Show HN: Bigwords.page – Turn any screen into a sign. The URL is the app

Bigwords.page is a tiny web app that turns any browser into a full‑screen sign by encoding the entire message and settings in the URL fragment. You create a display by putting text after the # and adding options with &key=value; spaces become %20, %0A makes new lines and || splits slides. Text auto‑scales to fill phones, tablets, laptops or TVs, and the editor and docs run in the browser (displays require JavaScript). No account, no server storage and the fragment never leaves the browser, so messages are private by design. The project is open source under MIT and fonts are bundled under separate open licenses.

Features include Markdown styling, animated effects, scrolling tickers, slides with adjustable intervals, countdowns using {countdown} with &timer or &until and custom zero messages, QR codes and embedded images (including data URIs), and visual options like bg, fg, font, size‑max, anim and cdfmt. Examples shown: arrival signs, “on air” lights, exam timers, café Wi‑Fi cards with QR, New Year countdowns, and news tickers. The URL-as-display model makes it easy to share, bookmark or put a link on a TV or phone without installing anything. Documentation and an in‑browser editor explain the URL syntax and available parameters.
