Hookpost is a social media scheduler built around two ideas.
First, the calendar. One visual drag-and-drop calendar covers 17 networks - Instagram, YouTube, LinkedIn, X, Facebook, Threads, Bluesky, Pinterest, Discord, Slack, Telegram, WordPress, Medium, Hashnode, DEV.to, Lemmy and Nostr. You write once, then adjust per channel where the platforms differ. Pricing is flat per plan, with no per-channel surcharge.
Second, the agent. Hookpost ships a Model Context Protocol server, so AI coding agents such as Claude Code, Cursor and Windsurf can draft a post and put it in the queue without anyone opening the app. There is also a REST API and webhooks.
Scheduling runs on Temporal workflows rather than a cron job. If the worker dies halfway through publishing a thread, the workflow resumes from the step it reached instead of losing the post or publishing it twice.
Self-hosting is supported with Docker Compose. The free tier is permanent - two channels and 30 posts a month - rather than a time-limited trial.
