Should you switch to Cryptomator?

The easiest way to keep using convenient cloud sync without trusting the provider with plaintext. A successful migration starts with a small real project, not a feature checklist. Test the files, integrations, shortcuts, and collaboration steps you use every week before removing the existing tool.

Open source gives you inspectable code and a path away from vendor lock-in, but it does not eliminate tradeoffs. Support may be community-led, some commercial file formats may be imperfect, and self-hosted options require security updates and backups.
