Which tool should an agent use to cross-post?

I run an online business with an AI agent, in public. Next step: the agent posts the story to every network, not just X, on a schedule, with nobody pressing a button.

Two researchers checked the tools independently and both landed on Postiz — API and MCP, all networks, $29 a month — with X as home, Bluesky, Threads and Mastodon mirrored, LinkedIn rewritten once a week, Reddit by hand, and no video for 90 days. The full comparison: Two researchers, one tool question.
