Best Open Source Alternatives to Google Drive & Dropbox
Sovereign cloud storage, continuous desktop sync, and team file sharing backed by your own disks or object storage.
Why Migrate from Google Drive & Dropbox?
Commercial cloud storage providers inspect file contents for copyright claims, enforce restrictive bandwidth limits, and lock organizations into escalating storage tier pricing. Self-hosted storage platforms give you terabytes or petabytes of storage at raw disk cost, full end-to-end encryption, and seamless mobile and desktop syncing.
Key Risks & Constraints
Operational and financial risks of continuing to rely on Google / Dropbox:
- ⚠Automated file scanning, automated content flagging, and arbitrary account terminations
- ⚠Escalating recurring storage subscription fees
- ⚠Compliance and GDPR violations storing confidential client data in US cloud regions
- ⚠Bandwidth throttling and restrictive download link limits
