I'm a happy Matrix/Element user and was wondering if anyone has written an app specifically for children - something like https://messengerkids.com/ except not by Facebook. Source: 12 months ago

Messenger Kids is really good for this: https://messengerkids.com/ It's made by a gross company, but they have ridiculously tight access controls. - Source: Hacker News / over 2 years ago

Here you go then: https://messengerkids.com/. Source: about 3 years ago

They have linked the unofficial version in their GitHub repo https://github.com/linuxmint/warpinator. Source: about 1 year ago

You can then use Syncthing or Warpinator alongside it to sync them to other devices. Source: over 1 year ago

Other than those you mentioned, there is Warpinator. It works flawlessly for me. You need to create a hotspot manually if there is no internet. Source: over 1 year ago

[Warpinator](https://github.com/linuxmint/warpinator) will do this. I've used it in the past and I just double checked if it will send android to android, which it does. There are packages for Windows and in F-Droid. It is developed by the Linux Mint team, so seems like a trusty source. But, always double check if you are confident in the publisher.

I use Warpinator. It is developed by Linux Mint but I have ports installed on Windows, Android and even iPad. Source: over 1 year ago
