File sync with nobody in the middle.
FreemacOS · Android · Websync · files
✓Why we picked it
Keeps folders identical across your machines by talking to them directly, so there is no storage tier to outgrow and no company holding the files. Once configured it runs for years without attention.
◇The catch
First setup is genuinely fiddly, and there is no first-party iOS app.
