I am the only one in our office using Linux, while everything is working great except the team-communication.
I just need to send/receive text message, images, files with my teammates.
I have set up a rocket.chat service on my machine, but after some days using it, I really like this web-based chat service, but it's desktop notify feature does't work. So my teammates can't always response in time.
I am looking a server-less solution, it will be better if such software can scan all users in the same network automatically.
It should support Windows of course.
Any good suggestion?
