Buffer and Hypefury, taken on by an open-source, agentic social media scheduler: Postiz is a Next.js application with no feature gap between hosted and self-hosted versions. Connect 28+ platforms (X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Facebook, Pinterest, Bluesky, Mastodon, Discord, Slack, and more), then draft, schedule, and analyze everything from a unified visual calendar. Platform-specific depth is real: Reddit flairs and subreddit search, YouTube playlists and categories, LinkedIn company pages and carousels, Pinterest boards, X reply controls. A built-in AI agent drafts hooks, captions, and threads tuned per platform, generates images from prompts, and can execute an instruction like "write a LinkedIn post about X, make a matching image, schedule it for Tuesday at 9am" end to end. The agentic angle extends outward: a CLI and MCP server let Claude, Codex, and other AI agents drive Postiz autonomously - discovering connected integrations, fetching platform constraints, uploading media, and batch- scheduling campaigns with structured JSON output. A public REST API plus n8n, Make.com, and Zapier integrations trigger posts from CI, a CMS, or any event source. Team features cover invites, comments, and collaborative scheduling. Self-hosting removes per-channel pricing and keeps OAuth tokens on your box.
