Postiz
Powering over $145K monthly recurring revenue as a one-person company and holding 34,000+ GitHub stars, Postiz has emerged as the most widely adopted open-source alternative to Buffer, Hootsuite, and Hypefury — combining social media scheduling with AI-driven content creation and agentic automation in a single self-hosted platform. The Next.js 14 frontend with React 18 and Tailwind CSS delivers a visual calendar and Canva-like design editor, while the NestJS backend orchestrates publishing across 30+ social networks including X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Pinterest, Threads, Dribbble, Discord, Bluesky, Mastodon, and Facebook. Temporal handles durable workflow execution for reliable scheduled posting, retry logic, and background job processing. The built-in AI assistant generates post ideas, captions, hashtags, images, and short videos from natural language prompts — all within a single chat interface. An agentic layer exposes a CLI and MCP server that allow AI agents like OpenClaw, Claude, and ChatGPT to autonomously plan, draft, and schedule posts programmatically. Team collaboration includes role-based permissions, approval workflows, multi-workspace management for agencies, and commenting on scheduled content. A full REST API with a NodeJS SDK, N8N custom nodes, and Make.com integration enables automation pipelines. Analytics track engagement, reach, and growth across all connected accounts from a unified dashboard. The self-hosted stack deploys via Docker Compose with PostgreSQL, Redis, and Temporal pre-wired — no feature limitations compared to the cloud version. 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.
LearnHouse
LearnHouse delivers a modern open-source learning platform that replaces proprietary course builders with a self-hosted alternative shipping a rich feature set out of the box. The Tiptap-powered block editor supports videos, documents, embeds, quizzes, and file uploads in a Notion-like interface with real-time co-editing powered by Hocuspocus and Yjs CRDT synchronization over WebSocket. AI tutoring integrates Google Gemini and LlamaIndex for RAG-powered context-aware assistance that adapts to course content, while interactive Playgrounds use AI to generate simulations, diagrams, and learning exercises. The platform handles the full course lifecycle: chapters and activities organize into collections and learning paths, assignments support automated and manual grading, and code blocks execute student submissions in 30+ languages with auto-grading. Analytics dashboards track learner engagement, progress, and completion rates in real time. The backend runs on FastAPI with SQLModel and Alembic migrations against PostgreSQL 16 with pgvector for AI embeddings, while Redis handles caching and session management. The frontend builds on Next.js 16 with React 19 and Tailwind CSS v4. Deployment uses an interactive CLI wizard that configures domain, database, admin account, SSL via Let's Encrypt, and optional features like email via Resend, S3 storage, and Google OAuth, then generates a Docker Compose stack ready to start. On RepoCloud, deploy LearnHouse on a dedicated VPS with root SSH access, persistent PostgreSQL storage for your course data, and complete control over AI provider keys and branding customization, all under the AGPL v3 license.
Orchard Core
Content types, media libraries, workflows, roles, search, and a GraphQL API all ship in the box with Orchard Core, a free CMS and application framework that hosts many separate websites from one install. Editors build content types in the admin by combining parts and fields, with no migrations to write, and preview an item live before publishing it. Designers adjust page HTML safely with Liquid templates, and developers add their own modules. Multi-tenancy runs many isolated sites from one deployment, each with its own content, users, settings, and theme, and a setup screen lets you pick a recipe and database for each site. Media uploads can be resized on the fly and stored on remote providers, and a visual workflow editor automates content approvals, webhooks, and form submissions. A typed GraphQL API feeds headless sites and single-page applications, and custom SQL or Lucene queries can be exposed as endpoints. Roles and fine-grained permissions decide who can do what, OpenID Connect handles external sign-in, and two-factor authentication protects accounts. Content and the admin interface can be localized, and deployment plans move content and configuration from staging to production. SQLite works out of the box, SQL Server, MySQL, MariaDB, or PostgreSQL can be chosen at setup, and the official Docker image starts a site with one command. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. BSD-3-Clause licensed.
Seanime
Seanime turns your server into a dedicated anime and manga command center, combining local library management, torrent streaming, an integrated manga reader, and AniList progress tracking in a single self-hosted web application. Point it at your media folders and the smart scanner automatically identifies and matches your anime files to AniList entries without requiring strict naming conventions or folder hierarchies. Stream episodes directly from torrents through qBittorrent, Transmission, Torbox, Real-Debrid, AllDebrid, or Premiumize; the built-in player starts playback before the download finishes, so there is no waiting for full transfers. The manga reader pulls chapters from community extension sources and tracks your reading progress across series automatically. An in-app extension marketplace lets you install third-party providers for streaming, manga, and torrent sources, all written in JavaScript and managed through a visual interface. Seanime Tenji, the companion mobile app for iOS and Android, connects to your server for on-the-go library browsing, content streaming, and offline downloads. Auto-download rules grab new episodes of airing series the moment torrents appear. The transcoding engine handles on-the-fly conversion for browser playback on any device, while direct play passes through compatible formats at full quality. 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.
Karakeep
Previously known as Hoarder and now holding 28,000+ GitHub stars, Karakeep is the most popular open-source bookmark-everything application — combining AI-powered automatic tagging with full-text search, page archival, and cross-platform access for digital content hoarders who refuse to let valuable links disappear. The Next.js frontend with tRPC communication delivers a responsive interface for saving links, notes, images, and PDFs, while Puppeteer crawls bookmarked pages to fetch titles, descriptions, and images automatically. LLM-based auto-tagging supports OpenAI, Anthropic, or local models via Ollama for privacy-first deployments that never send data to external services. Meilisearch powers full-text and semantic search across all stored content including OCR-extracted text from images. A rule-based automation engine triggers custom actions based on bookmark properties — automatically sorting, tagging, or archiving content matching defined conditions. Full page archival via Monolith preserves complete page snapshots against link rot, while yt-dlp integration archives videos from YouTube and other platforms. RSS feed ingestion automatically captures new articles from subscribed sources. Collaborative lists enable teams to build shared bookmark collections, with per-list permissions and real-time sync. Native iOS and Android apps, Chrome and Firefox extensions, and browser bookmark sync via Floccus ensure capture from any device. Importers migrate data from Chrome, Pocket, Linkwarden, Omnivore, and Tab Session Manager. 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.
Halo
Halo is a modern CMS that handles blogs, knowledge bases, corporate sites, and full e-commerce storefronts from a single installation, distinguished by a polyglot plugin architecture that runs both Java and JavaScript extensions on a GraalVM runtime. Built on Spring Boot 3 with a Vue.js admin console, the platform delivers a clean content management experience with Markdown and rich-text editing, live preview, scheduled publishing, draft management, media uploads, and granular multi-user role-based access controls. Plugins can be enabled or disabled at runtime without restarting the server, and the official marketplace offers over 100 free themes plus a growing library of extensions covering SEO optimization, search integration, paid content access, AI writing assistance, and Q&A chatbots. Storage backends are configurable through plugins, supporting local disk, S3-compatible object storage, and other providers. The fully documented RESTful API enables headless CMS usage for decoupled frontend architectures. Database support includes embedded H2 for quick starts, with production deployments on PostgreSQL or MySQL. Nearly 40,000 GitHub stars and over 2.5 million Docker pulls reflect the project's maturity and active development pace. A single Docker command gets a functional instance running on port 8090. 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.
TYPO3
TYPO3 lets an organization run any number of multilingual websites from one installation, with editors working in a page tree and administrators deciding who may touch what. Editing happens in a context panel that slides in beside the page layout, and a guided wizard creates new pages step by step. Translations can be copied or connected to their source with change tracking, and sites can mix languages, including right-to-left scripts. Workspaces keep edits away from the live site until they are previewed and approved, while access lists, page permissions, and mounts control which parts of the tree each backend user may change. Marketing teams get a QR code module and a short URL module with hit counters and expiry dates, and redirects are created automatically whenever a page slug changes. The Form Framework builds forms with multiple file uploads in one field, CKEditor 5 text editing, and email notifications customized in the backend. A dashboard shows widgets such as recent documents and backend logins, and a Bookmark Manager groups shortcuts into large page trees. The Camino starter theme gives integrators a ready-made frontend with several color schemes, and developers shape sites further with Fluid templates and TypoScript, plus extensions from extensions.typo3.org. 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.

Wallabag
With 12,800+ GitHub stars and over a decade of active development since 2013, wallabag is the most established open-source read-it-later application — built for readers who want complete ownership of their article archive without depending on services that shut down (RIP Pocket). The Symfony-based PHP application extracts clean article content using Graby and php-readability, stripping advertisements, pop-ups, and tracking scripts to deliver a distraction-free reading experience optimized for both desktop and mobile screens. Save articles via Chrome, Firefox, or Safari browser extensions, Android and iOS native apps, REST API, or the built-in bookmarklet — all syncing to your self-hosted instance. Organize your library with tags, automated tagging rules that classify articles by content patterns, starred favorites, and archived collections. The annotation system enables highlighting extracts and attaching notes directly within articles for research and reference workflows. Import your existing reading lists from Pocket, Omnivore, Instapaper, Pinboard, Readability, and browser bookmarks. Export articles in PDF, ePUB, MOBI, JSON, CSV, TXT, or HTML for offline reading on Kindle, Kobo, and other e-readers. Full-text search with filters by reading time, domain, language, and creation date makes retrieval instant across thousands of saved articles. RSS feed output integrates with feed readers and automation services. Docker deployment with SQLite, MySQL, or PostgreSQL persistence backends takes under five minutes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
Pages CMS
Editors can update a static website without learning Git, because Pages CMS puts a visual editor on top of the repository itself. A single .pages.yml file defines what is editable: collections of Markdown files that share a schema, standalone files such as site settings, and nested groups that organize the sidebar. Fields cover strings, rich text, code, dates, numbers, booleans, selects, images, files, references, objects, and repeatable blocks, with front matter stored as YAML, JSON, or TOML. Plain text files like robots.txt open in a raw editor, redirect files in a code editor, and CSV files as an editable datagrid. Collection lists can be searched, sorted, and shown flat or as a folder tree. The media manager supports drag-and-drop uploads, multi-file selection, allowed extensions, and safe or random renaming. People without GitHub accounts join through email invitations and edit content and media, with their saves committed through the GitHub App. Custom action buttons dispatch GitHub Actions workflows after a confirmation dialog or input form, so one click can rebuild a preview or deploy the site. Commit message templates and a choice of app or user commit identity shape how each save appears in Git history. The responsive interface works on mobile screens, and suits Jekyll, Hugo, Astro, Next.js, Eleventy, VuePress, and similar site generators. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
Magento Open Source
One admin panel, many storefronts: Magento Open Source is a free ecommerce platform for selling online under separate domains, category trees, languages, and currencies from a single install. Catalog managers create simple, configurable, grouped, virtual, bundle, and downloadable products and organize them with categories and attribute sets. Merchandisers assemble CMS pages, blocks, and product and category content in Page Builder by dragging rows, columns, tabs, banners, sliders, videos, and product lists onto a visual stage. Catalog price rules and cart price rules with coupon codes drive promotions, and customer groups such as Wholesale and Retailer can get targeted discounts and their own tax class. Shoppers browse the Luma storefront theme and check out as guests or with accounts. Staff then take each order through invoice, shipment, and credit memo, while Multi-Source Inventory tracks stock across warehouses, stores, and drop shippers. Built-in sales, customer, and product reports show what sells, and Login as Customer lets permitted staff view the storefront as an opted-in shopper sees it. Import and export tools move products and customers in bulk, and the REST and GraphQL APIs let ERPs, shipping tools, and headless front ends read and write store data. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. OSL-3.0 licensed.
PandaWiki
In seven wizard steps, PandaWiki sets up a product docs, manual, FAQ, or blog site whose built-in AI answers visitors using only your own content. Those visitors can chat with an assistant that cites its sources and accepts image questions, or switch to a docs-only search that lists ranked pages with summaries. Publishing stays under control: each document has three switches, visible in navigation, reachable by URL, and answerable by AI, and nothing appears or gets learned until it is published. Authors write in a Markdown and HTML editor, or import from URLs, RSS and Atom feeds, sitemaps, offline .txt, .md, .xlsx, .docx, and .pdf files, Notion, Yuque, SiYuan, Wiki.js, Feishu, Confluence, and DingTalk. Pages export to Word, PDF, or Markdown. The wizard covers models, domain, HTTP or HTTPS ports, import, publishing, answer testing, and page decoration. One knowledge base can also feed a web widget and DingTalk, Feishu, WeCom, and Discord bots. Administrators get a dashboard of visits, questions, visitor regions, hot documents, and referring domains. Chat models come from Baizhi Cloud, DeepSeek, OpenAI, or Ollama, while vector and reranking models are built in. The open-source edition covers one wiki site, 300 documents, and one admin, and its console and documentation are in Chinese. 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.
Mixpost
Mixpost puts Facebook, Instagram, X, LinkedIn, YouTube, TikTok, Pinterest, Threads, Bluesky, Mastodon, Pixelfed, and Google Business under a single scheduling dashboard — plan content visually on a drag-and-drop calendar, queue posts for optimal engagement windows, and track audience growth per platform without juggling twelve separate apps or paying per-seat SaaS fees. Built on Laravel with a Vue.js 3 and Inertia.js frontend styled with Tailwind CSS, the Lite edition provides unified content management where each post supports platform-specific customization with individual captions, media attachments, hashtag groups, and first-comment scheduling. Posting queues automate publishing at configurable time slots throughout the day. The media library provides a centralized asset manager with drag-and-drop uploads, stock photo integration via Unsplash, and Tenor GIF search. AI-powered content assistance generates and optimizes post copy. Per-platform analytics dashboards display audience growth, engagement metrics, reach, and impressions with exportable reports. Team workspaces support role-based permissions for collaborative content management across departments. External integrations connect through the REST API, webhooks, n8n, Zapier, and RSS feeds, plus an MCP server for AI assistant publishing. Deploy via Docker Compose with MySQL and Redis. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
Wagtail
Backed by over 20,000 GitHub stars, 800 contributors, and organizations like Google, NASA, and the NHS, Wagtail is the Django-powered content management system that gives editors creative freedom through StreamField while keeping developers in full control of data structure and front-end rendering. StreamField lets editors compose pages from a custom library of content blocks — rich text, images, embedded videos, tables, code snippets, and developer-defined custom types — without compromising the underlying data model or breaking responsive layouts. The built-in JSON API supports headless deployments with versioned endpoints for pages, images, and documents, enabling decoupled front-ends in Next.js, Nuxt.js, or any framework that consumes REST. Editorial workflows provide configurable approval chains where content moves through draft, review, and publish states with commenting, task assignment, and email notifications built into the admin interface. Integrated search connects to Elasticsearch for full-text indexing with faceted filtering, or falls back to PostgreSQL and SQLite backends with fuzzy matching support added in v7.4. Multi-site management serves multiple domains from a single Wagtail installation with independent page trees, while the internationalization framework handles content translation with locale-aware URL routing. Image management includes focal point detection, responsive renditions, and automatic format conversion. The platform supports Django 5.2 and 6.0 with Python 3.10 through 3.14 and PostgreSQL, MySQL, MariaDB, or SQLite databases. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. BSD-3-Clause licensed.
Payload CMS
Backed by 44,000 GitHub stars and now part of Figma, Payload is the first headless CMS that installs natively into your Next.js application's /app directory rather than running as a separate service. The code-first architecture uses TypeScript config files to define collections, globals, and field schemas — from which Payload auto-generates database tables with migrations, a fully customizable React admin panel, REST and GraphQL endpoints, and type-safe Node.js local APIs you can call directly in React Server Components. The Lexical-based rich text editor supports block-based layout building, inline media embeds, and nested field structures, while the built-in localization engine handles unlimited locales with field-level translations. Authentication ships out of the box with HTTP-only cookie sessions, CSRF protection, role-based access control definable at the document, field, and operation level, and support for OAuth providers. Version history tracks every document change with full draft and publish workflows, and Live Preview renders content edits in real-time using server components. The job queue system manages background tasks and multi-step workflows deployable via Vercel Cron or standalone workers. Database flexibility spans PostgreSQL, MongoDB, and SQLite through swappable adapters, and the plugin ecosystem includes official modules for SEO, form builders, redirects, nested documents, and search alongside hundreds of community extensions. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
Strapi
The leading open-source headless CMS with over 72,800 GitHub stars and more than 20 million npm downloads, Strapi has powered content APIs for thousands of organizations since its creation in 2015, providing a complete backend for websites, mobile applications, IoT devices, and any frontend framework through auto-generated REST and GraphQL endpoints. The visual Content-Type Builder lets editors define collections, single types, components, dynamic zones, and relations without code, while Strapi AI introduced in 2026 generates complete content schemas from natural language descriptions, Figma file uploads, or existing JavaScript application code analysis. Version 5 rewrote the platform with a TypeScript-first architecture, replacing the Entity Service with the Document Service API, switching admin panel builds from Webpack to Vite, and integrating internationalization directly into core with unlimited locale support. Database flexibility spans PostgreSQL, MySQL, MariaDB, and SQLite with automatic migration handling. The media library manages uploads to local storage, Amazon S3, or Cloudinary with image optimization and responsive formats. Granular role-based access control defines permissions per content type, field, and locale. The plugin marketplace extends functionality with GraphQL, SEO, email, custom fields, and community contributions, while lifecycle hooks, custom controllers, and middleware enable arbitrary backend logic. Draft and publish workflows, webhooks for external system integration, API token authentication, data import and export, and CRON job scheduling round out a platform that handles content operations from prototype to production. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
CommaFeed
CommaFeed delivers the Google Reader experience on your own infrastructure with modern performance characteristics. The Quarkus-based Java backend compiles to native code via GraalVM, achieving sub-second cold starts and 50MB memory footprint — a fraction of traditional JVM RSS readers. Four distinct layouts (title-only, expanded, magazine, and card) with light and dark themes adapt to any reading style, while comprehensive keyboard shortcuts cover navigation, marking, starring, and feed management without touching a mouse. The Fever-compatible API and newly added Google Reader API connect native iOS and Android apps (Reeder, Unread, FeedMe, ReadKit) directly to your instance. Per-feed push notifications through ntfy, Gotify, or Pushover alert you to new articles instantly. The visual query builder for automatic read-marking rules replaces raw expression syntax with an intuitive condition editor supporting title, content, author, and URL matching. OPML import and export enable seamless migration from any RSS service. Custom CSS and JavaScript injection let power users completely restyle the interface, while the browser extension adds one-click subscription from any website. Docker images for linux/amd64 and linux/arm64 with H2 embedded database require zero configuration to start. 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.
Umbraco CMS
If editors should publish without waiting on developers, and developers should keep full control of the design, Umbraco is the free content management system built around that split. A page begins in the Block Grid editor, where reusable blocks nest inside Areas and each block is sized on a column and row grid. Live preview shows the result before anything goes out. Publish and unpublish times can be scheduled in the editor's own time zone, and any page can roll back to an earlier version from its Info tab. One content node can exist in several languages, and split view puts two of them side by side. The Media section holds images, video, and other files. Visitors can register and log in as members, new members can be placed in member groups, and pages can be hidden from anyone not logged in. On the code side, templates and partial views shape the front end, while the opt-in Content Delivery API returns content items as JSON for mobile apps and any other front end. Webhooks notify outside services when content is published, unpublished, or deleted. Custom dashboards and property editors extend the backoffice, and the Marketplace lists open-source and commercial packages for the rest. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
