24 alternatives to 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)

    Good to be back on HN with all-new CoScreen, a little more than 3 years after it launched over here! With CoScreen 5.0, you can now share your windows from multiple displays at the same time, a long standing request by our most avid users and impossible in other apps. It also has a lightning-fast, Rust-based window compositing, scaling, and streaming engine now. CoScreen was always meant to be different so that you and your team can share your screens simultaneously and multi-directionally, and to be able to control what is being shared. We saw it as a natural extension and closely coupled…

    Two browser windows (acting as socket clients) communicate their: - Screen dimensions - (screen.width, screen.height) - Window dimensions - (window.innerWidth, window.innerHeight) - Window X/Y position - (window.screenX, window.screenY) ...or whichever calculation works best for you. The original work by Bjorn Staal https://twitter.com/_nonfigurativ_/status/172732259457002734 used localStorage, but I found sockets more fun, because if tweaked a bit, this can be shared with friends. Here's a demo of how it works and the codebase:…

    Hey HN, I want to share with you something I and my four colleagues have been working on for the last several years. It’s a whiteboarding and notes tool called Muse[1]. We just released a 2.0 version which includes local-first sync. A little backstory: I’m one of the authors of the 2019 essay Local-first software[2]. (Past HN discussions[3][4].) The thesis is to reclaim some of the ownership over our data that we’ve lost in the transition from filesystems to cloud/SaaS. So I’m excited to bring CRDT technology “out of the lab” and into a commercial product as a chance to prove the value…
