Turn any web browser into a full-screen sign using just a URL

You can turn any spare phone, tablet, or smart TV into a digital sign without installing an app or making an account.

Bigwords.page gained traction on Hacker News this week, drawing 364 points and 112 comments. The web tool lets you build auto-resizing text displays, countdowns, slides, and QR codes directly in your browser. Here's the gist: the full display setup is saved inside the URL link itself.

Why it matters: You do not need dedicated signage software or a server backend to display a Wi-Fi password or an event countdown. Because web browsers never send URL fragments to a server, your sign stays entirely private, works offline once loaded, and runs on any device with a browser.

Know this: It supports Markdown text, slide transitions marked with ||, date countdowns, and browser-generated QR codes for Wi-Fi logins or contact info without calling third-party services.

Your old, dusty tablet just found its new day job.
