Project Management Options?

Hey everyone, I’m starting up an MSP in SoCal and wanted to get some input on project management solutions. Would prefer something self hosted and open source and would love a mobile app to help keep me on track. What do you guys recommend?

I’m in LA… Good Luck…

We mostly use Google Sheets for project management.

Nextcloud can do that with its built-in apps and such. In my head is possible, might need to test that out, haha.
