These are on the roadmap. Each gets a page when it actually works — no placeholder pages in the meantime.

  • Business Name Generator
  • Company Slogan Generator
  • SVG Generator
Not possible in a browser (1)

These are in the catalogue but cannot be built here without a backend, a paid service or a page that fails on the file it names. The reason is recorded next to each rather than left as silence.

  • Data Matrix Generator

    Encoding Data Matrix needs a Reed-Solomon error-correction implementation and the format's placement algorithm, neither of which is in any library already bundled here.

    The QR code generator's library does not cover it, and writing an encoder from the specification is a poor trade against the number of people who need one. The scanner reads Data Matrix, because the browser's own decoder covers it.
