Open-source alternatives to Google Drive

3 community-reviewed projects you can use instead of Google Drive.

1. CryptPad - CryptPad is an end-to-end encrypted, open-source collaborative office suite with rich text documents, spreadsheets, presentations, forms, kanban boards, a whiteboard, a code/Markdown editor and an encrypted drive, where encryption happens in the browser so the server can never read your content. Use it free on a public instance or self-host it. (Licence: AGPL-3.0)
2. Nextcloud - Nextcloud is a self-hosted file sync, sharing and collaboration platform that lets you store and access files, calendars, contacts and documents on your own server or private cloud. It offers desktop clients for Windows/macOS/Linux, mobile apps, and a large app ecosystem including Talk and online office integrations. (Licence: AGPL-3.0)
3. Syncthing - Syncthing is a free, open-source peer-to-peer file synchronization program that keeps files in sync between two or more devices in real time, without storing data on a central cloud server. It runs on Windows, macOS, Linux, Android, iOS and BSD, with encrypted transfers and a web-based interface. (Licence: MPL-2.0)
