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.

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.

TryPost is an open-source social media scheduler that publishes natively to thirteen networks from one composer, calendar, and queue, whether the author is a person on your team or an AI agent connected over MCP. Write a post once and it adapts per network, with a live preview of each version, character quirks handled, and an AI assistant in the editor to rephrase, shorten, or expand when a caption fights back. Posts land on each channel's own posting times in its queue, the calendar shows the whole month at a glance, and anything can be dragged to a new slot when plans change. Members who need a second opinion send work for approval, and admins approve or reject in one click, which is how agencies keep many brands from becoming many headaches. Workspaces keep every client apart with its own channels, members, and settings, while signatures save the hashtag and call-to-action blocks you refuse to retype and labels color-code the calendar. Insights follow followers and post performance across channels, Repurpose copies videos you posted elsewhere onto your other networks automatically, and webhooks announce every created, published, or failed post to your other tools.

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.

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.
