I have a dedicated machine from online.net that hosts a few services that would incur a monthly cost but self hosting helps save a bit of cash there. These are: GitLab for private projects (because I work with a team and per-seat costs multiply fast), Confluence and Jira for project management (again, team size scales the cost and a self-hosting license is only $20/yr).

As for actual SaaS: Backblaze personal, Adobe full suite ($400 per year I think, gives me everything I need for art/video projects), A password manager, and... that's it actually! No netflix, no google, no dropbox, I'll probably keep it this way.
