PostWire vs Upload-Post

Short answer: Both post to social media via API. PostWire is built for AI agents — it ships a real MCP server, uses flat per-brand pricing (no per-profile tax), and cross-posts to TikTok, YouTube, Bluesky, Telegram, Mastodon & Discord from one call. Choose PostWire if you want predictable pricing and agent/MCP support out of the box.

FAQ

Can I move from Upload-Post to PostWire easily?
Yes. PostWire uses the same connect-once-then-post model and a single REST endpoint, plus an MCP tool, so most integrations are a one-line change.
Which platforms are live on PostWire?
Bluesky, Telegram, Mastodon and Discord are live now. TikTok and YouTube are in platform review/verification (June 2026) and their endpoints are already shipped.
