Private text, encrypted before it leaves the browser: Enclosed turns passwords, keys, and other secrets into a link that only its holder can open, with no third-party service in between. Can the server read the note? No. It stores only ciphertext and settings, because the decryption key rides in the part of the link after the # sign, which browsers never send. Want a second lock? Add a password, or generate a random one with a click, and share it by another route. Worried about links lingering in chat history? Pick one hour, one day, one week, or one month, and tick Delete after reading so the first view removes the note, with a warning shown to the recipient beforehand. Need more than text? Attach files by button or drag and drop, and recipients download them one by one or all at once. Sending to a phone? Every finished note offers a QR code, downloadable as SVG or PNG. Setting it up for a team? Restrict note creation to signed-in users, create notes from the command line, and let people read the interface in 17 languages with light, dark, or system themes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

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.

Upload a file, get a unique download link and a separate delete link - Jirafeau has done exactly this one thing since 2008. It is plain PHP with no database, no mail server, no JavaScript framework, and no external dependencies - files and metadata live on the filesystem, which is why it runs on nearly anything and why it has outlasted most of its imitators. Uploads use the HTML5 file API, so PHP's post_max_size ceiling does not constrain file size, with live progress showing speed, percentage, and time remaining. Every upload takes options: expiration from one minute to a year to unlimited, self-destruct after first download, and password protection with configurable policy - passwords can be optional, required, or server-generated with complexity rules. Server-side encryption (modern builds use XChaCha20-Poly1305) stores files encrypted at rest with the decrypt key embedded only in the download URL, never on the server, so a compromised host cannot read the contents. Unencrypted deployments get file-level deduplication - identical files stored once with multiple links. Upload access can be gated by password lists or IP allowlists, a small admin panel manages stored files, and a CLI cleanup script handles expired files via cron. Recipients can preview supported files in-browser.

QuickDrop functions as an ephemeral, self-hosted file distribution node and pastebin that eliminates account requirements for rapid data transfers. Users can drag individual files, paste plain text code snippets, or drop entire folder structures while preserving complete directory hierarchies through automated client manifests. Resumable chunked transfers split multi-gigabyte payloads into resilient blocks, ensuring dependable uploads over unstable network connections. Senders can protect sensitive documents with optional AES encryption at rest, individual passphrase requirements, and automatic metadata stripping that removes GPS coordinates and camera EXIF markers. Granular share token policies restrict access by enforce maximum download quotas, burn-after-reading limits, or strict calendar expiration timestamps. In-browser viewers generate instant previews for code syntax, Markdown documentation, PDF reports, audio tracks, and high-resolution images without downloading files locally. Built-in QR code generators allow mobile devices to retrieve shared payloads instantly across local wireless networks. System operators can govern storage lifecycles through an administrative control panel with configurable retention windows, automated background garbage collection, and custom storage caps.

With nearly 3,000 GitHub stars and active development since 2014 through version 14.2.0, Yopass eliminates the universal bad habit of sharing passwords and API keys through Slack messages, email threads, and ticket systems by encrypting secrets entirely in the browser using OpenPGP before anything reaches the server. The Go backend stores only ciphertext — it never sees plaintext — while the React frontend handles all encryption and decryption client-side, generating one-time URLs that self-destruct after a single viewing or when the configured expiration of one hour, one day, or one week passes. File upload support streams encrypted files with configurable size limits, and optional custom password protection adds a second encryption layer beyond the URL-embedded key. The server supports Redis or Memcached as storage backends with automatic key expiration, deploying via Docker Compose in under five minutes or as Kubernetes manifests for production environments. Built-in TLS support works alongside reverse proxy configurations for Nginx, Caddy, and Traefik with automatic Let's Encrypt certificate provisioning. Prometheus metrics expose HTTP request counts, latency histograms, and secret lifecycle counters for Grafana dashboard integration and alerting. Read-only mode enables split-instance deployments separating secret creation from retrieval across different network zones. Multi-language support localizes the interface for international teams. The open-source core under Apache 2.0 provides full self-hosted functionality with no account management required. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Credentials sitting forever in email threads and chat scrollback - Password Pusher solves that everyday security failure. Instead of pasting a password into Slack, you push it - a password, note, file, URL, or QR code - and share a unique one-time link that expires after a set number of views, a time limit, or both. Content is encrypted at rest with AES-GCM under a configurable master key, optionally guarded by a passphrase, and permanently deleted from the database the moment it expires; a retrieval-step option keeps URL-scanning bots from consuming views. Full audit logs record when each link was created and viewed (and by whom, with logins), and TOTP two-factor authentication can be required instance-wide. The delivery page is deliberately unbranded - no logos or confusing links for recipients - and the interface ships in 31 languages with light and dark themes. Automation runs through a JSON API (v2), an official CLI for pushing and expiring secrets from the terminal, a Chrome extension, and a catalog of third-party integrations. Apache-2.0 licensed Ruby on Rails, deployable via Docker, Kubernetes, or Helm, with SQLite or PostgreSQL storage - the sysadmin staple for sending credentials that clean up after themselves.

PrivateBin shares text and files with true zero-knowledge encryption: the server stores only ciphertext it cannot decrypt because the key exists exclusively in the URL fragment that never reaches the server. With over 8,400 GitHub stars and 500,000+ Docker pulls, it has become the standard for privacy-respecting paste sharing where not even the hosting operator can read stored content. All encryption uses 256-bit AES in Galois Counter mode performed entirely client-side in the browser. Burn-after-reading mode destroys pastes on first view, while configurable expiration timers automatically purge content after periods ranging from five minutes to forever. Optional password protection adds a second encryption layer requiring recipients to enter a passphrase before decryption occurs. Discussion threads enable anonymous or nickname-based commenting on pastes with IP-based identicon avatars for visual identity. Markdown rendering with live preview formats pastes as styled HTML, and syntax highlighting through prettify.js supports dozens of programming languages across four color themes. File upload support enables sharing images, PDFs, and media files with in-browser preview. QR code generation converts paste URLs for mobile device transfer. Customizable templates include Bootstrap 5, classic Bootstrap CSS, and Darkstrap themes. Storage backends support filesystem, MySQL, PostgreSQL, SQLite, Amazon S3, and Google Cloud Storage. Deploy via Docker with the privatebin/nginx-fpm-alpine image on port 8080.

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.

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. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-2.0-or-later 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.

Browse, upload, edit, preview, and archive the files on your server from any web browser, with no FTP client, no shell session, and no database to set up. Tiny File Manager lists every folder in a sortable table showing size, modified date, permissions, and owner, with a search box that filters as you type. Drag files into the upload zone, send several at once, or paste a URL for the server to fetch. Rename items, select several to copy, move, delete, or pack into a zip or tar archive, and extract uploaded archives on the server. Click any text file to open the built-in editor, which offers syntax highlighting for 150+ languages and 35+ color themes, so quick fixes to configs and scripts happen where the files live. Images, audio, video, and text open in a preview without downloading, and every file has a copyable direct link. Give teammates or clients their own accounts, each locked to a root folder you choose, mark accounts read-only, and limit uploads to approved file extensions. Hide folders you never want listed, restrict access with IP allow and block lists, switch between light and dark themes, pick from 35+ interface languages, and use the responsive layout on a phone. Setup is one file copied to a web server, or one Docker container. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

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.

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.

End-to-end encrypted by design, CryptPad is a real-time office suite where teams write documents, plan on kanban boards, collect answers with forms, and draw diagrams without the hosting server ever seeing their content. Rich text pages come with comments, replies, @mentions, and a document outline, while the Markdown editor adds a live preview, Mermaid diagrams, mind maps, and math. Kanban columns hold colored, tagged cards with Markdown bodies, and the diagram editor exports PNG, JPG, SVG, or PDF. Optional ONLYOFFICE editors add spreadsheets, word-processing documents, and presentations that several people can edit together. The form builder offers text, choice, grid, date, ranking, and poll questions, conditional sections, and separate author, auditor, and participant roles. Documents can be shared with contacts or teams, by link, or as embed code, with view, edit, present, or view-once access. Passwords, expiry dates, owner lists, and access lists limit who gets in, and every edit lands in a history you can step through, restore, or pin as a named snapshot. CryptDrive keeps files in folders, tags, templates, and a trash bin, while teams get their own drive, chat, and member roles.

Standard Notes keeps your notes, files, and tags encrypted on your device before anything touches the network, meaning the server stores only ciphertext it cannot read. Cross-platform sync across desktop, mobile, and web delivers fast, conflict-free updates on unlimited devices with the same zero-knowledge guarantee that only your password can decrypt your content. The V2 server architecture condenses everything into four Docker containers consuming roughly 570MB RAM total (down from 13 containers and 1.7GB in the legacy setup), with startup under one minute. Revision history automatically preserves every version of every note, so recovering deleted text or reverting to a previous state never depends on manual backups. A nested tag system organizes thousands of notes with hierarchical categorization that goes well beyond flat folder structures, while search operates entirely on client-side decrypted content. File attachments of any type encrypt and sync alongside notes with identical end-to-end protection. Multiple editor options span plain text, Markdown with preview, and rich formatting to fit different writing workflows. Two-factor authentication via TOTP with email backup codes adds a second barrier beyond your password. An optional separate container serves the web frontend, providing browser access to your encrypted vault without depending on standardnotes.com infrastructure. With 5,500+ GitHub stars and active development, the project continues expanding editor plugins and sync improvements.
