Where PostDelegate fits
PostDelegate is a lighter alternative to both: a scheduler with flat plans from $19, team members from $29 and the API and MCP server on every plan, with AI on your own assistant or key. It cannot reach Facebook, Instagram, Threads, TikTok, LinkedIn, Pinterest or Reddit yet, because those are waiting on platform approval, and X is not available. Every plan starts with a 7-day trial and no card.
