Where PostBoost is weaker
- 12 networks. Postiz (30+), Upload-Post (22), Zernio (15 plus ad networks) and Ayrshare (14) cover more, including Telegram, Discord or WhatsApp.
- No native n8n, Make or Zapier app yet. You connect with an HTTP request node and an API token.
- MCP uses an API token (Bearer) today. OAuth sign-in for MCP clients is in progress.
- The Free plan holds 3 queued posts at a time. Paid plans have unlimited scheduled posts.
- First comments on Facebook Pages and Instagram are pending Meta's app review. See the network permissions status.
