We created trango, a (W)LAN based audio/video calling and file sharing solution. Ideal for talking to colleagues, family and friends in any shared space. Can be used by offices, hotels, factories, off-grid establishments and any shared space. It is free, open source and cross platform. A self hosted version is also available for Linux and Windows machines/servers. With self-host, you completely bypass the internet which can be found at https://github.com/trango-io/trango-self-hosted. The web version only uses the internet to discover those on the same network as you. In either case, your data never leaves your own network. We have even encrypted it for further security. Group calls and online calls are being added as we speak.
We are working on an Android and iOS mobile app along with desktop apps for more convenience. We are also enhancing the functionality of the self-hosted version so that it can work on an enterprise level with a slew of admin and security features. The program is still in beta so please bear with us.
Background: We started using trango in our factory of 100 or so people since the internet connectivity wasn’t great. Also, due to Covid, we were shunning meetings and reluctant to meet eachother in person. Other establishments around us liked the idea of communicating over LAN so we deployed trango for them and now they too are using trango instead of their local landlines (intercom/pbx). Trango is very simple to set up and we would like to keep it that way. On the client side, trango is also easy to use due to its visual nature. The goal is to create an instant messaging solution which works online and offline seamlessly.
We would love your feedback on trango. If anyone of you wish to contribute to open-source, you are most welcome. You can also subscribe on our webapp https://web.trango.io to keep yourself updated to our full launch and other feature additions.
Thanking you,
