RPort remote management of any IT-infrastructure - free and open-source Manage Windows, Linux, and any IoT device from one central console. Securely log into remote systems behind firewalls and without fixed IP addresses. https://rport.io
Easy to use. No data is shared with external companies. I can manage all my systems - Windows and Linux, from a central place. And the best: It's free. I'll kick out Teamviewer soon.
It works tons better for headless Linux systems where I just need a SSH log in like all other solution I've seen.
The project is still young, but they announced 2F. Awesome.
This new software has a big potential to become a serious competitor of Teamviewer, Anydesk and all the others RMM tools. The first and only true open-source option I know.
The installation on my tiny DO instance took 10 minutes and now it runs flawlessly. I can log in to all my systems and I don't need to care about port forwardings on the router. The UI is nice and gives a good overview. Perfect for MSPs.
