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.

A video too large for Discord, a secret that should not live in a chat log, or a config file a headless server needs to fetch: MicroBin turns each into a short link with an animal name, served from your own machine. Paste text or code and it comes back with syntax highlighting, inline image and video embedding, and a QR code for moving it to a phone. Attach one file or several, then decide exactly who can see them: uploads can be public or private, editable or locked, set to expire on a schedule or to never expire. For sensitive material, server-side encryption and client-side end-to-end encryption keep contents unreadable without the password. Raw serving hands the plain bytes to curl, a browser, or another program, which makes the same box a tiny file endpoint for scripts and test rigs. A postbox mode lets people send you files and texts they cannot browse or delete afterwards, and a read-only mode with an uploader password turns the instance into a drop point with exactly one trusted sender. The admin console lists uploads and storage, and everything runs as one small binary backed by SQLite or a JSON file, comfortable in a few megabytes of memory.

Paste some text, hit save, share the link - Hasty Paste is a fast, minimal pastebin written in Python on the async Quart framework, named, by its author's own admission, "because you use it so fast without a care in the world." No accounts, no authentication, no friction - built for the everyday case of handing a debug log, config snippet, or stack trace to someone in tech support or a chat channel. Pastes get randomly generated IDs, with an optional "long" ID mode that makes brute-force URL guessing impractical, and expiry times ensure throwaway content actually gets thrown away. Optional Pygments syntax highlighting makes code readable, a dark theme spares your eyes, and the whole interface works without JavaScript - it renders in terminal browsers and under the strictest script blockers. Storage is a custom flat-file system (no database), caching runs internally or through Redis for busier instances, and a REST API plus the companion "Hastily Paste It" CLI script enable piping command output straight into a paste from the terminal. The Alpine-based Docker image is tiny, resource usage is minimal, and the license is AGPL.

Share code snippets, logs, configs, and notes without registration, tracking, or ads: Lenpaste is a minimal, self-hosted, anonymous alternative to pastebin.com. It is deliberately spartan in the right ways: no accounts, no JavaScript required (the entire site works in text browsers and hardened setups), and cookies used solely to store display preferences. Pastes support syntax highlighting across a long list of languages (from ApacheConf and Arduino to mainstream stacks), configurable expiration from minutes to unlimited, one-use "burn after reading" pastes that self-delete on first view, optional author attribution, and iframe embedding for dropping pastes into other pages. The form-encoded HTTP API covers everything the UI does - create pastes with title, syntax, expiration, and line-ending normalization, fetch them by ID, and query server capabilities - making it trivial to pipe command output to your paste server from shell scripts. Server operators control maximum title and body lengths, maximum paste lifetime, rate limits for viewing and creation, search-engine indexing policy, and can lock private instances behind HTTP Basic authentication. It deploys as a single lightweight Docker container, giving your team a snippet-sharing endpoint where the content never touches a third-party service.

Every code snippet in Opengist lives inside a real Git repository that you can initialize, clone, pull, and push over HTTP or SSH while browsing syntax-highlighted files, revision diffs, and Markdown documents through a self-hosted web interface that replaces GitHub Gist. Create public, unlisted, or private multi-file gists directly from your browser, terminal Git client, or the OpenAPI-documented REST API v1 using personal access tokens. Rich rendering displays source code across hundreds of languages alongside Markdown documents with Mermaid diagrams, LaTeX math, CSV tables, images, and downloadable ZIP archives. Full-text code and metadata search powered by Bleve or Meilisearch lets teams locate snippets by content, filename, extension, language, user, or topic tags in milliseconds. Users can star, fork, archive, and embed snippets into external websites via JavaScript widgets or fetch raw files and structured JSON payloads. Enterprise authentication supports GitHub, GitLab, Gitea, OpenID Connect, and LDAP directories, reinforced by TOTP two-factor authentication and WebAuthn passkeys, while administrators control anonymous access and monitor Prometheus metrics.

Pastefy gives developers a self-hosted pastebin and GitHub Gist workspace where multi-file code snippets, Mermaid architecture diagrams, and terminal recordings can be shared in a single click or cURL command. Its multi-tab editor highlights syntax across more than 200 programming languages so you can bundle scripts, configuration files, and documentation inside one URL. Markdown notes render cleanly. SVG graphics, CSV tables, GeoJSON maps, unified diffs, calendar events, regex testers, and Asciinema `.cast` terminal sessions all preview interactively in the browser. Sensitive snippets stay locked behind client-side AES password encryption, automatic expiration timers, and public, unlisted, or private visibility controls. Authenticated users organize pastes into nested folders, fork community snippets, generate QR codes or styled code screenshots, and embed interactive viewers into external docs. Command-line users pipe output directly via `curl -F [email protected]`, manage pastes from VS Code or Raycast extensions, and automate workflows through the REST API v2 with official JavaScript, Java, and Go SDKs. Single sign-on supports GitHub, Google, Discord, Twitch, and custom OpenID Connect providers.

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.

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.

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.

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.

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.

015 is a send-it-and-forget-it file sharing service for files that should exist for hours, not forever. Drop in a large file and it uploads in chunks, resuming where it stopped if the connection drops, while a short pickup code and a share link give the recipient two easy ways to collect it. If the same file was uploaded before, its hash gives it away and the transfer completes instantly without moving the data again. Every share carries your rules: an expiration time, a password, and a download count limit, enforced by signed download tokens so a shared link cannot be passed around indefinitely. Uploaded images can be compressed or converted in the background while you keep working, and text snippets share through the same expiring-link system when a file is overkill. Images and videos preview in the browser before downloading, and email or webhook notifications can tell you when a share is picked up. The interface speaks seven languages and answers just as well on a phone as on a desktop. When the window closes, a daily janitor sweeps expired files off the disk, so the server never quietly fills with forgotten uploads. 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.

The functions, config files, and one-liners you keep re-deriving finally get a searchable home: ByteStash is a self-hosted code snippet manager - a private Gist. Each snippet holds multiple code fragments, so a Docker Compose file, its .env template, and a plaintext usage note live together under one titled, categorized entry. Monaco-based syntax highlighting covers dozens of languages, from Python, TypeScript, Go, and Rust to YAML, Dockerfiles, Terraform, and Markdown. Retrieval is the point: filter by language or category, search titles and descriptions, and optionally include snippet contents in full-text search. Snippets can be pinned for quick access and shared via public links that recipients open without an account. Multi-user support runs on JWT authentication with optional OIDC single sign-on for teams on centralized identity, and a full CRUD REST API with Swagger documentation wires snippet retrieval into editors, scripts, and CI pipelines. Storage is a single SQLite database with optional encryption, and collections export as JSON or Markdown. A React frontend on a Node.js backend, deployed as one lightweight container.

Real-time collaborative Markdown behind your own firewall: HedgeDoc (formerly CodiMD, descended from HackMD's open-source edition) keeps team notes on team infrastructure. Share a note's URL and collaborators are editing together instantly - live cursors, changes appearing keystroke by keystroke - in a three-mode interface that toggles between raw Markdown, rendered preview, and side-by-side split. The Markdown dialect is extended where engineers need it: Mermaid, Graphviz, and Vega-Lite diagrams, MathJax for equations, syntax-highlighted code blocks, embedded content, and a presentation mode that turns a note into reveal.js slides with a single YAML header. A dropdown permission system controls each note - freely editable, limited to signed-in users, or locked read-only - and published notes become clean read-only pages for wider distribution. Revisions track every change with the ability to revert to any earlier version. The AGPL-3.0 codebase is light enough to run on a Raspberry Pi and deploys via Docker with PostgreSQL, MySQL, or SQLite. Authentication covers LDAP, SAML, OAuth2, and email. It deliberately stays a focused document editor - no page trees or kanban - and does that one job with excellent keyboard-first ergonomics for meeting notes, RFCs, runbooks, and shared scratchpads.
