Signage Sync

Hi guys, I'm sharing something I've been tinkering on for a while: https://signagesync.app/ Like Google Chromecast, but "cast" to multiple screens at once. Create a playlist of auto-refreshing web pages, videos, and even live streams (but not supported on Windows). Also works with local network, e.g. http://192.168.../sales-dashboard It's still early (MVP), but already usable—and I'd love to hear your feedback. Tech stack: SvelteKit, WebSocket, Flutter (desktop)

In plain words

Signage Sync is a tool for displaying content across multiple screens simultaneously, similar to Chromecast but designed for group casting. Users can create playlists of web pages, videos, and live streams that automatically refresh and sync across displays, and it supports local network addresses like internal dashboards. The product works on Mac and Linux, is still in early development, and allows both internet-based and local network content management.

Turn the TVs, tablets and monitors you already own into menu boards, live dashboards and notice screens. Paired by QR in about two minutes, updated in seconds from your phone or laptop. Free to try on 2 screens, no credit card.

Menus and promos in the café, dashboards in the office, notices in the school lobby—pushed from your phone or laptop to every TV you manage. No media boxes. Nothing new to buy. Built for teams without an IT department—the owner, the marketing hire, the admin desk. The first screen usually goes up in an office. The next five go everywhere else. Menus, price boards and this week’s offer go up once from head office and land in every outlet in seconds—no USB stick, no phone call to the branch. If the outlet’s internet drops, the screen keeps playing what it has. When the power comes back, it boots straight into signage. Sales, support queues, sprint goals—any web page, auto-refreshed on a timer…from signagesync.app

  • Term.everything – Run any GUI app in the terminal▲1,094

    I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

    I recreated Windows XP as my portfolio▲1,032

    Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
