    "Google Messages for web" alternative

    Project mention: Show HN: Google Messages for Web" Alternative | news.ycombinator.com | 2025-01-20

    I made an open-source alternative to "Google Messages for web" that utilizes WebRTC data channels to show your phone's text messages in browser.

    It's an Android app you can install on your phone, with a server that uses Socket.io for signaling and coturn for the TURN server. You can also self-host it if you prefer. All source code is in the repository.
