing APIs
  (Web Extensions, WebKit, SafariServices, Web Push, WebAuthn, Payment Request) are
  platform APIs already present in Safari, and the developer tooling is bundled inside
  Safari, Safari Technology Preview and Xcode rather than published to npm, PyPI or
  Homebrew. The one first-party JavaScript library Apple distributes for the web is the
  Apple Pay SDK, served unversioned from Apple's own CDN.

      Apple Pay SDK for the web. Loaded with a script tag; defines the

      Unpinned CDN distribution — checked 2026-09-07, nothing to record. Apple's own
      documentation instructs developers to load the path `1.latest`, which floats to
      whatever build Apple is currently serving; the file exposes no version string.
      A second path, /jsapi/v1/apple-pay-sdk.js, is also live and serves a DIFFERENT
      build (166,040 bytes vs 58,017 bytes at 1.latest, different MD5). There is no
      registry metadata endpoint and no pinned URL, so a consumer cannot tell which
      build they are getting either. Probed 2026-09-07: both paths HTTP 200,
      ETag "7350162cd6fa296bb88c2b8054982c36" on 1.latest.

    description: >-
      W3C WebDriver driver for Safari, and — with the --mcp flag added in Safari 27
      beta / Safari Technology Preview 247 — the Safari MCP server. Bundled with the
      operating system and with Safari Technology Preview.
    note: >-
      Checked 2026-09-07, nothing to record. Ships inside Safari; there is no registry
      release and no independent version number — its version tracks the installed
      Safari build. The npm package literally named `safaridriver` (latest 1.0.1,
      published 2025-12-30) is webdriverio-community/node-safaridriver, a THIRD-PARTY
      wrapper, and is deliberately not listed here as an Apple package.

    description: >-
      Xcode command-line tool that converts a Chrome/Firefox web extension into a Safari
      web extension Xcode project.
    note: >-
      Checked 2026-09-07, nothing to record. Distributed inside Xcode and invoked
      through xcrun; no public registry entry exists, and its version tracks the
      installed Xcode.
