Postiz Review

Postiz is an open-source social media scheduler for planning, creating, and publishing content across networks such as X, LinkedIn, Instagram, Facebook, TikTok, YouTube, Threads, Bluesky, Mastodon, Reddit, and Discord. It is built as a pnpm monorepo with a Next.js frontend and a NestJS backend, and it can be self-hosted or used as the managed Postiz Cloud.

The documented self-hosting path is the postiz-docker-compose repository: configure environment variables, run docker compose up, and open the app on port 4007. Since v2.12.0, Postiz requires the Temporal workflow engine (it replaced the older BullMQ queue), which adds services to run, and upgrading from v2.11.x needs a separate Temporal migration guide. The docs mention a tested setup with 2 vCPUs and 2 GB of RAM. When self-hosting, you also create and get approved for developer apps on each social network, which is usually the slowest part of the setup.

The interface centers on a visual calendar where you draft a post once, tweak the copy and media per channel with live previews, and schedule it. The official site describes Admin and Member roles, a built-in design editor, and an in-app AI agent that can draft and schedule posts from a chat. We did not test the interface hands-on; this section reflects the official documentation and product pages.

• Calendar scheduling and cross-posting to 30+ networks with per-channel previews
• AI assistant for hooks, captions, threads, hashtags, images, and video
• Hosted MCP server with OAuth sign-in, plus a CLI and skill for AI agents
• Public REST API and webhooks, with n8n, Make.com, and Zapier integrations
• Repeated (evergreen) posts and RSS auto-posting
• Analytics for impressions, reach, and engagement, plus customer groups for agencies

• Widest network coverage among open-source Buffer alternatives
• Very active project: about 37,000 GitHub stars, frequent releases, and a commit the day before this review
• Strong automation story with an API, webhooks, MCP, and a CLI for agents

• Self-hosting is demanding: Temporal is required on recent versions, and upgrades across v2.12.0 need a migration
• You manage API credentials and app approvals for every network when self-hosting
• AGPL-3.0 means a modified version offered over a network must share its source
• AI image, video, and clipping allowances are tied to the paid cloud plans

Self-hosting is free apart from your own server. Postiz Cloud has no permanent free tier: every plan starts with a 7-day trial, then Standard is $29/month for 5 channels, Team $39 for 10, Pro $49 for 30, and Ultimate $99 for 100, with roughly 20% off when billed annually. Posts are unlimited on all plans.

Postiz and Buffer cover the same core job: queue and schedule posts across social networks from one calendar. Postiz adds more networks, a public API, MCP and agent access, and the option to self-host, while Buffer is a simpler hosted product with no infrastructure to run. Postiz Cloud pricing starts at $29/month for 5 channels, so the savings come from self-hosting, not from the hosted plans.

• Teams and creators who want Buffer-style scheduling on their own infrastructure
• Agencies managing several brands, using customer groups and team roles
• People who want AI agents or n8n/Make/Zapier workflows to publish posts

• Anyone who does not want to run Docker, Temporal, and per-network developer apps
• Solo users who only need a few channels and a simple queue
• Organizations that cannot accept AGPL-3.0 obligations on modified deployments
