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.

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. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

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.

By routing file transfers directly between client browsers and S3-compatible object storage through time-limited presigned URLs, Safebucket enables organizations to share large files and folders without bottlenecking their application server. Teams organize documents into logical buckets with nested folder hierarchies, preview images, videos, audio tracks, and PDFs inside a sandboxed browser viewer, or bundle up to one hundred selected items into a single client-side ZIP download. Public Quick Share links let external recipients download files or entire folders from a browser or via command-line curl redirects, while Reverse Share turns any shared folder into a secure dropbox where guests can upload files back under size and count quotas. Every shared link supports optional password protection, expiration dates, and maximum view limits, complemented by per-file expiration timers and a soft-delete trash bin with configurable retention. Two-tier role-based access control pairs platform roles (Admin, User, and Guest) with bucket-level permissions (Owner, Contributor, and Viewer), allowing teams to invite external collaborators via challenge-verified email links. Authentication integrates with OpenID Connect identity providers and LDAP or Active Directory servers alongside TOTP multi-factor authentication. Administrators gain a four-view governance console covering platform storage metrics, user and bucket inventories, and searchable audit trails filtered by action, user, and date range.

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. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

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.

ProjectSend gives every client a private, signed-in page on your own server where only the files you assigned to them appear, so contracts, photo shoots, and quarterly reports skip the third-party file-sharing service. You upload once, then share a file or a whole folder with one client, a group, or anyone holding a public link, with an optional expiry date or download limit. Clients search, preview, and download files one by one or as a zip, whole folders included, comment on a document so questions stay beside it, and send files back within the quota you set. Uploads of up to 2 GB travel in resumable pieces, so a dropped connection pauses a transfer instead of ruining it. Folders, categories, custom client fields, and linked file versions keep a growing library tidy, while roles with granular permissions let staff work without becoming administrators. The activity log and download history record who received what and when, and the log exports to CSV. Sign-in works with email and password, LDAP, or Google and Microsoft accounts, with optional two-factor authentication. Your logo, watermark, themes, and editable email templates carry your brand, and the interface is translated into 16 languages. Optional virus scanning quarantines suspicious uploads, and a REST API with scoped tokens automates uploads, sharing, and account management.

With nearly 9,000 GitHub stars and adoption by over 60,000 companies across 100 countries, Papermark is the open-source DocSend alternative that turns document sharing into a data-rich conversation between you and your viewers. Every shared document generates page-by-page analytics showing exactly which pages capture attention, how long viewers spend on each section, where they drop off, and whether they return for a second look, with real-time notifications the moment a document is opened. Virtual data rooms support unlimited folders with drag-and-drop organization, bulk uploads, granular per-viewer permissions, dynamic watermarking that stamps each page with the viewer's identity, and NDA gating that requires agreement before access. Custom branding applies your logo, colors, and custom domain to every shared link and download page, while email verification and password protection add authentication layers. The AI Data Room Copilot lets viewers chat with uploaded documents, ask questions, and receive contextual summaries directly within the data room interface. The developer platform exposes 43 REST API operations covering data rooms, documents, folders, links, visitors, and analytics, with an MCP server for AI agent integration and a CLI for automation. Built on Next.js with TypeScript, Prisma ORM, PostgreSQL, NextAuth.js authentication, and shadcn/ui components.

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.

Filestash puts a Dropbox-style web interface in front of the SFTP servers, S3 buckets, SMB shares, and WebDAV storage you already run, so no file has to move. Administrators enable each connector, including FTP, NFS, Git, Dropbox, Google Drive, Storj, IPFS, and Backblaze B2, from one admin console. Colleagues browse, rename, move, and upload in a single folder view, with resumable uploads for big transfers. Thumbnails cover JPEG, PNG, WebP, TIFF, HEIF, and RAW photos. Images open with an EXIF info panel, and PDFs, audio, video, and EPUB ebooks open right in the browser. A CodeMirror editor handles text and code, and HLS transcoding streams video on demand. Outside guests get a shared link instead of credentials, with an optional password, an expiry date, and read, write, or upload-only rights. Limit a link to one email address or a whole domain, or mount it as a network drive. A workflow engine chains emails and HTTP calls after file events, webhooks, or schedules. Flip one admin setting and Claude, ChatGPT, and Mistral Le Chat can use the connected storage as MCP tools. Downloadable file apps add Office documents, 3D models, and GIS maps. Runtime plugins are zip files dropped into the plugins folder. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

Sharry moves files in both directions: you hand someone a download link, and they hand files back to you, without either side juggling accounts on a commercial transfer service. Upload a file and you get a public URL that is hard to guess but open to anyone who has it; add a password as a second secret, set how long the share lives, and cap how many times it may be downloaded. Expired shares clean themselves up on a schedule. Uploads run over the tus protocol, so a dropped connection in the middle of a two-gigabyte video is an inconvenience, not a restart: send the same file again and it resumes from the last received chunk. Downloads support caching and range requests, which means recipients can stream a video in the browser and scrub its timeline instead of waiting for the whole file. The reverse direction is what makes Sharry unusual: every registered user can maintain alias pages behind their own unguessable URLs, where clients, students, or family members upload files straight to that user, with an email notification when something arrives. Everything is scriptable through a documented REST API, and files can live in the database, on the filesystem, or in S3-compatible storage.

Pingvin Share X is your own WeTransfer, running on your server, with none of the transfer limits or expiring-link anxiety of the free tiers. Drop in a file of any size, get a link, and decide exactly how it behaves: an expiration date after which it vanishes, a password gate, a cap on how many visitors may open it, or all three. Email the link straight to recipients from the share dialog, and get notified when they download. Reverse shares flip the flow around: send someone a link and they upload files to you through it, which is perfect for collecting client deliverables, application documents, or the family photo archive without a single email attachment thread. Attachments can be scanned with ClamAV before anyone touches them, and storage lives on your disks or in S3-compatible buckets. Accounts connect through OIDC or LDAP single sign-on for teams, and an extensive admin panel tunes everything from password policy to upload chunk sizes. Registration rules decide whether your instance is a private family tool or an open drop point for your whole crew.
