- GrapheneOS
- I primarily use an iPhone these days, but this is undoublty the best operating system for a mobile device. Completely open source, hardened, and with sandboxed Google Play services.
- Bitwarden
- A free and open source cloud based password manager that can be selfhosted. Much better than LastPass or... God forbid... all your passwords in a browser!
- DW Service
- A free, open source remote viewing service that I like for monitoring and controlling machines, espeically family members' that I am responible for maintaining.
- FreeFileSync
Windows Only
- FOSS local file syncing.
- Stats for MacOS
- During my (technically second) experimentation with MacOS, I have found this piece of software extremely useful. It is much nicer for monitoring system resources than the actual Activity Monitor.
