summary: >-
  FreeTTS documents exactly one embeddable client-side component - a drop-in
  read-aloud widget delivered by a single script tag. It is fully specified on
  the developer page, and the script it names is not served.
families:
- name: Embed widget
  kind: script-tag web component
  loader: https://freetts.org/widget.js
  loader_status: 404
  loader_probe: >-
    GET https://freetts.org/widget.js returned HTTP 404 with the Next.js
    catch-all HTML body (67,991 bytes), both plain and with a
    Referer: https://freetts.org/developers header. There is no versioned or
    CDN-hosted alternative - cdn.freetts.org also returns 404, though it is
    allowlisted in the site's own media-src CSP.

  kind: hosted first-party surface
  url: https://freetts.org/studio
  status: live
  embeddable: false
  note: >-
    A hosted projects-and-timeline editor (PRO). Not embeddable and not a
    component library; recorded so the component inventory is not mistaken for
    the whole client-side surface.
- name: Browser extensions
  kind: end-user client
  note: >-
    Chrome, Edge and Firefox extensions are the provider's real client-side
    distribution. They are catalogued in packages/freetts-packages.yml rather
    than here, because they are applications rather than components a developer
    embeds.
findings:
- >-
  The single embeddable component FreeTTS documents cannot be used: the loader
  URL published in a copy-paste snippet on the developer page 404s. This is the
  cheapest fix in this profile and the most visible failure - anyone following
  the documentation gets a silent no-op on their page.
