32 Android permissions requested, consistent with file sync, camera upload and background operation
Data lives on your own server; no third-party processor by default (GDPR/HIPAA-oriented architecture)

2024 academic analysis (King's College London / ETH Zurich) found three attacks on the E2EE feature; issues were disclosed responsibly and remediated or mitigated
Public CVE advisories on GitHub plus an active HackerOne bug bounty program
Open-source, community-audited code with commercial backing from Nextcloud GmbH
Very active development: 450 releases and ~89,000 commits on the server repository

Our verdict: the most complete self-hosted alternative to Google Drive and Microsoft 365 — if you can run or rent your own server.

Nextcloud is an open-source content collaboration platform you run on your own server, keeping files, calendars, contacts and video calls entirely under your control. Nextcloud Hub bundles file sync (Files), private conferencing (Talk), groupware, a LibreOffice-based office suite and workflow automation into one installation, and the project reports over 400,000 deployments across enterprises, governments and universities.

Because the software is self-hosted, no third party ever holds your data — a design that underpins its GDPR and HIPAA compliance story. The core is licensed under AGPL-3.0 and developed in the open on GitHub with a large, highly active community, while Nextcloud GmbH in Germany offers paid enterprise subscriptions with long-term support for organizations of 100 users and up.
