I really like Syncthing, Nextcloud, Forgejo and Mailcow to collaborate with colleagues.
Kimai allows me to track hours and get paid.
Barrier allows me to use several computers at once.
Xen Orchestra is pretty much on par with VMWare stuff and way cheaper.
What other awesome software does allow you to work more efficiently in a business context and stays out of your way?
Almost all commercial software is better designed and has a better interface than any FOSS project.
I say this having used FOSS since the late 1980s. Back then, it was EMACS on Sun or HP workstations.
But…
FOSS preserves privacy. Any business that uses commertial software tools which leaks private data to their competitors because of data mining just shot themselves in the foot.
If you’re a business, you can train your staff to use FOSS. And if you do, your business plans remain private.
Not really. I have used commercial IPAM and DCIM software and they all pale in comparison to Netbox, for example.
