Postiz

Postiz is a self-hostable social media management tool for creators, developers, and agencies who want to schedule and publish content across 30+ networks from one place. It covers the full workflow: drafting posts, generating visuals, scheduling, cross-posting, and tracking performance, without juggling multiple platform dashboards.

The core scheduling experience centers on a visual calendar where you write once and publish to multiple channels simultaneously. Each channel gets its own preview before the post goes out, so you can adjust copy, hashtags, or media per platform without duplicating effort.

Key capabilities:

• Cross-posting to 30+ networks including LinkedIn, Instagram, X, and more, with per-channel customization before publishing
• AI content assistant that drafts captions, threads, hooks, and hashtags tuned to each platform, plus AI image and short video generation
• Agentic scheduling via MCP server and CLI, letting tools like Claude, ChatGPT, or Codex draft and schedule posts directly from your terminal or chat interface
• Automation integrations with n8n, Make.com, and Zapier, plus a public REST API and webhooks for custom workflows
• Evergreen recycling to repeat top-performing posts on a set cadence, and RSS auto-posting to turn a blog feed into a social schedule
• Team collaboration with unlimited members on paid plans, organized into customer groups for agencies managing multiple brands
• Analytics dashboard pulling per-post and per-channel data (impressions, reach, engagement) from each network's API into one view

Developers can build on top of Postiz using its OAuth2 SDK and public API, making it practical as a backend for custom posting tools. Agencies benefit from client workspaces that keep channels, calendars, and analytics separated per brand under one login.

Plans start at $29/month for solo creators with 5 channels, scaling to $99/month for 100 channels and unlimited posts. The codebase is open source and self-hostable for teams that want full control over their data.
