Show HN: High Definition Calling and File Sharing Without the Internet

Trango is a cross platform, calling and file sharing solution which works on LAN and the wider internet. Your data never leaves your local Wifi. The internet is only used to discover those on the same network as you.

We were in the same office and needed a fast, simple way to communicate with eachother without coming in close contact (covid 19) and wanted to do that over LAN rather than use tools over the internet NOR use our ancient intercom system. So now we are using this internally for fast file sharing and good quality video calls.

It is open source and a self hosted version is available here https://github.com/trango-io/trango-self-hosted. Native Windows, Mac, iOS and Android applications are in the works right now and should be ready sometime at the end of this month.

We have been talking to quite a few of you as to how you would like to use trango. Many of you would like to use it in offices, factories, hotels and even homes.

Some very interesting use cases have been built about how trango can be used off-grid, connecting remote communities to eachother over W(LAN). If you guys are interested, please join the trango community on reddit and suggest as to how/where you would like to see trango going:
