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.

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.

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.

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

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.

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.

With over 1,200 GitHub stars, 12,000+ commits, and more than a decade of active development distributed under the AGPL-3.0 license, Cozy Cloud operates as a comprehensive personal data hub that goes far beyond file storage by connecting your documents, contacts, calendars, banking transactions, energy bills, and productivity tools into a single self-hosted platform where no third party profiles you. The cozy-stack Go binary handles file storage, CouchDB document management, job scheduling, app serving, and the REST API in a single process consuming approximately 150MB of RAM idle. Sandboxed konnectors import data from 50+ external services — banks, utility providers, telecom operators, cloud drives — running as isolated jobs via nsjail to prevent untrusted code from accessing other user data. The built-in app store serves web applications in subdomain-isolated environments with Content Security Policy headers, each app communicating exclusively through the documented REST API. Real-time synchronization via PouchDB replication and WebSocket keeps files, contacts, and documents consistent across desktop clients, mobile apps for iOS and Android with automatic photo backup, and the web interface. Security features include automatic Let's Encrypt TLS certificates, Argon2id password hashing, optional TOTP two-factor authentication, and GDPR-compliant data export via the CLI. Each user receives their own isolated instance with independent storage, database, and application configuration.

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.

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.

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.

Upload files, get a share link, let it expire: PsiTransfer is a self-hosted WeTransfer with no accounts, no logins, and no third-party cloud with size caps and metadata harvesting. The engineering focus is large files over imperfect networks. Uploads use the tus.io resumable protocol, so a dropped connection on a multi-gigabyte video resumes exactly where it stopped once you're back online; downloads support HTTP range headers for the same resilience, and everything streams, so file size is bounded by your disk rather than memory. Files organize into upload buckets with retention you control: expire after a set time (up to weeks) or after a one-time download, with automatic cleanup when links lapse. Recipients need nothing installed - they open the link, preview files in modal views, and grab everything as a zip or tar.gz archive with one click. Buckets can be password-protected (AES-encrypted download lists), and security-through-obscurity is done properly: bucket URLs use hashed UUID tokens and stored filenames are replaced with UUIDs. An optional admin page (enabled by setting an admin password) lists bucket information and storage. The Vue.js frontend ships under 100 KB gzipped and is fully responsive. Honest caveat from the author: no end-to-end payload encryption yet. BSD-licensed, Docker-ready.

Plik lets you send big files the way WeTransfer does, except the server is yours: upload from the browser or one CLI command and get an expiring link to share. Files can delete themselves after the first download, stream straight from uploader to downloader without touching disk, or sit behind a password until their TTL runs out and cleanup removes them. End-to-end encryption with Age works between the CLI and the web interface, so the server only ever holds ciphertext. Recipients preview code with syntax highlighting, read rendered Markdown and Mermaid diagrams, and play media in the browser without downloading first. Storage lands on local disk, S3, OpenStack Swift, or Google Cloud Storage, with metadata in SQLite, PostgreSQL, or MySQL, and sign-in through local accounts, Google, GitHub, or OIDC. The web interface speaks twelve languages with light, dark, and custom themes, and Prometheus metrics plus an MCP server connect Plik to monitoring and AI assistants.

Most file sharing leaves copies lying around forever; Tessera shares things with a built-in goodbye. Drop in a file, a whole folder, a code snippet, or a link and you get back a short code and a URL that anyone can open until it expires or hits the download count you set, at which point it is deleted. Expiry is checked on every request and each retrieval is counted atomically, so a one-time share cannot be raced by two people at once. Passwords can be required before anything is shown, code arrives syntax-highlighted, and images, SVGs, and diagrams preview in the page, with link cards when you paste the URL into chat. Uploads resume after interruptions and stream through the server without ballooning memory at any size. Behind the scenes you choose where bytes live: local disk, S3-compatible storage, Azure Blob, Google Cloud Storage, or WebDAV, several at once, added or retired from the admin panel without a restart. Accounts are optional for a home server, sign-in through OpenID Connect suits a team, and roles with per-account quotas decide who may upload, view everyone's shares, or change settings. Optional malware scanning, anonymous-upload caps, and rate-limited code lookups keep a public instance honest. A CLI and API tokens drive the same endpoints as the web app, so scripts can share and clean up exactly like people. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

DashBeam sends files and folders of any size straight from one device to another, end to end encrypted, with no cloud account, no size limits, and nothing parked on a third party server in between. Drop in a file and share it through a short code, a link, or a QR scan; whoever receives it needs no account and can collect it in a plain browser tab with nothing installed. On the same network, nearby machines appear on their own, so pairing two devices and sending between them takes a couple of clicks instead of a cable or a memory stick. Pair a device once and it stays reachable by its identity, so your machines can exchange files from anywhere without swapping fresh tickets every time. Interrupted transfers resume where they stopped, and hopping from Wi-Fi to cellular mid-send does not drop the connection. One share can fan out to several receivers at once, and devices you mark as trusted can accept files automatically, which suits pushing builds, media libraries, or backups around a small fleet. You can preview what is arriving before downloading it, and a local history records every completed transfer. The repository also ships Docker Compose stacks for your own relay and discovery server, so even the encrypted fallback path can run entirely on machines you own. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

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.

Turn any server into a high-speed media vault and file-sharing hub with Chibisafe, a self-hosted upload platform built for chunked large-file transfers, organized albums, and instant desktop screenshot workflows. Users drag and drop photos, videos, archives, or documents into the browser uploader, where multi-gigabyte files are automatically split into chunks to prevent network drops from ruining an active transfer. Uploaded media renders inside a responsive masonry or list gallery with in-browser video and audio previews, custom file tags, search filtering, and one-click shareable links. Organizers group related uploads into folders and public albums, mark sensitive collections with content warnings before loading, and publish syntax-highlighted text snippets or code gists alongside shortened URLs. Desktop and mobile power users connect ShareX, iOS Shortcuts, macOS quick actions, fswatch folder monitors, or the companion browser extension using personal API keys that route captures straight into designated albums. Instance administrators toggle between public, open-registration, and invite-only modes, enforce per-user storage quotas, offload storage to AWS S3, Backblaze B2, MinIO, or Wasabi via signed URLs, and customize rate limits or allowed extensions directly from the web settings panel. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

LinShare gives organizations a file sharing service they run themselves, where every upload, share, and download is accounted for instead of scattering across inboxes nobody can audit, retract, or find six months later. Your personal space keeps files organized and versioned, ready to share by link or email with the people who should have them and no one else. Teams work in shared spaces with roles, nested folders, and shared drives, so a project keeps one canonical copy instead of eleven emailed variants. Need files from someone outside? Send an upload request and they drop documents into a secure, expiring drop box without ever getting an account. Regular external collaborators become guests with restricted, time-limited accounts, and contact lists make recurring groups of recipients reusable in one click. Administrators see the whole picture in activity logs that trace every download, share, and change, while antivirus scanning checks files as they move through the system. Previews spare everyone the download-just-to-check dance, and directory integration with LDAP and OpenID Connect single sign-on means accounts follow your existing identity rules. Everything an administrator can click, automation can call through the REST API, and an MCP server even lets AI assistants manage files, shares, and guests on your behalf. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Only the person holding the link can open what you share with SkySend, a self-hosted file and note sharing service that encrypts everything in the browser before it leaves your device. Sending a contract? Drop in the file, several files, or a whole folder, and share the link. Need documents from a client? Send an upload link instead, and whatever comes back is encrypted for you alone. Handing over a password or an SSH key? Write it into a note that burns after reading. Notes can mix text, Markdown, generated passwords, and highlighted code in a single page. Every share can expire by time, stop after a set number of downloads or views, and carry an optional password as a second lock. The command-line client uploads, downloads, and reads notes with the same encryption, and its full-screen mode shows each link as a QR code. No accounts are needed: My Links keeps your shares in the browser, and optional OIDC sign-in limits who may create them. Encrypted uploads sit on local disk or any S3-compatible bucket, and the interface offers 13 languages and three themes.
