Alternatives / Tresorit
Looking for an open source Tresorit alternative? We compared 12 open source file storage and sync platforms by license, encryption, self-hosting, and maintenance. Nextcloud and Seafile are the established suites, Ente is end-to-end encrypted photo storage, and Peergos is a decentralized encrypted filesystem.

| Alternative | Best for | License |
|---|---|---|
| Nextcloud | Complete file sync and collaboration suite | AGPL-3.0 |
| Ente | End-to-end encrypted photos and videos | AGPL-3.0 |
| Seafile | Sync with permissions and co-editing | AGPL-3.0 server / GPL-2.0 client / Apache-2.0 components |
| Filestash | File manager over many backends | AGPL-3.0 |
| OpenCloud | Self-hosted platform with office suite | Apache-2.0 backend / AGPL-3.0 web components |
| Sync-in | Storage and collaboration | AGPL-3.0-or-later |
| Peergos | Peer-to-peer encrypted filesystem | AGPL-3.0 core |
| ownCloud | Platform for regulated organizations | Apache-2.0 backend / AGPL-3.0 web client |
| Hoodik | Lightweight encrypted storage (non-commercial) | CC BY-NC 4.0 |

| Firefiles | Browser file manager over S3 (stale) | AGPL-3.0 |
We looked for open-source tools that store and share files like Tresorit, with attention to encryption and self-hosting. We verified each project's license, recent activity, stars, and self-hosting in its repository. Not all of them offer end-to-end encryption by default. See our methodology for the full criteria.
Nextcloud is the most popular: file sync and sharing with real-time editing, chat, a calendar, and many apps. Seafile offers file sync with granular permissions and co-editing, and OpenCloud and ownCloud are self-hosted file platforms for organizations.
Peergos is a peer-to-peer encrypted filesystem with offline access. Hoodik is a lightweight self-hosted encrypted store written in Rust and Vue. Ente encrypts photos and videos end to end, but it is focused on media, not general file sharing.
Filestash is a file manager across S3, SFTP, WebDAV, and more. Sync-in and Twake Drive are self-hosted storage and collaboration suites, Cozy imports data from other services, and Firefiles is a browser file manager over your own S3 storage.
Hoodik is under CC BY-NC 4.0, which forbids commercial use, so it is not open source in the usual sense. Filestash keeps its enterprise features in a paid version, and ownCloud is aimed at enterprise customers.
Nextcloud, Ente, Filestash, Sync-in, Twake Drive, Firefiles, Cozy, and Peergos core are AGPL-3.0. Seafile's server is AGPL-3.0. OpenCloud and ownCloud are Apache-2.0 backends with AGPL-3.0 web components. Hoodik is CC BY-NC 4.0.
Most had commits within days of this update. Firefiles' last commit was in November 2025.
Tresorit is a proprietary service with end-to-end encryption, priced per user, where files sit in its cloud. Open-source platforms let you host storage yourself and audit the code, but end-to-end encryption is often optional or limited, and you run the server.
Nextcloud is a self-hosted collaboration platform with file sync and sharing, calendar and contacts, real-time document editing, and chat and video calls through its Talk app. Communication is only one part of it, as it is primarily a file collaboration platform.
Pricing: Free self-hosted; paid enterprise subscriptions available.
Ente is an AGPL-3.0 encrypted cloud platform focused on private photo and video storage, automatic backup, albums, sharing, cross-platform clients, and self-hosting.
Pricing: Open-source clients and server; hosted storage plans may be paid.
Seafile is a self-hosted file synchronization and sharing platform with desktop and mobile clients, libraries, version history, permissions, and collaborative file workflows. Components use different open-source licenses.
Pricing: Open-source components are self-hostable; commercial editions and hosted services may be paid.
Filestash is an AGPL-3.0 web file manager that connects to S3, SFTP, FTP, WebDAV, Samba, and other existing storage systems, providing previews and a unified browser interface.
Pricing: Free and self-hostable; requires an existing storage backend and optional commercial services may exist.
OpenCloud combines file management, synchronization, sharing, spaces, search, permissions, WebDAV, office integrations, and cloud-native infrastructure. Its backend and web components use different licenses.
Pricing: Open source and self-hostable; commercial support or hosted services may be available.
Peergos is an AGPL-3.0-core encrypted peer-to-peer filesystem with client-side encryption, secure sharing, versioning, applications, messaging, and user-controlled data.
Pricing: Open-source core is self-hostable; hosted services and support may be offered separately.
ownCloud Infinite Scale is a self-hosted file synchronization and sharing platform with spaces, permissions, sharing, and collaborative integrations. Its backend and frontend components use different licenses.
Pricing: Open-source components are self-hostable; commercial offerings and support are available.
Sync-in is an AGPL-3.0-or-later platform for file storage, synchronization, sharing, WebDAV, team spaces, search, permissions, and collaborative document integrations.
Pricing: Free and self-hostable; verify current hosted and deployment options.
Hoodik is a Rust/Vue cloud storage platform that encrypts files in the browser before upload, so the server stores protected content rather than plaintext files. Its current license is CC BY-NC 4.0.
Pricing: Source available for non-commercial use under CC BY-NC 4.0; commercial use requires a separate agreement.
AGPL-3.0 personal cloud platform for files, personal data, and applications. Password management can be part of its ecosystem, but it is not a dedicated LastPass-style credential manager.
Pricing: Open-source self-hosted platform; hosted offerings may be available.
Twake Drive is an AGPL-3.0 file storage and sharing platform from LINAGORA, with browser-based file management, collaboration, sharing, Docker deployment, and self-hosting.
Pricing: Open source and self-hostable; hosted services may be offered separately.
Firefiles is an AGPL-3.0 web file manager that turns existing S3-compatible storage buckets into a browser-based cloud drive with previews and bulk uploads.
Pricing: Free and self-hostable; requires an external object-storage backend.
