Open Source App Cloud Marketplace

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.

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.

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.

Point the gh CLI at your private Githome server and it works identically to github.com, because every REST v3 and GraphQL v4 endpoint returns byte-for-byte compatible JSON shapes, headers, Link pagination, and ETag caching. A single compiled Go binary serves the REST API under /api/v3, GraphQL under /api/graphql, git smart-HTTP transport, and a server-rendered web UI implementing the GitHub Primer design system with full functionality when JavaScript is disabled. The web interface provides repository browsing with Markdown rendering and syntax highlighting, issue tracking, pull requests with unified diffs and inline code review threads, full-text search, user profiles, and a notifications inbox. Authentication supports personal access tokens with prefix-based identification, OAuth device and web flows, and scoped permissions on every response header with only token hashes stored. The pull request system implements the complete lifecycle including async mergeable state computation, squash, merge, and rebase strategies, commit statuses, check runs, and statusCheckRollup fields. Webhooks deliver events with X-Hub-Signature-256 verification, SSRF protection, and at-least-once retry semantics. Storage supports SQLite for single-node deployments or PostgreSQL for production configurations. Performance optimizations include batch loaders replacing N+1 queries, keyset pagination, FTS-backed search, and GraphQL dataloaders. Docker deployment pulls the official multi-arch container image from GitHub Container Registry.

Email discussion lists - the venerable listserv pattern where one address relays to a whole group - without the notorious setup pain of Mailman or Sympa: that is Gray Duck Mail. Its architectural trick is requiring no mail server of your own: the C#/ASP.NET Core app monitors a POP3 inbox at any external email host supporting POP3/SMTP and aliasing, relays each incoming message to all list members via SMTP, and archives it for browsing in the web interface. Replies route back to the entire group automatically. The tedious parts of list management are handled by convention: dedicated aliases process join requests, subscription confirmations, and unsubscribes, while a bounce alias in the return-path catches delivery failures so dead addresses get handled instead of silently rotting. The web administration interface creates and removes lists, manages contacts, browses message archives, and imports or exports the local database for backup. GPLv3-licensed, Docker-distributed, and fully code-documented, it targets exactly the groups email still serves best - neighborhoods, schools, congregations, workplaces, and families - where one message keeping everyone in the loop beats yet another app nobody wants to install.

Newspipe gives a team or a household its own feed reader that nobody can shut down. Subscribe to any RSS or Atom source, sort feeds into categories, and read articles in a three-column view with the list in the middle and the full text on the right. Tabs filter unread, read, liked, and read-later items, stars mark favorites, and search finds anything already stored. Notes can be attached to any article and reviewed on a dedicated page. A history page charts how many articles arrived each year, and the inactive feed report flags sources that went quiet. Bookmarks have their own manager with a Pinboard importer and public listings. A single instance serves many users, and administrators create accounts and trigger fetches from an admin area. Feeds import and export as OPML, whole accounts move as JSON, and an API lets scripts manage subscriptions or plug in a custom crawler. The interface speaks English, French, and German, switches between light and dark themes, and can authenticate against LDAP. A scheduled command fetches new articles automatically. 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.

A DuckDB file is fast, but sharing one across a team usually means passing it around by hand. WebDuck puts DuckDB behind a server, so analysts and applications reach the same databases through a REST API or a dark amber web interface. Projects group databases, and each database can carry its own API password with read, write, or admin access levels. The dashboard shows server status, a live view of incoming REST traffic, and storage use. A browse view offers tree navigation, infinite scroll, and inline cell editing. The SQL editor runs multi-statement scripts, keeps a query history, accepts Alt+Enter to execute, and can load a whole SQL file. Import and export handle CSV, Parquet, and JSON up to 256 MB. Deleted databases move to a trash where they can be restored. Per-database write protection and a compression action keep files safe and small. Administrators sign in with bcrypt-hashed passwords and JWT tokens, and the interface ships in English and German. Setup comes through Docker, pip, or a YAML file, and a small command line initializes the server, adds users, and reports status.

Picking a meeting time for six people usually takes forty messages, and Timeful replaces them with one link. Create an event, choose a date range or days of the week, and share the URL; guests do not need an account. Each person drags across a time grid to mark what works, and the combined heatmap reveals the overlap at a glance. Times can be marked as available or only if needed, and a best-times toggle highlights the slots that suit the most people. Calendar autofill pulls busy blocks from Google, Apple, Outlook, or an ICS feed so nobody retypes their week. Time zones convert automatically for distributed teams. Event owners can hide responses from other guests, duplicate polls for recurring meetings, export availability as a CSV, and schedule the final slot straight into a Google Calendar event. Availability groups keep a team's live calendar overlap on a single page, and reminder emails go out to attendees on the day of the event. A plugin API lets browser extensions read and write availability. The interface is a calm green grid with no clutter.

Passwords pasted into chat live forever, but a Cryptgeon note vanishes the moment it has been read. You type a note or pick a file, press create, and get a share link with a QR code to hand over. Encryption happens in the browser with XChaCha20-Poly1305, so the server holds only ciphertext and never sees the key that sits after the hash in the link. Advanced options set the number of views or a lifetime in minutes, and a custom password can be required on top of the generated key. Everything is kept in memory in a Valkey or Redis cache, so nothing is written to disk. Operators tune limits with environment variables for note size, maximum views, maximum expiration, file uploads, and ID length. The interface is a calm monospace page with dark and light themes. A command-line client sends notes from a terminal, and a Raycast extension covers the macOS launcher. Theme text, logo, favicon, and an imprint page can be customized to match a team or company. A health endpoint reports status to proxies and orchestrators. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

A bookmark bar that also knows if your homelab is on fire is the pitch behind nextDash. Links live on pages and categories with tags, notes, an inbox for unsorted finds, and one search panel for bookmarks, commands, and containers. Mark any link as Monitor and the server checks it every few minutes, keeping 30 days of uptime, certificate and domain expiry dates, and drift warnings, with alerts to ntfy, Slack, Discord, Telegram, Gotify, Apprise, or a phone push. A Containers view lists every Docker container with logs, start, stop, and update with automatic rollback, each matched to its bookmark. Dashboard widgets cover weather, feeds, CPU, memory, disks, Unraid, Jellyfin, Plex, Sonarr, Radarr, qBittorrent, and Home Assistant. A theme studio offers 390 themes and 267 backdrops in six languages, and an optional assistant answers in plain words when you switch it on. Imports arrive from every browser, Pocket, Raindrop, and linkding, and automatic backups with a 30-day trash protect the collection. The weekly digest sums up broken links, expiring certificates, and pending container updates.

Scan a barcode, press Enter, and the sale is done: that is the whole rhythm of NodeDR POS at a shop counter. A USB scanner works, and so does a phone or tablet camera. Each sale can carry tax breakdowns with GSTIN and HSN codes, percentage or flat discounts, loyalty points, store credit, and customer dues for short payments. Cash, UPI with a payment QR, and card are supported in more than 20 currencies. Receipts print through the browser, download as PDF, or go straight to a USB thermal printer. Inventory takes bulk CSV or Excel imports, generates printable EAN-13 barcode labels, looks up unknown barcodes in free product databases, and flags low stock. Purchasing adds suppliers, purchase orders, and reorder suggestions. Orders from WooCommerce, Shopify, or a custom site flow through a New, Packing, Ready, and Collected board. Phone and laptop sellers can switch on IMEI tracking with warranty lookup. A customer display shows the live cart on a second screen. Reports cover revenue, gross profit, average bill, category mix, and busy hours, with staff roles and A4 tax invoices alongside.

UptimeKit watches your services from several regions at once and publishes the verdict on a status page your customers can actually read. A central dashboard assigns checks to worker probes that run them on schedule, covering HTTP and HTTPS, TCP, ICMP ping, DNS, keyword matches, and JSON responses. Monitors are sorted into nested groups and tags, and HTTPS targets get automatic certificate expiry tracking. When something breaks, an incident takes shape with severity, status transitions, comments, and a resolution flow, either from the dashboard or from a Prometheus AlertManager alert. Status pages come in multiple flavors: public, password protected, or tied to a custom domain, with themes, uptime history bars, and email subscribers who hear about every update. Notifications reach Discord, Google Chat, Telegram, ntfy, Apprise, and plain webhooks. Organizations with roles keep several teams in one installation, and OIDC single sign-on connects the login to an existing identity provider. Response time charts break latency into percentiles per region over any period you pick. A planned maintenance window announces itself on the status page before it begins.

Teams that juggle a file drive, a chat app, a task tracker, and a dashboard tool can fold all four into one self-hosted workspace. Twigex stores files on local disk or S3-compatible storage, shares them with users, groups, or public read-only links, and opens office documents in EuroOffice or Collabora for simultaneous editing. Chat offers channels and direct messages with reactions, mentions, and link previews. Video calls and scheduled meetings run through LiveKit, and guests can join a channel by link. Projects organize work as tables of tasks with custom fields and subtasks, viewable as a grid, kanban board, Gantt timeline, or calendar. Collimato, the analytics module, connects to databases and APIs, models the data, and builds charts and dashboards with filters and KPI cards. The admin area covers users, groups, roles, storage backends, SMTP, office editing, and security settings. The Community Edition is free to run from one binary, a Docker Compose stack, or a Helm chart on Kubernetes.

Gold foil covers the whole planet until you click a country, and then it scratches away to grey, which is the whole charm of Scratch Map. A world map lists every UN member state plus selected territories, and region maps cover the United States, Canada, Australia, France, Mexico, Japan, Spain, the United Kingdom, Germany, New Zealand, Brazil, China, India, and Italy. Each click opens a prompt where you can record the year you visited and paste a link to your photo album, and clicking again updates the details or unscratches the place. Maps zoom with the mouse wheel or on-screen buttons, pan by dragging, fit to the screen on demand, and go fullscreen. The home page shows thumbnails of every map with expandable tables that separate visited places from those still waiting, with years and clickable album links. A Share button can expose a read-only view of any map when the optional sharing flag is on. Everything lives in a single JSON file in a data folder, so backups are a simple copy. A Docker health check keeps container platforms informed, and the port, address, data directory, and log level are set with environment variables.

Taking notes and publishing a website usually need two different tools, but W treats them as the same act. Every page you create gets its own address, and a privacy level marks it public, private, or not yet published. The editor offers tabs for Markdown content, CSS, a custom body template, and JavaScript, with a metadata panel for title, description, tags, date, and authors. Home view lists every page with sorting, filters, search, and saved bookmarks for common queries. Two alternative views draw pages as a link graph and, for pages with coordinates, as markers on a map. A media manager organizes uploads in folders, offers a thumbnail gallery, and can optimize images for the web. Several users can work together with reader, editor, super editor, and admin roles, and optional LDAP sign-in is available in beta. Templates share layouts across pages, URL commands like add and edit speed up navigation, and an experimental API opens the data to scripts. Pages keep working even with JavaScript turned off. Everything is stored in plain files, so no database server is needed. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

GlitchTip speaks Sentry's protocol without Sentry's operational weight - open-source error tracking that your existing SDKs already understand. The pitch is pragmatic: instrument your application with the official Sentry SDKs you already know - any language they cover - and point the DSN at your own GlitchTip instance instead. Errors, exceptions, log messages, and Content Security Policy violations flow into one place for triage, grouped into issues with stack traces, with alerts delivered by email or webhook the moment things break. Where self-hosted Sentry has ballooned into a docker-compose stack of twenty-plus containers, GlitchTip is a deliberately lean Django and PostgreSQL application a small team can actually run. Beyond errors, it bundles three more monitoring concerns: performance monitoring takes a works-out-of-the-box approach - no dashboard building, just your slowest web requests, database queries, and transactions surfaced automatically; uptime monitoring pings your sites and alerts on failures, or runs in reverse as a dead-man's-switch heartbeat for cron jobs that must check in on schedule; and log search puts application logs alongside errors for faster debugging.
