Where PostWire is ahead
- The lowest bill of the three for an agency. 10 clients on 5 networks: $29 a month on PostWire Pro, every network included. bundle.social: $100; Postiz: $99.
- Each network's post written for you from one idea, in one request — a hook-first TikTok caption, a YouTube title and tags, a longer LinkedIn post. bundle.social takes one post with platform-specific payload blocks that you fill (its MCP page, Oct 9, 2026).
- A free hosted plan, no card, no time limit, with the API and MCP. Postiz's hosted plans start at $29 a month after a 7-day trial.
- A hosted MCP server you add to Claude by signing in (OAuth 2.1). bundle.social's MCP server runs locally with npx and an API key; a hosted one is on its roadmap.
- No server and no app reviews to run. TikTok Direct Post (Jul 7, 2026) and Meta (Jul 14, 2026) are approved for PostWire's apps; you connect with one click. Self-hosting Postiz means your own developer apps, so TikTok's audit and Meta's review are yours to pass.
- $29 for 10 businesses, every network included. bundle.social's first paid plan is $100 a month (Pro).
- Media by URL in the same request. bundle.social's post body takes upload IDs, so each file is uploaded first (its docs).
