Open Source App Cloud Marketplace

Live web search plus an LLM of your choice: Farfalle is an open-source, self-hosted answer engine in the Perplexity mold. Queries route through one of several search providers - self-hosted SearXNG for a fully independent stack, or Tavily, Serper, and Bing APIs - and the model composes a cited answer from the retrieved results. Model flexibility is the core design: run llama3, mistral, gemma, or phi3 locally through Ollama for zero per-query cost and full privacy, use cloud models like GPT-4o or Groq-hosted Llama 3 for speed, or route to any provider via LiteLLM. An Expert Search mode uses an agent that plans a multi-step search strategy and executes it for harder questions, and chat history keeps prior research sessions available. The stack is a Next.js and shadcn/ui frontend over a FastAPI backend with Redis rate limiting, shipped as a pre-built Docker image. A browser search-engine entry pointing at your instance makes it the default search from the address bar. Paired with SearXNG and Ollama, the whole pipeline runs with no external API at all.

Page views, referrers, browsers, and screen sizes - Ackee delivers the analytics developers actually check, from a deliberately minimal Node.js and MongoDB stack that skips both Matomo's weight and Google Analytics' cloud dependency. Its defining constraint is anonymization: no cookies, no unique user tracking, and a multi-step anonymization process that keeps visitors unidentifiable while the aggregate numbers stay useful. In its default anonymous mode Ackee collects no personally identifiable information at all, which means GDPR and CCPA compliance out of the box and no cookie consent banner on your sites. A detailed mode adds screen size, language, and per-visit referrers - still without cookies or fingerprinting. Integration mirrors the Google Analytics pattern: create a domain in settings, drop the generated ackee-tracker snippet into your pages, and data appears in a clean single-page dashboard. One instance tracks multiple domains, and custom events capture button clicks, signups, and conversions. The distinctive engineering choice is the fully documented GraphQL API: everything the dashboard shows comes from that API, so you can query active visitors, average duration, and view statistics programmatically, feed data in from apps and services beyond websites, or build an entirely custom interface on top. If you want bare-minimum analytics with a real API and zero privacy anxiety, this is the tool.

Plex's own dashboard shows current streams and forgets everything else - which is why every Plex server admin eventually installs Tautulli, the analytics layer. This Python web application (descended from PlexWatch and Headphones) logs complete watch history - what was watched, who watched it, when, where, from which device and IP, and whether it played directly or transcoded - and turns it into clean Highcharts graphs of daily plays, concurrent streams, bandwidth, and platform breakdowns. The home page surfaces top statistics over configurable windows: most-watched content, most active users, stream type ratios. For running a server shared with family and friends, this is operational truth: spot the user forcing 4K transcodes on a phone, see which libraries earn their disk space, and track sync activity across users. The notification engine triggers on server events - playback starts, transcode decision changes, recently added media, server down - through dozens of agents (Discord, Telegram, Slack, email, webhooks) with fully customizable text and conditions, plus arbitrary script execution. Scheduled newsletters email your users a styled digest of recently added content. A comprehensive API exposes every statistic for dashboards like Homarr, and an official mobile app monitors activity on the go. Themed to match Plex/Web. GPL-licensed.

With over 7,500 GitHub stars and 140 contributors, Matterbridge is the Go-powered chat bridge that connects over 20 messaging platforms through a single TOML configuration file, letting teams communicate across platform boundaries without forcing anyone to switch applications. The gateway architecture routes messages bidirectionally between any combination of Discord, Slack, Telegram, Matrix, IRC, Mattermost, Microsoft Teams, XMPP, Rocket.Chat, Nextcloud Talk, Keybase, Mumble, Twitch, WhatsApp, VK, Gitter, Zulip, ssh-chat, and Harmony, with transparent username and avatar spoofing so bridged messages appear native on each platform. Message edits and deletes propagate across bridges, file attachments and inline images transfer between protocols, threading and reply context is preserved where platforms support it, and private group bridging enables confidential cross-platform conversations. Multiple independent gateways can run simultaneously, each bridging different channel sets with different protocol combinations. The REST API enables third-party integrations and custom bridges without modifying the Matterbridge codebase, while the tengo scripting engine allows inline message transformation and filtering. Game chat support bridges Minecraft and Counter-Strike server chat into messaging platforms. Deployment runs as a single static Go binary with zero dependencies, or as the official Docker image with the configuration file mounted as a volume. 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.

Personal, minimalist, database-free bookmarking - Shaarli is a philosophy as much as an app. Everything lives in a single compressed datastore file inside data/: no MySQL, no PostgreSQL, backup by copying one directory. That write-once/read-many file is usually served straight from OS disk caches, which is why a decade-old Shaarli instance with tens of thousands of links still responds instantly. Designed deliberately single-user, it saves URL, title, unlimited-length description, and tags (with autocomplete, renaming, and merging), marks entries public or private, and automatically strips utm_source and fb tracking parameters from saved URLs. That description field is why the community uses Shaarli as far more than bookmarks: a microblog, read-it-later queue, code-snippet base, pastebin, and shared clipboard between machines. Sharing is one click via bookmarklet or Android apps; consumption is per-tag RSS/Atom feeds plus a daily digest feed; search is full-text with tag filtering. A REST API opens it to any client, a plugin and theme system extends the PHP core (Markdown rendering, thumbnails), and import/export uses browser-standard Netscape HTML - your data enters and leaves freely. LDAP login is supported, no telemetry is sent anywhere, and the UI degrades gracefully without JavaScript. The anti-cloud Delicious.

Receipts, contracts, and letters that arrive as pixels rather than text: Papermerge is a document management system built specifically for scanned documents. Upload a PDF, TIFF, JPEG, or PNG and OCR runs automatically, with a real-time status indicator beside the document title; under the hood it drives OCRmyPDF and Tesseract, supporting 130+ languages and producing a new document version with a selectable, searchable text layer you can download. Full-text search runs across everything, with multiple search-engine backends (Xapian by default). The interface deliberately mimics a modern desktop file browser: dual-panel commander, drag and drop, hierarchical folders, and colored tags on documents and folders. Page management fixes what scanners get wrong - delete blank pages, rotate, reorder, merge, extract, and move strayed pages between documents, powered by PikePDF. Document types act as categories, each with its own custom metadata fields, so invoices carry vendor and amount while contracts carry parties and dates. Versioning preserves every state of a document. Multi-user support includes groups, group ownership, permission management, and document/folder sharing between users and groups, and an OpenAPI-compliant REST API automates ingestion from scanners or scripts. Apache-licensed, ideal for long-term digital archives.

A minimal Ubuntu 24.04 LTS virtual private server — no pre-installed applications, no opinionated configuration, just the operating system and root access. Start from a clean slate and install exactly what you need: web servers, databases, development toolchains, CI runners, monitoring stacks, VPN endpoints, game servers, or anything else that runs on Linux. The server ships with apt package management, systemd service supervision, and standard networking configured out of the box, giving you access to over 36,000 packages in the Universe repository alone. Connect via SSH with the key you select during deployment; a dedicated IPv4 address is included with every server at no extra charge. A browser-based serial console in the RepoCloud dashboard provides emergency access without an SSH client. Snapshots let you capture the server state before risky changes and roll back with one click. Resize CPU and RAM on demand without reinstalling. Canonical's standard security maintenance covers this LTS release through May 2029 — five years of patches for the Main repository. Ubuntu Pro extends that to ten years with additional Universe coverage, kernel livepatching, and compliance tooling, available free for up to five machines.

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.

The moment after ShadowPlay saves a great clip is what Fireshare was built for: your friends see it now, not after a YouTube upload, processing queue, and platform terms review. Drop videos into a watched folder and this Flask/React application generates a unique shareable URL for each one, complete with Open Graph metadata - so pasting the link into Discord, Twitter, or Slack produces a proper embed with title, description, and video thumbnail instead of a raw URL. Viewers need no account and no app. Visibility is per-file: public (browseable on your feed), private (unlisted, reachable only by direct link), or password protected. For game clips specifically, Fireshare organizes automatically - clips sort by game with cover art pulled from SteamGridDB, no manual tagging - while tags and full-library search cover everything else. Optional transcoding (CPU or GPU) creates lower-quality renditions so viewers on weak connections get automatic quality adaptation, and video cropping trims clips in place. The extras round out a genuinely finished tool: view counters, timestamped share links, a shuffle button, restrictable uploads, Discord notifications for new videos, an RSS feed of the public feed, mobile support, and LDAP for multi-user setups. No storage limits, no watermarks, no platform deciding what stays up. GPL-licensed.

With nearly 3,900 GitHub stars, over 1,800 forks, and continuous development since 2013 culminating in the v1.18.4 release in June 2026, osTicket remains one of the most deployed open-source help desk systems worldwide, trusted by organizations from small businesses to universities and government agencies. The PHP backend on Apache or IIS with MySQL stores every ticket, response, and attachment while the web interface provides separate agent and customer portal views with role-based access control across departments, teams, and individual agents. Customers submit tickets through web forms, email piping, or phone-entry by agents, and configurable ticket filters automatically route incoming requests to the correct department, assign agents or teams, set priority levels, apply SLA plans, and trigger canned responses based on matching criteria including custom field values. Agent collision avoidance locks tickets during response composition to prevent duplicate replies, while SLA plans with business hour schedules track due dates and escalate overdue tickets automatically. Custom forms and fields let organizations capture structured data specific to each help topic — from IT asset tags to billing account numbers — with configurable required and internal-only visibility. The advanced search system with saved queries and CSV export enables reporting across all ticket metadata and custom fields. The customer portal provides ticket tracking, profile management, and knowledge base access. OAuth2 plugin support enables modern email authentication with Microsoft 365 and Google. 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 licensed.

Writing docs should feel like editing a modern document, not wrangling Markdown files - CodeX Docs delivers that on Editor.js, the block-styled editor its CodeX team builds and thousands of products use. Content is composed from clean blocks (headings, lists, code, images, embeds) with a UI that reads well on both desktop and mobile, and pages render statically with human-readable, SEO-friendly URLs. Structure is free-form: pages nest to any depth, so a flat FAQ and a deep product manual coexist in one instance, and the UI tunes to fit - collapse sections, hide the sidebar. The operational footprint is deliberately tiny. No database is required: the default driver persists to a local folder, with MongoDB available when you want it, and the whole app configures through one YAML file (overridable with APP_CONFIG_ environment variables) covering title, start page, auth password, and JWT secret. Editing mode sits behind password authentication. Thoughtful extras are wired in: readers can report misprints straight to your Telegram or Slack, Hawk error tracking catches frontend and backend exceptions, and Yandex Metrica analytics is a one-line config. A ready-made Helm chart covers Kubernetes. Written in TypeScript.

When Commento's original maintainer went quiet, Commento++ bundled the community's bug fixes and stalled merge requests into a batteries-included release of the beloved Go-based Disqus alternative - and kept building. The core promise is unchanged: an embeddable comments box that is orders of magnitude lighter and faster than Disqus, with no ads, tracking, or data sales - two lines of HTML and a PostgreSQL database. On top of Markdown comments, voting, Disqus import, OAuth login (Google, GitHub, Twitter) plus SSO, sticky comments, thread locking, and email notifications, the fork's additions are substantial: WebSocket-powered live comment updates with permalinks and highlight animations for new arrivals, guest commenting with a name, a cross-domain moderation dashboard for approving and deleting comments in one place, MathJax rendering support, wildcard domain matching, a reInit hook that makes single-page-application integration clean, and Perspective API spam scoring alongside the existing Akismet integration. Optional page-view logging graphs traffic on the dashboard, native SSL termination works without a proxy, and script-tag data attributes control fonts, CSS overrides, deleted-comment visibility, and polling-versus-WebSocket behavior.

"Stupid simple software" is the entire philosophy at DumbWare.io, and DumbBudget delivers it: no over-engineering, no complexity, no accounts, no bank connections - just a clean, modern ledger for money in and money out. Log income and expenses, assign categories, and watch real-time balance calculations update as you type. Finding transactions is quick: filter by type, narrow by date range, sort by date or amount. When tax season or spreadsheet analysis calls, everything exports to CSV. Access control matches the philosophy - a single PIN (set via one environment variable) gates the app, backed by real security engineering: rate limiting on PIN attempts, temporary lockout after failures, secure session handling, and no sensitive data in browser storage. Multi-currency support covers the ISO codes, and a SITE_TITLE variable names each instance - deliberately useful, because running separate instances per account or family member is the intended pattern for multi-user needs. The responsive UI ships light and dark themes and installs as a PWA on phones, where expense logging actually happens. Configuration is five environment variables; data persists in one folder. If Actual Budget and Firefly III feel like accounting software, this is the notepad that gets used. GPL-licensed.

Bring your own API keys and work with OpenAI GPT models, Anthropic Claude, Google Gemini, Mistral, DeepSeek, Grok, Azure endpoints, and local models in one organized workspace: TypingMind is a unified chat frontend for large language models, replacing a browser tab per provider. Parallel chat sends the same prompt to multiple models and compares answers side by side, and models can be switched mid-conversation. A prompt library stores reusable, tagged prompts with variables, and the AI Agents system builds specialized assistants that bundle a base model, custom instructions, assigned plugins, and uploaded knowledge files for RAG. Plugins extend every connected model with web search, image generation (DALL-E, Stable Diffusion), Deep Research, URL reading via Firecrawl, and Zapier automation - plus MCP server integrations for Notion, Atlassian, and other external tools, and a JavaScript extension API for custom behavior. Chats store locally by default with optional sync. Self-hosting puts the interface on your own domain and, for teams, adds branding, member access limits, and shared prompt and agent libraries.

Where Miniflux strips reading down, FreshRSS gives you knobs - the feature-rich pole of self-hosted RSS, comfortable with thousands of feeds. It's a multi-user PHP aggregator (host family and friends on one instance, with an anonymous reading mode) with the reading workflow refined over a decade: favorites, custom tags, powerful filter and search queries, three reading views, and statistics that reveal each site's publishing frequency - useful for pruning subscriptions. Two properties make it the standard choice. First, the Google Reader-compatible API (plus a Fever API) syncs with virtually every serious RSS client - Reeder, NetNewsWire, ReadYou, FeedMe, Fluent Reader - so your phone reads from your server. Second, native WebSub support means compatible sources (WordPress, Blogger, Medium, Friendica) push new articles instantly instead of waiting for polling. A 50+ extension ecosystem adds what truncated feeds omit - full-text content fetching, reading-time estimates, trending views, auto-unsubscribe for dead feeds - alongside community themes and custom CSS. OPML import/export keeps subscriptions portable, a CLI handles administration, and article sharing posts to many services. AGPL-licensed, running on SQLite, MySQL, or PostgreSQL. Feedly Pro's feature set, minus Feedly's subscription and its algorithms.

Feature requests, bug reports, upvotes, and a public roadmap: Astuto (Ruby on Rails backend, React frontend) gives users a Canny-style feedback portal so product decisions rest on visible demand rather than the loudest voice in the room. Feedback organizes into as many boards as you want (features, bugs, integrations), each post carrying a custom status you define - "planned," "in progress," "shipped," or whatever matches your process - and those statuses feed a public roadmap view showing users what is actually being worked on. Participation friction is adjustable at both ends: sign-in works with plain email or any OAuth2 provider, anonymous feedback can be enabled for unregistered users, and a moderation queue lets you approve posts before they appear when spam is a concern. Integration hooks are practical rather than sprawling - webhooks fire on events to connect Jira, Trello, or Slack, and a REST API manages the whole feedback space programmatically. Brand customization, an invitation system, private-site settings, and recap emails for administrators complete a deliberately minimal tool: it collects, organizes, and prioritizes feedback well, for free, forever.

A free, polished web client for Subsonic-compatible music servers: Substreamer is the browser-based frontend you point at your existing streaming backend to play your own library from anywhere. It speaks the Subsonic API (v1.13 and higher), which makes it compatible with the whole ecosystem that has grown around that protocol: the original Subsonic server, its forks Airsonic and Madsonic, and modern implementations like Navidrome and Ampache. That decoupling is the point - your music files, transcoding, and library indexing live on whichever server you prefer, while Substreamer provides the listening experience: browse by artist, album, and genre, build and manage playlists, search your collection, and stream on demand. This RepoCloud deployment runs the containerized web edition, so the same interface is available from any browser without installing a native app, and it pairs with the Substreamer mobile apps that made the client popular. For anyone assembling a self-hosted Spotify replacement - typically Navidrome for the backend plus a good client - Substreamer fills the client half with a clean, familiar player UI. Because it is a stateless client, the container is lightweight and low-maintenance: connect it to your server's URL and credentials, and your entire collection is streaming in minutes, with no subscription and no catalog that can disappear.

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.
