Postiz

Postiz is an open-source social media scheduling tool that plans, generates, and publishes content across more than 30 networks from a single dashboard. On the surface it does what Buffer or Hootsuite do, you draft posts, customize them per platform, drop them on a visual calendar, and let it publish on schedule. What sets it apart is that it's fully open-source under AGPL-3.0, you can self-host the whole thing for free, and it's built from the ground up to be driven by AI agents and automation rather than just clicked through by a human. The platform was created by Nevo David, who also runs Gitroom, and the source lives on GitHub at gitroomhq/postiz-app where it's collected roughly 30,000 stars. It runs on a modern Next.js, NestJS, Prisma, and Temporal stack, and the hosted documentation, public roadmap, and active Discord make it feel like a living project rather than an abandoned repo. That matters, because self-hosting only pays off when the project is maintained, and Postiz ships frequent releases. The channel coverage is genuinely broad. Beyond the obvious ones, Facebook, Instagram, Threads, LinkedIn, X, TikTok, YouTube, Pinterest, Reddit, you get Bluesky, Mastodon, Discord, Slack, Telegram, Google My Business, Whop, Twitch, Skool, Nostr, plus blogging targets like WordPress, Medium, Dev.to, and Hashnode. For anyone publishing across the fediverse or niche developer platforms, that reach is hard to match. The AI content suite handles text generation tuned per platform, hooks, captions, threads, hashtags, plus image generation and short video generation with monthly limits, and an interactive chat agent that can take a post from idea to scheduled in one flow. Where Postiz really separates itself is the developer and agent layer. It ships an MCP server, so you can drive posting directly through Claude, ChatGPT, Cursor, or other agents using natural language. It exposes a public REST API with OAuth2 for creating posts, uploading media, and managing integrations, plus webhooks. It has a dedicated n8n node published to npm, a native Make.com integration, and Zapier support. There's even an AI Agents CLI for posting from the terminal. If your goal is to wire social publishing into an automated content pipeline, very few tools in this category were designed for that from day one the way Postiz was. Add unlimited team members and customer groups on the higher tiers, approval workflows, evergreen post recycling, RSS auto-posting, and a unified analytics dashboard pulling from official platform APIs, and it covers the agency use case too. Pricing splits cleanly. Self-hosting is genuinely free if you bring your own server and are comfortable running a Next.js plus NestJS plus Temporal stack in Docker. If you'd rather not, the hosted version runs four tiers, all roughly 20 percent cheaper on annual billing. Standard is $29 a month for 5 channels, 400 posts, solo use, 20 AI images, 3 AI videos, and 2 webhooks. Team is $39 for 10 channels, unlimited posts, unlimited team members, 100 AI images, 10 videos, RSS auto-posting, and 10 webhooks. Pro is $49 for 30 channels, 300 AI images, 30 videos, and 30 webhooks. Ultimate is $99 for 100 channels, 500 AI images, 60 videos, and unlimited webhooks. There's also a limited freemium tier. Note that each connected account counts as a channel, so three Facebook pages eat three slots. The weaknesses are mostly the flip side of its strengths. Self-hosting is free in dollars but not in effort. Running and maintaining a Temporal-backed stack is real ops work, and it's not for someone who just wants to schedule a few posts. The AGPL-3.0 license is a blocker if you want to fork and embed it in a closed commercial product. The hosted AI image and video allowances are capped per tier, so heavy generators will hit limits, and the channel caps on lower tiers push agencies toward the pricier plans. Analytics depth also depends on each platform's API, so smaller networks expose less data. Who should use it. Developers and automation teams wiring social posting into AI agents or n8n pipelines, agencies that want to self-host one instance and manage many client accounts cheaply, and creators who specifically want an open-source, self-ownable alternative to closed schedulers. Who should skip it. Non-technical solo users who just need a simple cloud scheduler and don't care about MCP, API, or self-hosting will find tools like Buffer simpler, and anyone needing a closed-source commercial fork is blocked by the license. In the scheduling category Postiz is the standout pick for the technical, agent-first, automation-heavy crowd.
