Google Workspace and Microsoft 365, replaced by a platform you actually control: Nextcloud is the self-hosted digital workspace. Files is the core: file storage and sync across desktop, mobile, and web clients, with sharing, versioning, and collaboration built in. Around it, Talk provides private text chat, audio/video conferencing with screen sharing, SIP integration, and persistent voice rooms; Groupware bundles calendar, contacts, and mail with delegation support; and Office offers two collaborative suites - the Collabora-based option with deep ODF support, and Euro-Office, whose local-processing architecture delivers strong Microsoft Office compatibility and fast browser rendering with reduced server load. The Nextcloud Assistant threads AI through the platform via a context-aware sidebar, Whiteboard covers visual collaboration, Flow handles automation, and an app ecosystem of hundreds of extensions adds everything from Kanban boards to end-to-end encryption. Hub 26 brings a lighter UI with a unified app switcher and Nextcloud Governance for organizations under strict regulatory requirements. This is the flagship of data sovereignty: your files, chats, calendars, and documents live on your server, under your jurisdiction, with GDPR compliance by architecture rather than by contract.

The project that proved organizations could have Dropbox-style convenience with complete data ownership: ownCloud is the original open-source file sync and share platform - the codebase Nextcloud later forked from. This deployment runs the classic ownCloud Server (PHP over PostgreSQL or MariaDB, with Redis caching), the battle-tested edition trusted across enterprises, universities, and public institutions worldwide. The core loop: store files on your server, sync them via desktop clients for Windows, macOS, and Linux plus iOS and Android apps, and access everything through the web interface or standard WebDAV. Sharing is granular - internal users and groups, external recipients via public links with passwords and expiration dates, and federated sharing that connects separate ownCloud instances into one network. Security controls include file firewall rules, multi-factor authentication, encryption, and detailed audit-friendly lifecycle management with versioning and trash-bin recovery. An app marketplace extends the platform, and Web Office integrations bring collaborative document editing through Collabora Online, OnlyOffice, or Microsoft Office Online directly into your files. LDAP and Active Directory integration slots it into existing identity infrastructure. For teams that need a proven, self-hosted alternative to Dropbox or Google Drive - where compliance demands knowing exactly which disk your data sits on - ownCloud remains a foundational choice.

Organizations seeking complete data sovereignty over their documents, spreadsheets, and shared project folders can deploy OpenCloud as a self-hosted workspace for file sync, sharing, and real-time collaboration across web, desktop, iOS, and Android clients. Teams organize departmental assets inside dedicated Spaces where files belong to the project rather than individual user accounts, ensuring continuity when personnel change and enabling delegated space managers to assign granular read, edit, or upload permissions. Through built-in WOPI integration with Collabora Online, multiple colleagues can co-edit Microsoft Office and OpenDocument files simultaneously in the browser with automatic conflict locking and version history recovery. External partners and clients can access files via password-protected public links with custom expiration dates or upload deliverables into write-only File Drop folders without seeing existing directory contents. Cross-organization collaboration works seamlessly over the Open Cloud Mesh federation protocol, while full-text and tag-based search locates documents across personal and shared drives in seconds. Client devices synchronize changes in real time with support for virtual files on demand, resumable chunked uploads, and offline mobile access with camera document scanning.

Somewhere in every organisation there is a folder called FINAL_v2 that nobody dares delete, and Drive from La Suite exists to end that. It gives teams a shared file space where uploads land in organised workspaces, versions stay findable through search, and every file or folder carries its own access list. You preview PDFs, images, audio, and video in the browser, and office documents open for editing through Collabora or OnlyOffice without downloading a thing. Sharing reaches outside the organisation too: invite external partners by link, even without an account, and revoke access the moment a project ends. Uploads pass malware scanning before they touch storage, a trash bin restores accidents, and quotas with usage metrics keep big archives honest. Administrators plug in their own OIDC identity provider, so logins follow the same single sign-on as the rest of the stack, while an embeddable file picker lets other internal apps reuse Drive as their document library. Because the data lives in your own S3-compatible storage, sovereignty requests stop being an argument with a vendor and become a setting.

FileBrowser Quantum is an open-source, self-hosted web file manager that transforms any directory tree or mounted storage volume into a fast, searchable cloud drive accessible from any browser. You can mount multiple independent filesystem sources at once and apply custom include or exclude rules to keep sensitive system folders hidden from everyday browsing. A background indexing engine powers instant as-you-type search across millions of files, letting you filter results by file size, folder size, media type, or modification date in milliseconds. Rich media thumbnails render automatically for videos, office documents, audio album artwork, and interactive 3D models, while integrated OnlyOffice support lets you edit spreadsheets and word processing documents directly inside your browser tab. Built-in WebDAV server support allows desktop operating systems and mobile file apps to mount your remote directories as native network drives. Sharing files with external collaborators takes seconds through customizable public or private links with expiration timers, download limits, password protection, anonymous upload permissions, and custom branding themes. Administrators can authenticate users via OpenID Connect, LDAP, JSON Web Tokens, proxy headers, or local passwords with two-factor authentication, then enforce path-level read, write, and delete rules per user or group. Developers and automation engineers can generate long-lived API tokens and explore the interactive Swagger endpoint to script file transfers and directory provisioning.

Jmal Cloud is a self-hosted private cloud drive that keeps your files on your own server, with online previews, resumable uploads, full-text search, and WebDAV access. The web manager previews photos, videos, Office documents, PDFs, EPUB books, and even CAD DWG drawings in the browser, then puts recently modified files, favorites, shared folders, and a trash bin a click away. Huge uploads resume from the exact chunk that stopped, while full-text search drills into text, PDFs, and Office documents when filenames fail you. Connect Alibaba Cloud OSS, Tencent Cloud COS, or MinIO as storage backends and browse every bucket through the same folders. Wire in a self-hosted OnlyOffice Document Server and draw.io to edit Word, Excel, and PowerPoint files and sketch flowcharts or mind maps without leaving the drive. Mount the library as a local network drive over WebDAV, share folders through links for upload and download, and push scheduled backups with the Rust jmalcloud CLI. Packages and Docker images cover Ubuntu, Debian, CentOS, Fedora, and Arch on x86_64 and ARM64, and the interface speaks English, Chinese, and Japanese.

FolderHost turns a folder on your server into a private cloud that you and your team reach from any browser, with the whole platform shipping as one executable of about 19MB and zero dependencies to install. Upload, download, move, copy, rename, archive, and extract files through a familiar explorer interface, with chunked uploads that survive big transfers and a recovery bin that keeps accidental deletions restorable within limits you set. Code files open in a real editor where several people can type at once, which makes it a surprisingly handy way to tweak server configs or a game server's files together live. Long-running programs can be registered as services and started, stopped, and driven from a built-in terminal that shows live uptime and memory use. Accounts come with granular permissions for every action, optional folder scopes that confine a user to one directory tree, and per-instance storage quotas. Every activity lands in audit logs you can review and auto-expire, sessions use short-lived tokens tied to the login device, and TLS can be self-signed for a LAN or issued through Let's Encrypt for a public domain.

OxiCloud is a self-hosted cloud for files, photos, calendars, contacts, and office documents. Drives can be personal or shared, with configurable storage quotas. Multi-gigabyte uploads travel as parallel, resumable chunks with integrity verification. Images, PDFs, audio tracks, and video streams preview right in the browser, and photos show EXIF details and map locations. Files sync over WebDAV. Calendars sync over CalDAV. Contacts sync over CardDAV. Desktop file managers, Thunderbird, Apple Calendar, and mobile DAVx5 clients connect without proprietary software. Collabora Online or OnlyOffice plug in through WOPI for real-time co-editing of spreadsheets, presentations, and text documents. Administrators enforce role-based access controls. Sign-in runs through OpenID Connect providers such as Keycloak, Authentik, or Azure AD. Public share links can carry a password and an expiration. Identical files are stored once, and adaptive compression keeps footprints compact. Local disks, Amazon S3, and Azure Blob can be mounted at the same time, with live background migration and automated consistency checks.

Your files already live in five places; filex puts them in one tree and serves that tree back out through almost any protocol. Mount local disks, S3 buckets, SFTP servers, WebDAV shares, FTP sites, and SMB network drives side by side, then copy in one storage and paste into another without thinking about where anything physically sits. The same tree is reachable as S3, SFTP, FTPS, NFS, and WebDAV, so rclone, restic, the AWS CLI, WinSCP, or FileZilla all work against it with the same per-user and per-folder permissions as the web interface. Sharing leaves the server under your control: public links carry a PIN, an expiry, and a download limit, and file-request links let people upload into a folder without seeing its contents. Anything deleted stays recoverable inside a retention window, overwritten files keep version snapshots, and encrypted folders are sealed in the browser so the server never receives a key. People sign in with OIDC single sign-on, LDAP or Active Directory, or the host machine's own accounts, with roles, groups, and tenants plus folder-level exceptions. A desktop app keeps chosen folders in sync within about a second, the file manager embeds into other products as a web component, and an MCP server plus REST API let agents work the same tree. It runs from one static binary or container on port 5212. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Alarik is a self-hosted S3-compatible object storage server that lets you store files, backups, media, and application data on your own hardware while keeping the S3 APIs your tools already expect. Create buckets, upload objects with multipart support for large files, and retrieve them again through core operations, range reads, presigned URLs, and bucket or object tagging. Versioning keeps earlier copies, delete markers, and listings under your control, while lifecycle rules expire old versions and clean up incomplete uploads automatically. The web console lets you drag and drop files or whole folders, search recursively across nested folders, edit metadata in place, preview individual versions, and share time limited public links. Administrators manage users, access keys, bucket policies, and public access blocks from the same console, with live charts for CPU, memory, traffic, and storage. Bucket webhooks send event notifications when objects change, and replication rules continuously copy data to remote S3 compatible targets, synchronously or asynchronously per rule. Clusters add erasure coded storage across nodes, read repair, bit rot scrubbing, and automatic rebalancing when nodes join, drain, or return.

Tools and applications that already speak S3 can use RustFS as their storage backend, so backup jobs, data pipelines, and services keep working while the data stays on infrastructure you control. A built-in web console on port 9001 manages buckets, object uploads and downloads, access keys, users, groups, and IAM policies, with a status page for cluster health, capacity, and scanner activity. Versioning, Object Lock retention, bucket quotas, and server-side encryption with Vault or AWS KMS backends protect objects once they land. Lifecycle rules expire or transition data, and tiering moves cold objects to remote targets such as Amazon S3 or Wasabi. Bucket replication and site replication keep clusters in sync, and event notifications call webhooks when objects change. Single-node mode suits a lab or small server, while distributed mode adds erasure coding, bitrot protection, background healing, and pool expansion or decommissioning as capacity grows. Sign-in works with local users, OIDC single sign-on, or OpenStack Keystone, and FTPS and WebDAV are available by default, with SFTP and the Swift API as opt-in builds. A preview of S3 Tables exposes an Iceberg REST catalog for tools such as DuckDB and PyIceberg, and a documented migration path moves existing MinIO deployments across. Typical uses include backups, container registries, logs and traces, data lakes, and AI training sets.

Sending a client a big file should not mean renting seats on someone else's cloud, and PlikShare turns your own server into a file sharing platform with unlimited users, unlimited workspaces, and no per-seat pricing. Its central idea is the box: a controlled gateway between your folders and the outside world, where you invite collaborators, mint anonymous links, and decide who may upload, download, preview, or drop files into an upload-only inbox. Quick share links carry custom slugs, expiry dates, passwords, and download caps, and every box can embed into another website as a live widget whose permissions update the moment you change them. Storage is your choice per workspace, from the server's own disk to S3, Cloudflare R2, Backblaze B2, Azure Blob, Google Cloud Storage, or any S3-compatible server, and each storage picks one of three encryption modes, including full encryption where names and contents are sealed with keys derived from each user's password. Bulk uploads arrive as a single zip that rebuilds its folder structure on landing, bulk downloads assemble from an explorer tree, and previews cover video, audio, PDFs, Markdown with diagrams, and even the inside of zip archives. Single sign-on through multiple OIDC providers, granular admin roles, an optional MCP server for scoped AI agents, and OCR or chat integrations round out a platform that stays lean on a small server.

Peergos is a peer-to-peer encrypted drive, messenger, email client, and private social network where your files and friendships stay unreadable to the server that stores them. You browse, upload, and organize files in a familiar web drive, then share a folder with a friend or send anyone a secret link whose key never travels to the server, so the link itself cannot leak what it opens. The built-in messenger handles private conversations, an encrypted email client with a bridge reaches the outside mail world, and the social feed shows posts only to the people you chose, with even the friend graph hidden from the operator. Web apps run from Peergos inside a sandbox and see only the data you grant them, which turns the drive into a private place to run tools rather than a folder other services reach into. Because encryption happens on your machine before anything is stored, a compromised server yields ciphertext and no file names, sizes, or sharing relationships. Host it at home and the same account gives your household storage plus its own communication platform; log in from any browser without carrying keys, because your password rebuilds them.

When a client needs a two-gigabyte video and your options are a consumer transfer site with a weekly cap or an FTP account older than your interns, FileSharing gives you a private WeTransfer of your own. You group files into a bundle, drag them in from your filesystem, and keep adding more days later if the project grows. Every bundle produces two links: a preview link where recipients see the file list first, and a direct link that downloads everything at once, both guarded by an authorization code. Bundle settings cover a title, a description, an expiration date, a maximum download count, and an optional password that also encrypts the ZIP archive recipients can pull down. Upload access stays yours to control through an IP allowlist, login and password accounts, or a mix of both. Optional duplicate prevention skips files you already sent, a download rate limiter keeps a single recipient from saturating your bandwidth, and a scheduled background task physically deletes expired bundles so old transfers do not pile up. There is no database to run or back up because bundle metadata lives in JSON files on disk, and the interface speaks English, French, German, and Korean.
