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.

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.

Write one post and Shoutrrr publishes it across X, Bluesky, LinkedIn, Facebook, Instagram, Threads, and Discord at the same moment, or holds it in a queue until the slot you picked. The composer counts characters against each network's limits as you type, attaches media with alt text, adjusts wording per platform when a message needs a local tweak, and splits long posts into threads where the network supports them. Recurring posting slots follow your workspace timezone, drafts drop into those slots from a month calendar, and anything can still go out instantly when news breaks. Every target publishes independently and retries on its own when a network hiccups, leaving a per-attempt trail you can inspect instead of a silent failure. Analytics chart follower and post-count trends for each account and report likes, reposts, replies, and impressions per post wherever the network's API allows. Teams share workspaces with role-based memberships and email invitations, keep clients in separate workspaces, and get in-app alerts the moment a post lands, fails, or needs an account reconnected. Account tokens sit encrypted at rest and refresh themselves, sign-in supports two-factor codes and passkeys, and the built-in MCP server hands AI assistants 22 tools to draft and schedule while publishing, retrying, and deleting refuse to run without your explicit confirmation. 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.

Write a post once in LightPost and it goes out to Bluesky, Mastodon, X, Instagram, Threads, Discord, LinkedIn, Telegram, and Facebook Pages on your schedule, with YouTube video uploads handled in the same workspace, from a dashboard running on your own server. The composer fans one message out to every connected account, including several accounts on the same platform, and each destination can receive text, images, or both within that network's limits. Drafts can be saved, edited, and duplicated, and scheduled times follow your browser's timezone so a week of announcements can be queued in one sitting. Images come in from public JPEG links or a saved library, with alt text and a preview before anything ships. Every delivery is tracked per account with links to the published posts, and when one network fails you retry just that destination instead of blasting the successful ones twice. The queue persists across restarts and overdue posts resume on their own, so an overnight reboot never eats a scheduled campaign. Built-in setup guides walk you through eligibility, credentials, and permissions for each platform, account connections can be verified or reconnected from the same panel, and your credentials stay encrypted on your disk with optional password protection and exportable post history. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

BrightBean Studio provides an open-source social media management suite that centralizes multi-account publishing, visual calendar scheduling, idea tracking, and cross-channel analytics into a unified self-hosted dashboard. Content creators and marketing agencies draft cross-network posts within an interactive composer that provides real-time channel previews and custom caption overrides for individual networks. The visual drag-and-drop calendar maps publishing queues across recurring weekly time slots, while an integrated Kanban board organizes brainstorming concepts from unassigned ideation to production-ready schedules. Community managers monitor unified social inboxes aggregating direct messages, mentions, and comments across Facebook, Instagram, LinkedIn, YouTube, TikTok, Bluesky, Threads, Pinterest, and Mastodon. Team leads configure multi-tier approval workflows with threaded editorial comments and issue passwordless 30-day magic links so external clients can approve drafts without registration. Built-in performance dashboards aggregate engagement rates, follower growth curves, and watch time metrics directly from native network APIs without relying on third-party data aggregators. 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.

OpenPost is an open-source content creation and publishing suite that unifies multi-platform social scheduling, graphic design, and video editing into a single self-hosted control center. Creators can compose one primary announcement and tailor bespoke copy, media attachments, and thread structures across sixteen distinct networks including Bluesky, Mastodon, X, Threads, LinkedIn, YouTube, and Discord. The integrated browser canvas lets you design multi-slide carousels with custom typography, layer ordering, and automated background removal without juggling external design software. A built-in multitrack video suite allows you to trim footage, render subtitle captions, insert transitions, and slice clips directly by highlighting spoken words in generated transcripts. Social managers can organize campaigns through an interactive visual calendar, stagger deliveries across automated queues, and monitor unified comment streams to answer incoming audience inquiries directly from a single inbox. Teams can organize multiple independent client brands into partitioned workspaces with role-based permissions, automated repost policies, and programmable scheduling webhooks via native REST and Model Context Protocol endpoints. 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.

37Studio is a self-hosted AI video studio and social media desk that turns a short brief into on-brand videos, posts them to nine social platforms, and drafts replies to the messages that come back. Paste a company website and it builds a brand library of logos, photos, fonts, and colours, plus a knowledge base every later video and reply draws on. An editor agent builds each video as an animated composition, checks its own rendered frames, and takes revision requests in plain words. The same workflow yields hook reels, captioned clips, explainers, podcast clips, promo ads, and thumbnails, and any finished video can become a template. A two-hour recording becomes a shelf of short clips: transcription runs locally in about 100 languages at no cost, and YouTube or Drive links import directly. Publishing reaches Facebook Pages, Instagram, YouTube, TikTok, LinkedIn, X, Pinterest, Bluesky, and Mastodon in one action, now or scheduled, each with its own caption. Autopilot goes further: state a content plan in one sentence and a fresh video is made before every slot, waiting for one-click approval. Messenger, Instagram, and WhatsApp messages and social comments land in one inbox, with replies drafted in the customer's language under rules each brand sets. Exact AI spend shows on every project, and an MCP server lets your own AI tools run the studio. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Social Analyzer scans over 1,000 social media platforms in parallel to discover and correlate user profiles from a single username query, making it the most comprehensive OSINT reconnaissance tool of its kind. Three detection modes cover different accuracy and speed tradeoffs: fast HTTP library checks for rapid sweeps, Selenium WebDriver validation for JavaScript-heavy sites, and a special mode for stubborn edge cases. String analysis generates username permutations and combinations to catch related accounts with slight naming variations. Three interfaces serve different workflows: a Node.js web application on port 9005 with a browser-based GUI, a CLI for scripted batch operations, and Python plus Node.js APIs for embedding into automated investigation pipelines. The QeeqBox OSINT library extracts profile metadata, screenshots, titles, descriptions, and activity patterns, all visualized through Ixora-based force-directed graphs that map relationships between discovered accounts. Tesseract OCR analyzes profile images for additional detection vectors. Search results narrow by country codes, website categories, Alexa ranking thresholds, and confidence levels. Optional Google API and DuckDuckGo API integration adds search engine correlation alongside direct platform queries. Docker deployment bundles Node.js, Firefox ESR, Tesseract, and all dependencies into one container. Trusted by law enforcement and security researchers for digital forensics and identity verification. 23,000+ GitHub stars. AGPL-3.0 licensed.

With 11,000+ GitHub stars and over 1,291 releases since 2016, Misskey is the most feature-rich open-source microblogging platform in the Fediverse — federation-first social networking with capabilities that go far beyond simple status updates. The TypeScript and Vue 3 frontend delivers a highly customizable interface with drag-and-drop widget layouts, switchable themes, per-user custom CSS, and AiScript-powered plugins that transform every instance into a unique social experience. ActivityPub federation enables seamless interaction with Mastodon, Pixelfed, PeerTube, and any ActivityPub-compatible platform across the decentralized network. Emoji reactions let users respond with custom instance emojis instead of simple likes, while Misskey Flavored Markdown adds animated text effects, sparkle decorations, and rich formatting to posts. The built-in Drive provides personal cloud file management with folder organization for images, videos, and audio — eliminating the need for external storage services. Antennas create custom filtered timelines based on keywords, users, or criteria for monitoring specific topics. Channels offer topic-specific feeds separate from the main timeline. Pages enable users to build personal websites directly within their instance. Clips save and organize posts into curated collections. The Node.js backend scales with PostgreSQL for persistence, Redis for caching, and optional S3-compatible storage for media. Docker Compose deployment provisions the complete stack including the database and cache in under 15 minutes. 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.

With nearly 7,000 GitHub stars and instances spanning hundreds of federated servers, Pixelfed has become the leading open-source alternative to Instagram — delivering ad-free, algorithm-free photo sharing across the Fediverse. Built on Laravel with a Vue.js frontend, Pixelfed provides a polished, mobile-responsive interface where users upload photos and videos, apply built-in filters, create multi-image posts with alt text, share ephemeral stories, organize content into curated collections, and exchange direct messages — all without tracking, algorithmic manipulation, or targeted advertising. Federation through the ActivityPub protocol means Mastodon, Pleroma, and other Fediverse users can follow Pixelfed accounts, view photo posts in their timelines, and interact through likes, boosts, and replies, while Pixelfed users can discover content through both local and federated timelines. Instance administrators control registration policies, content moderation rules, federation blocklists and allowlists, storage backends including local or S3-compatible options, and server-wide settings. The Mastodon-compatible API enables third-party mobile app support alongside the built-in Progressive Web App experience. Advanced features include blurhash image placeholders for smooth loading, federated groups for community building through FEP-400e and FEP-1b12 extensions, HTTP Signatures with Authorized Fetch for secure federation, and comprehensive data export for full portability. Deployment requires PHP 8.1+, MySQL or PostgreSQL, Redis, and a reverse proxy, with Docker Compose configurations available for streamlined setup.

A campaign engine wrapped around a contact database: Mautic, the largest open-source marketing automation platform, replaces HubSpot or Marketo without per-contact pricing. Contacts arrive through forms, landing pages, imports, or the REST API and flow into segments: dynamic filters that update automatically from behavior, custom profile fields, or point scores. Segments decide who qualifies; campaigns decide what happens. The drag-and-drop Campaign Builder composes multi-step workflows from actions, positive/negative decision trees, and conditions (field values, tags, device type, segment membership, point thresholds), with static or relative delays, a Jump-to-Step action for moving contacts between branches, and handoffs that push contacts into CRMs or entirely different campaigns. Messaging covers email, SMS, and web/app push out of the box, with A/B testing and a drag-and-drop email builder; dynamic website content swaps page sections per known contact. Lead scoring assigns points for clicks and visits with decay for inactivity, while stages track funnel position. Native integrations cover Salesforce, HubSpot, Zoho, and Dynamics, plus a full REST API for custom sync. It runs on PHP and MySQL with cron jobs processing campaigns and segment rebuilds - self-hosting keeps your entire contact database and behavioral history under your control.

Among open-source Mailchimp alternatives, Keila has the most modern UI - built in Germany on Elixir and Phoenix (the PETAL stack), with GDPR-conscious defaults including an optional no-tracking mode, and 100% open source with no proprietary premium tier. Campaign authoring is flexible three ways: a visual block editor with multi-column layouts, Markdown with or without WYSIWYG for hybrid HTML-plus-plain- text sends, and raw MJML for hand-coded designs. The personalization system is unusually clean - every contact carries custom data as a single JSON object (populated from sign-up form fields or pushed from your CMS/CRM), and Shopify's Liquid template language renders it into fully dynamic emails. Targeting uses a visual segment editor backed by a powerful segment language for complex logic over tags, language preferences, and any custom field. Sign-up forms with custom fields grow your lists; open and click tracking measures campaigns; scheduled sending handles timing. Delivery pipes through your own SMTP or first-class integrations with AWS SES (including automated bounce handling), SendGrid, Mailgun, and Postmark. A full REST API manages contacts, campaigns, and segments, with Erlang/OTP reliability underneath. Comfortable at 100K+ subscribers. AGPL-licensed, EU-hosted project, actively developed.
